A hydraulic actuator arrangement () is described 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. Such an actuator arrangement should have many application possibilities. To this end, a hydraulic pressure amplifier () is arranged between the hydraulic pump () and the pressure chamber ().

Hydraulic actuator arrangement

A hydraulic actuator () is disclosed comprising a cylinder housing (), a piston () with a piston rod () being displaceably arranged inside the cylinder housing () and a pressure amplifier () comprising an inlet section () with a pressure inlet port (), an active section () with a high pressure outlet port (), a low pressure chamber () and a high pressure chamber (). It is an objective of the invention to provide a hydraulic actuator () with a modular pressure amplifier (). To this end, the inlet section () is arranged inside the piston rod (), and wherein the low pressure chamber () is stationarily arranged relative to the inlet section ().

Hydraulic actuator with pressure amplifier

A hydraulic actuator () is disclosed comprising a cylinder housing (), a piston () with a piston rod () being displaceably arranged inside the cylinder housing () and a pressure amplifier () comprising an inlet section () with a pressure inlet port (), an active section () with a high pressure outlet port (), a low pressure chamber () and a high pressure chamber (). It is an objective of the invention to provide a hydraulic actuator () with a modular pressure amplifier (). To this end, the hydraulic actuator () comprises a cartridge pressure amplifier () comprising a sleeve () being arranged at least partially inside the piston rod (), and wherein the pressure amplifier () is stationarily arranged inside the sleeve ().
