ABSTRACT:
A unitary inlet and outlet valve means for fluid flow control comprising a unitary body in the form of a hollow sleeve having coaxially arranged inlet and outlet valves. The sleeve housing means includes an inlet at one end thereof, and a flow chamber at the opposed end thereof, and with an annular flange extending outwardly from the sleeve adjacent the flow chamber. The central bore through the sleeve member provides a housing and seat for the inlet poppet, and an annular spring-biased ring controls fluid flow through bores formed in the flange and communicating between the flange and the flow chamber. The individual valves open upon opposed inwardly directed movement, thereby shortening the overall length of the valve body.
