Abstract: 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).

Abstract: Power management control for a power machine or vehicle is disclosed. In illustrated embodiments, a user interface (130) of the power machine or vehicle includes a power management selection (232) for activating and deactivating power management control. In illustrated embodiments, power management control is implemented through a power management control component (222) based upon feedback from an RPM sensor (224). As disclosed in illustrative embodiments, the power management control component (222) utilizes control methods and characteristics stored in system memory to determine control input to adjust hydrostatic parameters for power management.

Abstract: A valve (100) for regulating the flow of fluid through an access port (106) in a fluid chamber (102) includes a body (110) having a first end (112) and a second end (114), the second end being located in the access port and the first end protruding outside of the access port. An axial bore extends from the first end (112) to the second end (114), an injection fitting (118) is formed at the first end of the body in fluid communication with the axial bore, and the second end of the body includes a selective sealing interface (128). The body (110) forms a sealing interface with a threaded inner wall surface (126) of the access port. A one way valve assembly (136) is positioned within the axial bore, and is arranged to permit a flow of fluid therethrough in a downstream direction and prevent the flow of fluid therethrough in an upstream direction. A bypass passageway (143) extends from the selective sealing interface (128) separate from the axial bore. A connecting passageway (144) connects the bypass passageway (143) with the axial bore upstream of the one-way valve assembly.

Abstract: The present disclosure is directed to a control system (50) for a power machine (10) that provides selected resolution of the adjusted speed control (70) and other controls, such as attachment controls, to provide more options to the operator for fine positioning. The present disclosure includes a control system (50) for a power machine (10). The power machine (10) has a full speed. The control system (50) has an adjustable propulsion controller (92) that an operator can position along a range of movement. Examples of the adjustable propulsion controller (92) that an operator can position along a range of movement.
