Abstract

PURPOSE: To enable to control the output of a pump to be constant, by providing a differential pressure valve in a pressure controlling system, and controlling the discharge rate of a flow control valve automatically.
CONSTITUTION: The differential pressure valve 45 is composed of a poppet valve 45a and a spring 46b, and the differential pressure (Pd-P1) is proportional to the spring force. As Pd is raised, differential pressure valve 45 is set into operation and displacement of a piston 35 is increased. This displacement of the piston 35 is transmitted to a rod 39 via a ball joint 41 which is disposed at the axial center of a spring shoe 36. With such an arrangement, displacement of piston 35 is rendered linear to hydraulic pressure Pd and control characteristics of a compensator 31 is rendered to be proportional. Therefore, it is enabled to control the output of a pump to be constant.
