Estimating the term…
A hydraulic actuator (1) is disclosed comprising a cylinder housing (2), a piston (5) with a piston rod (6) being displaceably arranged inside the cylinder housing (2) and a pressure amplifier (10) comprising an inlet section (18) with a pressure inlet port (20), an active section (19) with a high pressure outlet port (22), a low pressure chamber (32) and a high pressure chamber (38a). It is an objective of the invention to provide a hydraulic actuator (1) with a modular pressure amplifier (10). To this end, the inlet section (18) is arranged inside the piston rod (6), and wherein the low pressure chamber (32) is stationarily arranged relative to the inlet section (18).
A hydraulic actuator 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, wherein the inlet section is arranged inside the piston rod, wherein the low pressure chamber is stationarily arranged relative to the inlet section, wherein the inlet section comprises a pilot sequence valve being in fluid communication with the pressure inlet port, and wherein the pilot sequence valve is arranged inside the piston rod.
