Abstract
A multiple function valve for a compressor cooling liquid system. A cylindrical valve housing has an inlet at one end and an outlet at the other with a flow passage therethrough. A thermal valve controls the liquid flow between the inlet and outlet and diverts liquid to a heat exchanger connected with ports in the valve body. A pressure responsive on-off valve is located between the thermal valve and the outlet. A filter is connected between the inlet and the thermal valve.
