PRESSURE COMPENSATION VALVE

摘要

A pressure compensation valve capable of distributing an output hydraulic pressure from a single hydraulic pressure supply source to a plurality of hydraulic pressure loads without using a shuttel valve, wherein a valve for establishing and shutting off communication between inlet and outlet ports is provided in a valve body to form a check valve portion, and a spool for establishing communication between second and third ports by the pressure in a first pressure chamber which communicates with a first port, and shutting off the communication between the second and third ports by the pressure in a second pressure chamber communicating with the third ports is also provided in the same valve body to form a reducing valve portion, the spool being urged by a spring in the direction in which the second and third ports are shut off from each other, to be brought into contact with the valve.
