。 A diaphragm that defines a working chamber and a pump chamber, communicates the working chamber with the inside of the crankcase where pulsating pressure acts, and has check valves installed in the liquid suction passage and discharge passage of the pump chamber, respectively. In the type fluid pump, a sub-pump section in which a sub-pump chamber and a sub-working chamber are defined by a diaphragm is provided on at least one of the suction passage side and the discharge passage side where the check valve is provided, and the sub-pump chamber is reversely connected. 1. A fluid pump characterized in that the pump chamber is communicated with through a stop valve, and the sub-working chamber is communicated with an intake pipe where pulsating pressure acts.
