摘要： A method of operating a hydraulic motor (90; 97). In one embodiment, the method includes measuring (115) a temperature of hydraulic fluid associated with the hydraulic motor and comparing (160; 205; 230) the measured temperature of the hydraulic fluid to a first temperature threshold. The method also includes controlling (165; 170; 210; 213; 215; 225; 235) an operational state of one or more hydraulic motor functions based at least partially on the comparison of the measured temperature of the hydraulic fluid and the first temperature threshold.

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).

摘要： A reservoir (112/212) for a hydraulic pump system includes a reservoir body (140/240), an inner wall (144/244) dividing an interior of the reservoir body into a first pressure chamber (148/248) and a second pressure chamber (152/252), and a one-way valve (156/256) connecting the first pressure chamber and the second pressure chamber. A piston assembly (180/280) forms a first cylinder portion (184a/284a) connected to the first pressure chamber and a second cylinder portion (184b/284b) that is vented. The piston is movable within the cylinder under the influence of a biasing member (192/292) to increase and decrease the overall volume of the first pressure chamber. The piston pressures a piston pump inlet (172/272) connected to the first pressure chamber and maintains a constant pressure within the first pressure chamber under a variety of piston pump operating conditions.

摘要： A machine (10) having a hydraulic power management system (105). The machine includes an internal combustion engine (30) driving first and second fixed displacement pumps (95, 100) to produce a combined flow of pressurized fluid. Main (50, 55, 45) and auxiliary (57) implements are operable in response to a flow of pressurized fluid, and a control valve (90) selectively directs the combined flow to the main and auxiliary implements. A power management system (105) is operable to stop the flow of pressurized fluid to the main implement (50, 55, 45) from the second pump (100) when the pressure of the combined flow exceeds a pressure indicative of the impending engine stall. A means for providing the combined flow to the auxiliary implement without regard to the pressure of the combined flow is also provided, and may take the form of a power management override (150) or bypass mechanism (110).
