A short-body connector for fluid couplings made of a sleeve-shaped body. In the sleeve-shaped body an internal thread is provided, by which the connector can be screwed onto a threaded connection. Relative to axial extension, the locking groove and locking rib serving to hold the connector in the coupler are located at the height of the thread. That is, the locking rib and locking groove located ahead of the thread in the state of the art have moved to the region of the thread in the arrangement according to the invention.

An electrical switching system, preferably a medium-voltage switching system, has a power switch or load switch, a disconnecting switch, and a grounding switch configured as a vacuum switching chamber. Low separation distance lengths and a more compact construction of a switching system is achieved by means of a housing in which the disconnecting switch, configured as a vacuum switching chamber, the grounding switch, and the power switch or load switch are disposed, and in which a central switch is disposed, with which the vacuum switching chambers of disconnecting switch and grounding switch can be mechanically activated. Electrical connections between connector contacts of power switch or load switch, disconnecting switch, and grounding switch can be produced.

A belt buckle (10) for a seat belt includes a buckle housing (16), a locking mechanism for locking a plug-in tongue inserted in the buckle housing (16), a release button (22) which is movable in a first direction relative to the buckle housing (16) for unlocking the plug-in tongue, and a safety mechanism for preventing automatic displacement of the release button (22) in the first direction. The safety mechanism includes a mass body (36) movable in the first direction relative to the buckle housing (16) and a movably supported coupling lever (24) including an axis of rotation which is stationary relative to the buckle housing (16). The coupling lever (24) is coupled to the mass body (36) and to the release button (22) so that, upon acceleration of the belt buckle (10) in a second direction opposed to the first direction, it transmits an inertia force acting on the mass body (36) in the first direction to the release button (22) in the opposite second direction.

An axial face seal (13), which seals a pump housing in the region of the pump shaft (12), is constructed in an axially compact manner. Spring holders (24, 25), which transmit the required pressing force of a compression spring (23), are connected to one another with a positive fit in a rotation direction, and hold a rotating axial face seal ring (19) in a rotationally fixed manner to the pump shaft (12). The spring holders (24, 25) are compact and enclose an abutment ring (33) for pump impellers as well as the compression spring (23). A motor-side spring (24) engages over the rotating axial face seal ring (19), by which an axially extremely short constructional length is achieved.

An air spring for a motor vehicle having a rolling bellows filled with gas under pressure, one end of the rolling bellows is connected to a load receiver and the other end is fastened to a roll-off piston′. The load receiver and the roll-off piston are moveable relative to one another depending on a force impinging on the load receiver toward the roll-off piston. A sensor device is arranged inside the rolling bellows by which a distance between the load receiver and the roll-off piston is detected. A pressure piece extending in direction of the roll-off piston is arranged at the load receiver and a sensor body is movably drivable along a sensor track of the sensor device by an end region of the pressure piece facing the roll-off piston. The sensor device generates an electric signal corresponding to the position of the sensor body on the sensor track.
