<p>PURPOSE:To lessen occupying area as well as permit free wheeling by introducing rotating torque from engine by using the casing of a liquid pressure pump as a receiving pulley and also by housing auxiliary pump in liquid pressure pump. CONSTITUTION:A stationary pump unit consisting of the cylinder block 19, provided eccentrically with the fixed main axle 13, into which the piston 18 is fitted radially, is enclosed with the both side plates 11 and 12 and casing 1 and sealed. And, oil from the suction oil path 25 is discharged to the discharge oil path 26 as a pressure oil by rotating the periphery of the casing 1 as receiving pulley. On the other hand, the pressure oil is introduced from the suction oil path 27 for free wheeling to the discharge oil path 28 by means of the fixed toothed wheel 22 and the rotary toothed wheel 23. And, the casing 1 is free-wheeled by filling the pressure oil in the casing 1 by providing throttle or switching valve to the discharge oil path 28.</p> |
