Abstract

PURPOSE: To perform a continuous operation without damaging a flexible compartment wall by providing an auxiliary compartment wall in an operating chamber where a plunger makes a reciprocating motion and by installing a valve, which is usually kept open with a spring, in the auxiliary compartment wall.
CONSTITUTION: An auxiliary compartment wall 12 is provided in an operating chamber 4 where a plunger makes a reciprocating motion. A valve 13, which is usually kept open with a spring, is installed in the auxiliary compartment wall 12. With this construction, if a medium liquid leaks slightly and a flexible compartment wall is going to be abnormally extended, the valve 13 operates and closes a liquid nozzle 11, thereby allowing constantly operation without damaging the flexible compartment wall 3.
