ABSTRACT:
A flow control apparatus for regulating fluid flow through a plurality of tubular conduits which includes a housing and a pivotable control wheel capable of pivotal movement about the central axis thereof through a plurality of discrete positions defined peripherally therearound. The control wheel includes a cam profile edge circumferentially therearound adapted to abut a rocker member. The rocker member is movable between an initial flow position allowing flow through one tubular conduit while preventing flow through another and a final flow position preventing flow through the former tubular conduit and allowing flow through the latter tubular conduit. The rocker includes a first arm carrying a cam follower adapted to follow the cam profile edge to hold the rocker in the initial flow position and being responsive to movement into the cam slot means of the cam profile edge to facilitate movement of the rocker to the final flow position. First and second plungers are defined wherein the first plunger is moved toward the tubular conduits in the closed position responsive to the rocker being in the initial flow position and wherein the second plunger is movable toward the tubular conduits whenever the rocker is located in the final flow position.
