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 screw-threaded working cylinder includes a tubular cylinder that an end region. The end region has a first thread. The end region has a tapered wall section and the tapered wall section has an axial annular surface. A closure has a second thread and the closure is screwed by the second thread into the first thread in a final mounting position. The closure has a mating axial annular surface. The axial annular surface and the mating axial annular surface are pressed in a positive fitting contact to one another in the final mounting position for defining a pressure contact surface. The pressure contact surface defines a sealing plane, and a surface pressure in an area of the pressure contact surface that causes a deformation of the tubular cylinder and the closure. The deformation occurs within an elastic limit over a range from zero applied pressure to a maximum permissible pressure by a pressure medium for the working cylinder. A piston unit is accommodated in the tubular cylinder.

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 is 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 spring-loaded coupling ring. 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. The engagement of the coupling ring 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.

摘要： An end dampened working cylinder for a fluid which serves as a fluid power medium for transmission of energy, the working cylinder comprising a main piston; control plungers carrying ring magnets and mounted on both sides of the main piston; springs form-locking the control plungers with the main piston and piston rod; sensors incorporated in a topside end and a bottom end and reacting to a contactless magnetic field, so that on approaching the ring magnet but at least on reaching a sealing rest position of the control plunger at each of the end stops a signal of a respective one of the sensors is generated and serves for controlling the fluid power, the control plungers sliding along the piston rod so as to provide adjustable and guaranteed sealing, outlet channels and a throttled flow-off channel, the control plungers serving as a shut-off component and valve for the outlet channels, so that when the control plungers rest on the topside end and the bottom end a dampening space is formed, from which a dampened fluid outlet through the throttled flow-off channel provides an external means of adjustment in form of a throttle adjustment screw.
