Abstract
A plural function, three member, fluid valve includes a stationary base member which provides plural fluid ports connected to apparatus requiring or providing fluid control, a first movable member containing conduits which are selectively movable into alignment with the ports of the base member to select the function(s) to be performed, and a second movable member having a U-shaped passageway for selectively connecting passageways of the first member to execute the selected function, i.e., to form a fluid conduit from one port of the base member through a conduit in the first member, the U-shaped passageway in the second member and a second conduit in the first member to another port in the base member. Methods are also disclosed.
