摘要： A linear actuator system includes a linear actuator and at least one proportional control valve and at least one pump connected to the linear actuator to provide fluid to operate the linear actuator. The at least one pump includes at least one fluid driver having a prime mover and a fluid displacement assembly to be driven by the prime mover such that fluid is transferred from the pump inlet to the pump outlet. The linear actuator system also includes a controller that establishes at least one of a speed and a torque of the at least one prime mover and concurrently establishes an opening of the at least one proportional control valve to adjust at least one of a flow and a pressure in the linear actuator system to an operational set point.

摘要： A hydraulic system control unit, a hydraulic system and a working machine for controlling a hydraulic system adapted to perform at least one hydraulic work function in a working machine are provided. The hydraulic system performs the hydraulic control function in accordance with an operation signal determined by a hydraulic system control unit. In a first step the control unit receives an operator control input associated to the work function. In a second step the control unit receives a load input indicative of a load associated to the work function. Moreover, in a third step the control unit determines the operation signal in response to the operator control input and the load input.

摘要： A hydraulic control assembly, in particular for controlling hydraulic consumers of a mobile machine, includes a load reporting line (26) that can be subjected to the highest load pressure of a plurality of hydraulic consumers, triggered simultaneously each via a respective main control valve (38, 57), and that is connectable by an end portion (26a) to a pump regulator (25). A pressure limiting valve (50) limits the control pressure in the end portion (26a) of the load reporting line (26). The pressure limiting valve (50) is adjustable as a function of the magnitude of a pilot control signal serving to trigger a main control valve (38, 57).
