Abstract
PURPOSE:To achieve quick and reliable coupling/blocking operation by employing a spring load differential piston type poppet valve and integrally constituting a pilot operation poppet valve which employs the small diameter tip portion of the valve body as pilot piston. CONSTITUTION:Upon opening of any one of solenoid or manual valve V1, V2, pressure oil is fed from a hydraulic pump P into a primary valve chamber 16 at large diameter side, then fed through a throttle communication hole 20 into a back pressure chamber 18 at large diameter side and returned through the solenoid or manual valve V1 or V2 into a storage tank T. Consequently, a spring load differential piston type poppet valve 10 is opened to feed pressure oil through a clutch port 24 to a hydraulic clutch 50. Upon closure of the solenoid and manual valves V1, V2, pressure in the back pressure chamber 18 at large diameter side increases to close the poppet valve 10, while simultaneously, a spherical poppet valve body 31 is pushed to open a pilot operation type poppet valve 30 so as to discharge pressure oil from the hydraulic clutch 50 into the oil storage tank T.
