Abstract

PURPOSE: To eliminate any operating failure due to lack of the amount of medium by installing an auxiliary compartment in an operating chamber and by installing on the auxiliary compartment a valve which closes when the volume of medium liquid is short and by connecting the operating chamber to a tank with a feed line provided with a feed check valve.
CONSTITUTION: An operating chamber 4 is provided with an auxiliary compartment 12. The auxiliary compartment 12 is provided with a valve 13 which closes when the amount of medium liquid is short. At the same time, the space 4' of the operating chamber 4 and a tank 16 are connected with a feed line 17 provided with a feed check valve 18 which is opened by the engative pressure in the operating chamber 4. Whenever a negative pressure is produced in space 4' by shortage of the amount of medium, this construction permits a plunger 8 to make a reciprocating feed performance automatically, which prevents troubles due to shortage of the amount of medium.
