Motor Running At Constant Speed - Kubota U20-3 Workshop Manual

U20-3, U25-3 WSM Hydraulic system (Mechanism section)

2) Motor running at constant speed

With the motor running at constant speed, the oil passage A stays under high pressure. Thanks to
the action of the check valve C, however, the pressure oil is kept from leaking out toward the low-
pressure side.
Thus the motor runs stably with the anti-cavitation mechanism intact.
