ABSTRACT:
A dispenser (20), including a plunger (24) and cylinder (26) connected to a dispenser body (28), a flow control valve (54) is rotatably mounted in the dispenser body (28) and has a valve fluid path (92, 106, 108) connected between the cylinder (26) and a control valve outlet (109). Advancing the plunger (24) when the valve (54) is in a first, recirculate position pushes liquid from the cylinder (26), through a return path (112) and back into the bottle (22). Advancing the plunger (24) when the flow control valve (54) is in a second, dispense position delivers liquid from the cylinder (26) out through a dispensing orifice (120).
