フラム型無脈動ポンプ。[Scope of claim for utility model registration] A pump chamber, a hydraulic chamber filled with hydraulic oil,
a diaphragm that partitions the hydraulic working chamber and the pump chamber; a main cylinder that supplies and discharges the hydraulic fluid to and from the hydraulic working chamber and drives the diaphragm; A hydraulic diaphragm type non-pulsation pump comprising an oil replenishment valve that instantaneously injects a small amount of hydraulic oil into a hydraulic chamber, wherein the oil replenishment valve has a communication position where the hydraulic operation chamber and the oil reservoir chamber communicate with each other. and a closed position that closes the communication; a spring means that biases the valve body to the closed position; and an external pressure oil supply means that moves the valve body to the communication position. and a leak hole that is closed when the valve body is in the closed position and drains the hydraulic oil supplied from the external pressure oil supply means when the valve body is in the communication position. Hydraulic diaphragm type non-pulsation pump featuring:
