Abstract

PURPOSE: To provide a hydraulic pressure controlling system for hydraulically operated apparauts, which is capable of controlling hydraulic pressure in an accumulator automatically and correctly by comparing the hydraulic pressure in accumulator and a reference pressure, opening and closing an electromagnetic valve on the basis of the result of this comparison, and thereby establishing and interrupting communication of hydraulic pressure to the accumulator.
CONSTITUTION: Hydraulic pressure in accumulator 21 is detected by pressure sensor 24 and output of the sensor 24 is afforded to comparator 23, in which the signal from sensor 24 is compared with a reference signal afforded from potentiometer 25. If hydraulic pressure in accumulator 21 is lower than the reference value, electromagnetic valve 22 is opened to supply hydraulic fluid from pressure source 10 into accumulator 5, so that hydraulic pressure in accumulator 5 is maintained at a required level. Thus, it is enabled to control the hydraulic pressure in accumulator 5 automatically and correctly at a required level suited for operating hydraulically operated apparatus.
