Title:
HYDRAULIC CONTROL VALVE
Document Type and Number:
Japanese Patent JPS5877905
Kind Code:
A
Abstract:
The invention relates to hydraulic control valve controlled by means of a solenoid (24) for the purpose of regulating the supply of fluid to a load such as hydraulic motor. The valve has a valve spool (120) moved by the solenoid (24) and additionally acted upon by the differential pressure across a throttle (42) in the hydraulic circuit so as to provide compensation for the effects of varying viscosity and varying load on the motor. Additionally, to enable a simple design of solenoid (24) to be adopted, a transducer (54) electrically measures the flow rate of hydraulic fluid and varies the current supplied to the solenoid (24) accordingly.
