Abstract

A valve comprising a body including a plug receiving socket and including conduits in communication with the socket, with the body having an outwardly extending flange about the periphery of the socket, and a plug rotatably positioned in the socket whereby the plug can be rotated to register slots with the conduits to selectively control fluid flow through the conduits, the plug including a flange portion about the flange of the body wherein the flange on the body includes an upper bearing surface and a lower gripping surface, and the flange portion of the plug includes an upper gripping surface corresponding to the lower gripping surface of the flange on the body, whereby insertion of the plug in the socket causes the upper bearing surface to flex outwardly the flange portion of the body and the upper gripping surface constantly urges the lower gripping surface toward a sealing relationship with the plug in the socket.

Claims

1. In a valve comprising a body defining a plug-receiving socket and defining outwardly extending conduits in communication with the socket, said body having an outwardly extending flange about the periphery of the socket and a plug rotatably positioned in the socket, said plug having slots therein registrable with the conduits whereby rotation of the plug in the socket selectively controls fluid flow through said conduits, said plug including a flange portion about the flange of the body, the improvement wherein the flange on the body includes an upper bearing surface and a lower gripping surface and the flange portion of the plug includes spaced, inwardly extending ears, said ears defining an upper gripping surface corresponding to the lower gripping surface of the flange on the body whereby insertion of the plug in the socket causes the upper bearing surface to flex outwardly the flange portion of the plug adjacent said spaced ears, said plug flange portion being maintained in said flexed position so that the upper gripping surface constantly urges the lower gripping surface toward a sealing relation with the plug in the socket and said plug is capable of axial movement in said socket.

2. The valve as defined in claim 1 wherein at least the plug is formed of a resilient material having an elastic memory.

3. The valve as defined in claim 1 wherein the slots registrable with the conduits selectively open communication between the conduits and the socket whereby conduits are selectively communicative each with the other through the socket.

4. The valve as defined in claim 1 wherein said ear has a generally triangular configuration, with one side of the triangle opposite the flange portion defining the upper bearing surface.

5. The valve as defined in claim 1 wherein the flange on the body has a trapezoidal configuration, with two sides of the trapezoid defining the upper bearing surface and the lower gripping surface.

6. The valve as defined in claim 5 wherein the flange on the body is continuous.

7. The valve as defined in claim 1 wherein the flange on the body includes at least one interruption.

8. The valve as defined in claim 7 wherein the interruption is aligned with the plug to indicate the position of the plug relative to the conduits.

9. The valve as defined in claim 1 wherein the body defines three conduits in communication with the socket.

10. The valve as defined in claim 1 in which portions of said plug flange portion which are not adjacent said ears are not flexed outwardly.

11. In a valve comprising a body defining a plug-receiving socket and defining outwardly extending conduits in communication with the socket, said body having an outwardly extending flange about the periphery of the socket;

and a plug rotatably positioned in the socket, said plug having slots therein registrable with the conduits whereby rotation of the plug in the socket selectively controls fluid flow through said conduits, said plug including a flange portion about the flange of the body, the improvement wherein the flange on the body includes an upper bearing surface and a lower gripping surface and the flange portion of the plug includes spaced, inwardly extending ears, said ears defining an upper gripping surface corresponding to the lower gripping surface of the flange on the body whereby insertion of the plug in the socket causes the upper bearing surface to flex outwardly the flange portions of the plug adjacent to said spaced ears, said plug flange portion being maintained in said flexed portion so that the upper gripping surface constantly urges the lower gripping surface toward a sealing relation with the plug in the socket and said plug is capable of axial movement in said socket, said flange on the body including at least one interruption wherein the flange portion of the plug includes at least one projection dimensioned to be received through the interruption of the flange on the body, and the body includes a detent in alignment with the interruption adapted to receive the projection whereby the projection operates to lock the plug when the projection is engaged with the detent.

12. In a valve comprising a body defining a plug-receiving socket defining outwardly extending conduits in communication with the socket;

and a plug rotatably positioned in the socket, said plug having channel means therein registrable with the conduits, whereby rotation of the plug in the socket selectively controls fluid flow through said conduits;

first and second flanges respectively carried by said body and said plug, said first flange carried by the body extending about the periphery of said socket, said flanges being of differing diameters and positioned in generally coaxial relationship, whereby one flange occupies a position within the other of said flanges, the inner of said flanges defining a gripping surface for bearing in sliding relation against the outer of said flanges, the improvement comprising, in combination;

the outer of said flanges defining spaced, inwardly-extending ears, said ears defining gripping surfaces abutting the gripping surface of the inner flange, whereby the inner of said flanges causes the outward flexing of said spaced ears and the outer flange portions adjacent said spaced ears, to constantly urge, by interaction of the respective gripping surfaces, said plug and socket together into sealing relation, while at the same time permitting axial movement between said plug and socket.

13. The valve as defined in claim 12 in which portions of said outer flange which are not adjacent the ears are not flexed outwardly.

14. In a valve comprising a body defining a plug-receiving socket and defining outwardly extending conduits in communication with the socket, said body having an outwardly extending flange about the periphery of said socket;

and a plug rotatably positioned in the socket, said plug having slots therein registrable with the conduits whereby rotation of the plug in the socket selectively controls fluid flow through said conduits, said plug including a flange portion about the flange of the body, the improvement wherein the flange on the body includes an upper bearing surface and a lower gripping surface, and the flange portion of the plug carries a pair of spaced, inwardly extending ears, said ears being positioned in opposite relation to each other and defining an upper gripping surface corresponding to the lower gripping surface of the flange on the body, whereby insertion of the plug in the socket causes the upper bearing surface to flex the flange portion of the plug outwardly adjacent said spaced ears, said plug flange portion being maintained in said flexed position so that the upper gripping surface constantly urges the lower gripping surface and the plug toward a sealing relation with the socket.

15. In a valve comprising a body defining a plug-receiving socket defining outwardly extending conduits in communication with the socket;

and a plug rotatably positioned in the socket, said plug having channel means therein registrable with the conduits, whereby rotation of the plug in the socket selectively controls fluid flow through said conduit;

first and second flanges respectively carried by said body and said plug, said first flange carried by the body extending about the periphery of said socket, said flanges being of differing diameters and positioned in a generally coaxial relationship, whereby one flange occupies a position within the other said flange, the inner of said flanges defining a gripping surface for bearing and sliding relation against the outer of said flanges, the improvement comprising, in combination;

the outer of said flanges carrying a pair of spaced, diametrically opposed, inwardly-extending ears, said ears defining gripping surfaces abutting the gripping surface of the inner flange, and positioned whereby the inner of said flanges causes the outward flexing of said spaced ears and portions of the outer flange adjacent said spaced ears, to constantly urge, by interaction of the respective gripping surfaces, said plug and socket together in sealing relation.
