ABSTRACT:
A check valve assembly for use as intake and discharge valves for pumps. The assembly includes a valve element made into a square configuration, the corners of which are slidably received in indexed relationship within radially spaced, longitudinally extending grooves formed into opposed, interior, peripheral wall surfaces of the pump housing and made complementary respective to the marginal area represented by the corners of the valve element. This configuration of the valve components prevents axial rotation of the valve element, and forms four radially spaced crescent shaped inlet and outlet passageways between each of the valve elements and the pump housing. An intake cage is axially spaced in opposed relationship respective to an exhaust cage by a valve plate, with the intake cage, exhaust cage, valve plate, intake and exhaust valve elements being concentrically arranged respective to one another. The entire check valve assembly is located at one end of a pump barrel, so that reciprocal movement of a pump piston reciprocatingly received within the barrel produces fluid through the check valve assembly.
