Abstract

PURPOSE: To prevent cyclic velocity changes of an actuator by providing a compensating element to inhale and exhale in commensuration to pressure changes of the actuator in a line to link between a pilot chamber of a pressure compensating valve and an antecedent position of the actuator.
CONSTITUTION: When pressure of main current fluid 37 has been aggrandized, fluid pushed out of a chamber on the left side of a cylinder 30 is worked into a spool 23, and a pilot chamber 26 at the left extremity, which pushes said spool 23 in the right direction, pressure rise of the main current fluid 37 is repressed, to the contrary, when the pressure of the main current fluid 37 has been dropped, right movement of a piston 32 by a spring 33 reduces the pressure in the pilot chamber 26, left movement of the spool 23 prevents larger reduction of the pressure of the main current fluid 37. In consequence, width of pressure changes of the main current fluid 37 becomes smaller, to be able to prevent cyclic velocity changes of the first actuator 21.
