Abstract

PURPOSE: To make a static level of load pressure of the actuator equalized in each system, by providing a pressure difference converter, for concerting a load pressure of the actuator into an electric signal of negative polarity to transmit, and a low- pass filter, for transmitting a low frequency component signal of the signals from the pressure difference converter.
CONSTITUTION: A pressure difference converter 6, for converting a detected load pressure of an actuator 4 into an electric signal of negative polarity to transmit, and a low-pass filter 7, for transmitting a low frequency component electric signal of the transmitted signals from the pressure difference converter 6, are provided, with these transmitted electric signals fed back to an adder 1. In such way, even if an output piston of the actuator 4 is coupled to the load by using a link of high rigidity, it becomes capable to equalize a static level of load pressure (pressure difference between both sides of output piston) of the actuator 4 is each system.
