FLOW COMPENSATED RESTRICTIVE ORIFICE FOR OVERRUNNING LOAD PROTECTION |
摘要 |
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). |
