プ。 The pump chamber is compressed and expanded by a piston that reciprocates as the rotating shaft rotates, and the fluid from the tank located above is sucked up to the suction valve side upstream of the pump chamber through the suction passage, and from this suction valve side. A piston pump that sucks and discharges fluid by sending it to a discharge valve side downstream of a pump chamber, characterized in that an air vent hole communicating with the suction valve side is connected to a tank side above the hole. .
