摘要: 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 (17) 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 (17).
To this end, the hydraulic actuator (1) comprises a cartridge pressure amplifier (10) comprising a sleeve (10a) being arranged at least partially inside the piston rod (6), and wherein the pressure amplifier (17) is stationarily arranged inside the sleeve (10a).摘要翻译: 本发明公开了一种液压致动器(1),该液压致动器包括缸壳体(2),具有可移位地设置在缸壳体(2)内的活塞杆(6)的活塞(5)和包括入口部分 (20),具有高压出口端口(22),低压腔室(32)和高压腔室(38a)的有源部分(19)。 本发明的目的是提供一种具有模块式压力放大器(17)的液压致动器(1)。 为此,液压致动器(1)包括盒式压力放大器(10),该盒式压力放大器包括至少部分布置在活塞杆(6)内部的套筒(10a),并且其中压力放大器(17)固定地布置在 套筒(10a)。
