Unloading arrangement for hydraulic swing circuit or the like |
摘要 |
A closed loop hydraulic swing circuit is provided with crossover auxiliary actuating connections between the pump control lines and the system relief valves to cause the relief valves to open at lower than maximum system pressure in an unloading action that limits braking when a coasting load is causing the motor to return more fluid than the pump can accept.
