Abstract

PURPOSE: To reduce stating torque of a motor by mounting a spring having urging force corresponding to a half of total sum of discharge pressure load and suction pressre load applied to a diaphragm.
CONSTITUTION: A compression spring 11 having in the middle of the reciprocating stroke a force corresponding to a half of total sum of loads which apply discharge pressure (+) and suction pressure (-) of a pump to the effective area of a diaphragm 10 in the opposite directions is urged to oppose said load. When the diaphragm 10 is operated to move to the compression side in a pump pressure chamber 15, it is operated by halved force with the aid of the force of said urged spring 11. On the other hand, when the diaphragm is pulled up, it can be operated with the pullingup force corresponding to the force of said urged spring 11, resulting in the operation of the diaphragm 10 with a uniform drive force for the reciprocation of the diaphragm 10 to reduce the starting torque of a motor.
