摘要： A double-acting overflow valve of a working cylinder includes a housing with an encompassing wall and a first and a second axial delimiting wall disposed opposite one another. A first valve body has a first valve tappet with a conical shape and passes through the first axial bore to define a first annular gap with a gap width that is dependent on a position of the first valve body along an actuation path thereof. A second valve body has a second valve tappet with a conical shape and passes through the second axial bore to a second annular gap with a gap width that is dependent on a position of the second valve body along an actuation path thereof. A first and second counter bearing are provided. A first actuating element defines a maximum actuation path of the first valve body by acting on the first counter bearing. A second actuating element defines a maximum actuation path of the second valve body by acting on the second counter bearing. A first spring applies an axial force to the first valve body in a direction of the closed position of the first valve disk. A second spring applies an axial force to the second valve body in a direction of the closed position of the second valve disk.

摘要： The invention relates to a threaded pairing, consisting of the assigned threaded parts, for the transmission of axial forces, where the screw thread (5) is filled with the sealing compound (6). The task is to create an axially positionable threaded pairing capable of being turned, a joint which at the same time is sufficiently rigid (by means of frictionally connected flanks) and leak-proof (by filling the positively fitting screw thread with sealing compound (6)). This task is successfully completed by at least one threaded part (1) consisting, in terms of the length of its axial thread (7), of a cylindrical flanked basic body (8) and a non-cylindrical flanked basic body (9), being screwed together with the assigned threaded part (2) in the axial length section of the non-cylindrical flanked body (9) and thus forming a line-like contact between the opposing flanks (4) at the point of maximal radial difference against the flanked basic body of the assigned threaded part (2) which is under radial tension of the flanks (4). This radial tension ensures that the threaded parts are fixed over a stop-free adjustment area (10) and that both sides of the flanks (4) are embedded into the sealing compound (6) through flank clearance (11).

摘要： A working cylinder which has end-position damping. A piston ring passes over an axially offset pressure medium connection and encloses a pressure medium damping volume. The piston ring includes a ring joint which has a base section and a projection section. The piston ring is of sealing construction. The pressure medium flows out of the pressure medium damping volume via an axial transfer channel, which can be defined by an axial cylinder-tube groove or an axial piston-ring groove. Also, there is a damping piston ring, which is of sealing construction and which has an axial piston-ring groove.

摘要： A piston unit of a working cylinder has first and second coupling partners. The first coupling partner is a piston. The second coupling partner a piston rod. The piston rod is inserted axially into the piston. Each of the coupling partners has an annular groove. The groove of the piston rod is an external groove. The groove of the piston is an internal groove. The grooves of the coupling partners lie opposite one another. The unit has a coupling strand which engages in the grooves of the coupling partners and is placed into engagement by insertion into an annular groove gap defined by the grooves. The engagement of the coupling strand in the grooves produces a form-locking connection between the partners. The piston rod is oversized in relation to the piston and provides an additional frictional connection.

The coupling ring, when deformed in a tensioning direction, is fully accommodated by the groove of one coupling partner and which, when deformed in a release direction, engages in the grooves of both coupling partners.
