ABSTRACT:
A clutch pressure control valve for a hydraulically actuated friction clutch which includes a valve spool 5 disposed within a valve bore and having two control collars 6 and 7. The spool is acted upon at one end by a linear compression spring 8 and a speed dependent pressure signal, the spool serving to regulate the clutch pressure by regulating the free cross section at an outlet port disposed between its control collars. To avoid the second order variation of the clutch pressure with speed, the control collars 6 and 7 of the valve spool 5 have two different diameters and the spool 5 is disposed within a stepped bore 2, 3 and 4. The end of the linear compression spring 8, remote from the valve spool 5, abuts a reaction piston 9, which is disposed within the valve bore and is acted upon on one side by the speed dependent pressure signal and on the other side by a second, non-linear compression spring 11, which is compressed between the reaction 9 and a shoulder 12 in the valve bore.
