Abstract
A hydraulic actuator arrangement (1) is described comprising a hydraulic actuator having a pressure chamber (2), a cylinder (3) in a cylinder housing (4), and a piston (5) connected to a piston rod, a hydraulic pump (7) connected to the pressure chamber (2) and an electric motor (8) driving the hydraulic pump (7), wherein the pump (7) and the motor (8) are arranged within the actuator. Such an actuator arrangement should have many application possibilities. To this end, a hydraulic pressure amplifier (10) is arranged between the hydraulic pump (7) and the pressure chamber (2).
Claims22
A hydraulic actuator arrangement comprising a hydraulic actuator having a pressure chamber, a cylinder in a cylinder housing, and a piston connected to a piston rod, a hydraulic pump connected to the pressure chamber, and an electric motor driving the hydraulic pump, wherein the pump and the motor are arranged within the actuator, wherein a hydraulic pressure amplifier is arranged within the hydraulic actuator between the hydraulic pump and the pressure chamber, and wherein the hydraulic pressure amplifier is a pressure amplifier cartridge.
A hydraulic actuator arrangement comprising a hydraulic actuator having a pressure chamber, a cylinder in a cylinder housing, and a piston connected to a piston rod, a hydraulic pump connected to the pressure chamber, and an electric motor driving the hydraulic pump, wherein the pump and the motor are arranged within the actuator, wherein a hydraulic pressure amplifier is arranged within the hydraulic actuator between the hydraulic pump and the pressure chamber, and wherein the motor is arranged in a section of the piston rod extending out of the cylinder in an extracted state of the piston rod.
