<p>PURPOSE:To simplify piping, decrease energy loss, facilitate timing setting, and improve control accuracy, etc., in an operational circuit of an oil hydraulic clutch. CONSTITUTION:A piston 15 is rapidly transferred from a transferring end on the port F side to the transferring end on the port G side following to clutch connection operation, and pressure oil of a large flow rate is pressure-fed according to transfer of position and the oil hydraulic clutch is operated at a high speed to its connection starting position, and thereafter, the pressure oil of a small flow rate is pressure-fed via the throttle hole 16a of a check valve 16 so as to interpose a boost valve 13 for operating the oil hydraulic clutch from the connection starting position to a complete connection position at a low speed, between a reducing pressure separation valve and the hydraulic clutch.</p> |
