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.

摘要： A working cylinder has a cylinder tube, a first closure part, a second closure part and a piston unit. The first closure part is arranged on a first cylinder tube end, the second closure part is arranged on a second cylinder tube end to define a cylinder interior. The piston unit defines at least one working chamber in the cylinder interior. The piston unit slides through the first closure part. The first closure part is joined to the cylinder tube by a first peripheral laser ring weld seam and the second closure part is joined to the cylinder tube by a second peripheral laser ring weld seam. The laser ring weld seams each define a fluid-tight sealing plane. A method for producing the working cylinder is provided.

摘要： A cylinder has first and second coupling partners. The first coupling partner is a cylindrical tube. The second coupling partner is a closing element. One coupling partner is inserted axially into the other coupling partner. Each of the coupling partners has an annular groove. The groove of the inserted coupling partner is an external groove. The groove of the remaining coupling partner is an internal groove and the grooves of the coupling partners lie opposite one another. The working cylinder includes a spring-loaded coupling ring, and which when deformed in a tensioning direction, can be fully accommodated by the groove of one coupling partner and which, when deformed in the release direction, engages in the grooves of both coupling partners. The inserted coupling partner is oversized in relation to the remaining coupling partner and provides a additional frictional connection.

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.
