摘要： A linear actuator system includes a linear actuator and an integrated pump assembly connected to the linear actuator to provide fluid to operate the linear actuator. The integrated pump assembly includes a pump with two fluid drivers, each fluid driver comprising a prime mover and a fluid displacement assembly to be driven by the prime mover such that fluid is transferred from a first port of the pump to a second port of the pump. The pump assembly also includes two valve assembles to isolate the pump from the system. The linear actuator system also includes a controller that establishes the pump in a normal mode of operation in which the prime movers are independently driven and switches to a fail-safe mode of operation in which only one prime mover is operated.

摘要： The present invention relates to an intelligent load-sensing EHA comprising a variable displacement hydraulic pump, a symmetrical hydraulic cylinder, a feedback module, a pressure-following valve and an execution mechanism. The symmetrical hydraulic cylinder includes a symmetrical plunger, a first cylinder and a second cylinder separated by the plunger. The variable displacement hydraulic pump includes an oil inlet and an oil outlet. An output of the feedback module is used to output a greater one of the pressures at the first input and the second input to the execution mechanism. The pressure-following valve is connected between the output of the feedback module and an input end of the execution mechanism to reduce an instantaneous flow input to the input end of the execution mechanism and adjust the pressure at the input end of the execution mechanism. The execution mechanism is used to receive an output of the feedback module and generate a signal for changing a displacement of the variable displacement hydraulic pump. Thanks to the intelligent load-sensing EHA of the present invention, the displacement of the variable displacement hydraulic pump can be adjusted quantitatively by controlling an output pressure of the pressure-following valve to reduce radiation and energy consumption of the entire system.
