ABSTRACT:
A liquid dispenser comprising a dispenser body and a valve housing. The dispenser body has a pump mechanism, an intake port adapted for fluid communication with a source of liquid, and an intake liquid flow path providing fluid communication between the intake port and the pump mechanism. The dispenser body further comprises a discharge conduit and a discharge liquid flow path providing fluid communication between the pump mechanism and discharge conduit. The discharge conduit has a downstream end through which dispensed liquid exits the discharge conduit. The valve housing has first and second portions, a fluid passageway within the first and second portions, and a discharge port in the second portion and in fluid communication with the fluid passageway. The first portion of the valve housing is attached to the dispenser body adjacent the downstream end of the discharge conduit so that the passageway of the valve housing is in fluid communication with the discharge conduit. The liquid dispenser further includes a check valve positioned in the passageway of the valve housing. The check valve is moveable between a closed position for blocking fluid flow between the pump mechanism and discharge port and an open position for permitting fluid flow.
