Abstract

PURPOSE: To obtain a versatile fluid feeding apparatus which is not affected by the installation position of a water tank etc., by installing a simple pressure-responding valve which opens and closes a passage through utilization of the discharge pressure which varies corresponding to the operation and stop of a pump.
CONSTITUTION: In a pressure responding valve 15, the discharge pressure of a pump which is generated by the operation of an oil feeding pump 14 is received by a cut-off valve disc 22, and pushes-up the valve disc 22 against an urging force of a spring 24, and the valve is opened. Although the discharge pressure after valve opening decreases, open state is kept by the operation of a diaphragm 23 having a pressure receiving area far larger than the cut-off valve disc 22, and fuel feeding is continued. When the oil feeding pump 14 stops, the cut-off valve 22 is closed by the action of the spring 24 described before, and the fuel feeding passage is intercepted perfectly, and effluence of fuel is prevented.
