ABSTRACT:
A dual-purpose diverter valve designed particularly to be incorporated within an air-pressure system associated with hot spas, tubs and the like, wherein air is pumped into the tub water to create a massaging action therein, the diverter valve comprising an enlarged cylindrical housing having an inlet port and an oppositely disposed outlet port, the inlet port being connected to the air-pump side and the outlet port being connected to the tub side; and wherein the housing thereof defines a transitory chamber in which there is provided a dual-valve arrangement, the dual valve being formed between the inlet port and a back-flow-vent port, the inlet port including an inwardly protruding angular-valve set having a flexible valve-flap member adapted to close the inlet passage when air is not being pumped to the tub, and wherein the flap-valve member is arranged to disengage from the inlet-passage valve set and engage the back-flow-vent port, thereby closing the vent port during air flow through the chamber.
