ABSTRACT OF THE DISCLOSURE A hydraulic valve is disclosed which has a gasket sealing against and, to a limited extent axially movable on, a movable valve member. The valve member has a radial shoulder sealing surface which is spaced from a matching, larger diameter concentric radial shoulder sealing surface of the body of the valve. The sealing surfaces can be aligned with each other by an axial movement of the valve element, with a radial spacing between them providing a fluid passageway. The gasket has an angular cross-section, with the apex being toward where the sealing surface of the valve element adjoins the valve element surface over which the gasket extends outward from the axis of the valve element. The angular relationship between the aligned sealing surfaces and the sealing portion of the gasket is such that when the gasket is moved toward the sealing surface of the body by the valve element, the outer lip of the gasket sealing portion first contacts the surface, thus significantly blocking fluid flow. This causes the gasket sealing portion to be pushed by the fluid pressure itself so that the gasket rotates about its cross-sectional torsional axis to press the sealing portion flat against the aligned sealing surfaces and over the fluid passageway to block its flow. Various relative configurations of the gasket and sealing surfaces are disclosed. Also disclosed are combinations of such arrangements for forming multiple-function valves. 1.12.1978 Sb/VRU/lf
