Abstract

PURPOSE: To prevent pressure of the circuit following the flow outlet from rising, by moving upward the main piston and making throttle response of the variable throttle valve slow for increment of the flow rate and by opening the movable throttle valve and making response quick for reduction of the flow rate.
CONSTITUTION: Variable throttle valve 40 which controls the throttle opening according to the passage flow rate of pilot relief valve 32 and has spool 35 pressed by spring 33 is provided for pressure of flow inlet 24. When pressure of flow outlet 24 rises and main piston 22 moves upward due to increment of the flow rate flowed to relief valve 32, variable throttle valve 40 is throttled to make response slow. Meanwhile, when the flow rate flowed to relief valve 32 is reduced or stopped and main piston 22 moves downward, throttle valve 40 is opened to make response quick. As a result, pressure of the circuit following the flow outlet can be prevented from rising by adjusting response of the pilot operating type reducing valve oppositely to the flow rate.
