Stop valve
First Claim
1. A valve member adapted to be rotatably received within a valve body to control the flow of fluid between an inlet and an outlet of the valve body, said valve member comprising:
- a valve stem extending from the valve body to facilitate manipulation of said valve member within the valve body, said valve stem having a substantially rigid material property; and
a valve sleeve attached to said valve stem such that manipulation of said valve stem is transmitted to said valve sleeve, said valve sleeve including an inner chamber and an outlet port wherein said valve sleeve is selectively movable between an open position directing fluid flow from the valve body inlet through said outlet port to the valve body outlet and a closed position, preventing fluid flow through said valve body, said valve sleeve being less rigid than said valve stem for improved sealing within the valve body.

Abstract
A stop valve includes a valve body, a multi shot resilient control sleeve, O-ring and handle. The control sleeve is molded to the valve stem to create an integral but separately molded fluid control member. Inlet line pressure resiliently biases the side walls of the control sleeve and a circumferential sealing flap formed thereon into sealing engagement with the valve bore to prevent leakage. The control sleeve consists of a hard plastic cylinder and a flexible barrel member molded as one consistent piece by a multishot molding process. The O-ring also serves as a backup seal to prevent leakage to atmosphere. A valve handle is secured to the valve by either a screw or a snap protrusion.

11. A valve for controlling fluid flow between a fluid inlet and a plumbing fixture, said valve comprising:
-
a valve body having a housing chamber with an inlet port in communication with the fluid inlet and an outlet port in communication with the plumbing fixture, said valve body including an aperture;
a valve member rotatably received within said valve body, said valve member including;
a valve stem extending through said aperture of said valve body to facilitate manipulation of said valve member within said valve body, said valve stem having a substantially rigid material property; and
a valve sleeve attached to said valve stem such that manipulation of said valve stem is transmitted to said valve sleeve, said valve sleeve including an inner chamber and an outlet port, said valve sleeve having elastomeric properties less rigid than said valve stem for improved sealing within said housing chamber of said valve body; and
a handle connected to said valve stem for selective manipulation of said valve member within said valve body. - View Dependent Claims (9, 12, 13, 14, 15, 16, 17, 18, 19, 20)
