用于过载保护的流量补偿限制孔
摘要：
一种用于致动器(18)的液压回路(44，52，60)，致动器包括活塞(64)和在第一方向上移动负载并能够在相反方向被从外部加载的活塞杆(65)。液压回路包括在致动器和控制阀(52)之间的流量补偿阀(60)。当致动器(18)中的活塞(65)在外部负载状态下在第二相反方向上移动并且通过流量补偿阀(60)流出致动器(18)的流体的流动速度超出选定速度时，设在流动路径上的限制孔(62)限制从致动器(18)流出的流体。
摘要（英）：

A hydraulic circuit (44, 52, 60) for an actuator 18) that has a piston (64) and piston rod (65) that will move a load in a first direction, and which can be externally loaded in an opposite direction, includes a flow compensated valve (60) between the actuator and a control valve (52). When the piston (65) in the actuator (18) is moved in the second opposite direction under the external load and the rate of flow of fluid out of the actuator (18) through the flow compensated valve (60) exceeds a selected rate, an orifice (62) is in the flow path restricts flow from the actuator (18).
