Abstract

1,114,067. Valves. GEORG FISCHER A.G. 21 June, 1966 [22 June, 1965], No. 27764/66. Heading F2V. A high-pressure non-return valve for connection in a pressure-medium carrying line comprises an interconnected two-part valve housing 1, 2 containing a valve member 4 which incorporates an intermediate peripheral shoulder 15 for slidable co-operation with inner cylindrical surface 16 of housing part 1, a valve head 5 located on one side of the shoulder having a face co-operating with a valve seat provided in the housing part 1, a hollow shank remote from the valve head engaging in a concentric reduced diameter recess 21 provided in the housing part 2, neck 9 behind the valve head from which convergent bores 10 extend into the hollow shank and through which the pressure medium can pass, in an open position of the valve, from housing part 1 to housing part 2, a loading spring 14 disposed around the shank between the intermediate shoulder 15 and a shoulder face 17 of housing part 2 and contained in an annular compartment 13. There is at least one radial aperture 12 in the hollow shank communicating with the annular compartment 13 whereby the pressure medium can enter the compartment to dampen the displacement of the valve member. An O-ring 6 is carried in an annular groove 7 in the valve face and provides a durable and fluid-tight seal for the valve closure member 4. Hexagonal faces are provided on the outer surfaces of the housing parts 1 and 2 to facilitate interconnection.
