Abstract: A fluid-filled piston cylinder unit comprises a housing with a longitudinal axis and with an interior, a piston rod guided out from the housing in a sealing manner, which can be displaced along the longitudinal axis, as well as a piston connected to the piston rod, which divides the interior into a first sub-interior and a second sub-interior. The piston has a first fluid channel and a second fluid channel in each case for a fluid flow between the first sub-interior and the second sub-interior. The piston has a piston valve for closing the first fluid channel, whereby the piston valve in dependence of a fluid pressure opens the first fluid channel.

Abstract: Method for producing an electrically conductive connection between a component (1), which is positioned in a housing, is equipped with electrical contacts and is accessible from the outside through an opening located in a wall of the housing, and a feed source, using a plug-type element (6), which is equipped with electrical mating contacts (7) and is fitted to the end of an electrical line, which is connected to the feed source and has at least two insulated conductors (8). The plug-type element (6)together with conductors (8) connected thereto is first fixed on one end of a holder (9) made from plastic, whose outer dimensions are smaller than the clear width of the opening (4) of the housing (3). Then the plug-type element (6) is passed through the opening (4) of the housing (3) by means of the holder (9) and is plugged onto the contacts (2) of the component (1).

Abstract: A length-adjustable piston cylinder unit comprises a casing; a guide and sealing unit; a piston rod; a piston; a first interior portion; a second interior portion which faces away from the first interior portion; an adjustment valve; a guide sleeve which is arranged for displacement on the casing, the guide sleeve being secured to the piston rod at a sleeve end and comprising at least one latch opening which is spaced from the sleeve end along the central longitudinal axis; and a latch sleeve arranged on the guide sleeve, the latch sleeve comprising a latch protrusion for engagement into the latch opening, with the latch protrusion of the latch sleeve being arrangeMc in the latch opening of the guide sleeve for arranging the piston cylinder unit in a secured position so that the displaccability of the guide sleeve connected with the piston rod relative to the casing is blocked.

Abstract: A length-adjustable piston cylinder unit comprises a casing which is filled with a fluid and has a central longitudinal axis; a guide and sealing unit which seals off the casing at a first end; a piston rod which is guided through the guide and sealing unit out of the first end of the casing in a sealed manner; a piston which is connected with the piston rod and is guided in the casing in a sealed manner; a first interior portion which is bounded between the piston and the guide and sealing unit; a second interior portion which is bounded by the piston and faces away from the first interior portion; an adjustment valve arranged in the piston for optionally connecting the two interior portions to each other; a guide sleeve which is arranged for displacement on the casing and is concentric to the central longitudinal axis, the guide sleeve being secured to the piston rod at a sleeve end and comprising at least one latch opening which is spaced from the sleeve end along the central longitudinal axis; and a latch
