    • A hydraulic linear drive, particularly a hydraulic transmission actuator, having a piston/cylinder unit, in which an actuating piston longitudinally displaceably arranged in the cylinder housing divided into at least two pressure chambers which can be acted upon by hydraulic oil by way of control conduits. A piston rod is connected with the actuating piston, and a sealing element is arranged on the actuating piston to seal off the two pressure chambers from one another. The actuating piston has a two-piece construction and consists of a first and a second piston part between whose facing faces, a sealing element is arranged.

    • A hydraulic linear drive, in particular for a hydraulic transmission actuator, has a piston/cylinder unit in which an adjusting piston is situated so that it is longitudinally displaceable in a cylinder housing and divides a cylinder space into at least two pressure spaces. The pressure spaces can be acted upon by hydraulic oil via controllable pressure supply through hydraulic lines. A sealing ring is situated on the adjusting piston or on the cylinder housing for sealing, the two pressure spaces with respect to one another. The sealing ring is accommodated in a ring groove on the cylinder housing so as to seal with its inside against the adjusting piston. A sealing pressure supply system communicates hydraulic oil to the outside of the sealing ring so as to control the sealing pressure of the sealing ring on the piston surface.
    • 特别是用于液压传动致动器的液压线性驱动器具有活塞/缸单元,其中调节活塞位于其中,使得其可在气缸壳体中纵向移位,并将气缸空间分成至少两个压力空间。 压力空间可以通过液压油通过液压管路的可控供压作用。 密封环位于调节活塞或气缸壳体上,用于密封两个相对于彼此的压力空间。 密封环容纳在气缸壳体上的环形槽中,以便将其与其内部密封抵靠调节活塞。 密封压力供给系统将液压油与密封环的外部连通,以控制活塞表面上的密封环的密封压力。
