<p>PURPOSE:To enable precise pressure control by coupling a feedback pressure receiving chamber and a clutch pack directly to a pilot circuit and controlling a pressure control valve directly. CONSTITUTION:A retainer 25 has a back face facing against a feedback pressure functioning chamber 10 and receives the pressure from the feedback pressure hunctioning chamber 10 in addition to the force of a spring 9. The feedback pressure functioning chamber 10 is coupled through a piping 26 to a clutch pack. When a proportional solenoid 8 functions, a pressure control valve 5 functions to be moved to the right while resisting against the pressing force of the feedback pressure functioning chamber 10. Consequently, the clutch pressure is controlled directly resulting in the precise pressure control.</p> |
