Filed: 1992-10-29
Abstract: PURPOSE:To provide a pressure compensating function and a load checking function in an oil pressure control valve device provided with a spool type direction change-over valve, reduce pressure loss, make the device compact, and facilitate its manufacture. CONSTITUTION:An oil pressure control valve device 100 is composed of a direction change-over valve 200, a sheet valve 300, and a pilot control valve 400, and the sheet valve 300 determines the amount of displacement of a sheet valve- disc by the pilot flow rate passing through a control variable throttle. Further, the pilot flow rate is controlled by the pilot control valve 400 in response to the differential pressure across a main variable throttle of the direction change- over valve 200. Thus, a pressure compensating function having an auxiliary flow rate control function for helpfully controlling the flow rate of pressurized oil supplied to the main variable throttle is given to the oil pressure control valve device. Further, the sheet valve has also a load checking function.
