Abstract

An open end, circular valve housing having a cover for the open end of the housing receives an oscillatory valve body with one annular seal partially recessed into the housing and bearing against a groove in the edge of one surface of the valve body and a second seal partially recessed into the cover and bearing against another groove in the edge of the opposite surface of the valve body. There is a radial outlet port in the housing and three radial inlet ports, one 120*, and two others 90*, from the outlet. The body has five radial ports intercommunicating at the center, the middle port having two adjacent (outlet) ports spaced 30* to either side and two remote (inlet) ports spaced 120* to either side. By turning a handle connected to the valve body 30* to either side of a central position, any of the three inlet ports of the housing may be connected to the outlet port.

Claims

1. A valve having a housing formed with a central cavity, a circular body in said cavity, means for oscillating said body in said cavity about its axis between a plurality of positions of adjustment, an outlet port in said housing, a first inlet port in said housing spaced 120* from said outlet port, second and third inlet ports in said housing each spaced 90* to either side of said outlet port, all said ports in said housing extending radially relative to said axis and communicating with said cavity, said body formed with intercommunicating radial first, second and third outlet ports and first and second inlet ports, said second and third outlet ports in said body being spaced 30* to either side of said first outlet port, said first and second inlet ports in said body being spaced 120* to either side of said first outlet port.

2. A valve according to claim 1 in which each said port in said body is formed with a counterbore at its outer end and which further comprises an annular port seal in said counterbore bearing against said cavity.

3. A valve according to claim 1 which further comprises means on said body and said housing restricting oscillatory movement of said disc to 60*.

4. A valve according to claim 1 in which said housing is formed with a counterbore within which said body is received with the bottom of said body resting on the bottom of said counterbore and a cover secured to said housing engaging the top of said body.

5. A valve according to claim 4 in which said cover is formed with a circular projection dimensioned to fit inside said counterbore.

6. A valve according to claim 5 in which a first groove is formed in said counterbore, second and third grooves in the periphery of the top and bottom of said body and a fourth groove in the periphery of said projection and which further comprises a first annular sealing ring in said first and second grooves and a second annular sealing ring in said third and fourth grooves.
