A valve arrangement arranged in a flow connection between a storage chamber and an operating chamber is actuated by means of an electromagnetic actuating device and, depending on an input rotational movement to a closure element, controls a fluid flow from the storage chamber into the operating chamber. Rotational movement is provided by a rotary armature arranged immediately next to an electromagnet and fixed to a common shaft with the closure element. The magnetic flux path of the electromagnetic actuating device is shortened and thus the efficiency of the arrangement is increased significantly.

A fluid clutch includes a first transmission element and a second transmission element which is rotatable about an axis of rotation with respect to the first transmission element. Torque transmission surfaces of the first and the second transmission elements are located opposite one another in a working fluid region in which torque transmission coupling can be made selectively between the first and the second transmission elements by means of fluid. A valve arrangement can be actuated for selectively making and breaking a fluid flow connection between a fluid storage region and the working fluid region, in order respectively to allow and prevent the ingress of fluid from the fluid storage region into the working fluid region and a braking apparatus can generate a braking force acting on the second transmission element. Two components are movable with respect to one another within a limited range of movement by the transmission of braking force to the second transmission element. As a result of relative movement between the two components, the valve arrangement is actuated for selectively making or breaking the fluid flow connection.

The locking drive for a central locking system of a motor vehicle comprises a support which carries an electric motor, the direction of rotation of which is reversible. Guided for movement on the support are two force-transmitting parts of a gear mechanism which transmits the locking forces, a first force-locking part being adapted to be driven by the electric motor while a second force-locking part can be driven manually, for example by means of a mechanical lock. The second force-transmitting part can be locked at least in one of its extreme positions and relative to the support by means of a locking member. The locking member is controlled via the first force-transmitting part which, for this purpose, is coupled via a dead travel coupling having given clearance to the second force-transmitting part. The locking drive is in particular suitable for the locking of a trunk lock of the motor vehicle so that the trunk lock can be opened when the central locking system is locked without having to unlock the system again in order to perform this function.

The drive device for a locking mechanism of a motor vehicle door lock which can be fastened by means of a central locking installation comprises an operating element which is guided on a housing for linear displacement between a fastening position and an unfastening position and is coupled with the fastening mechanism. A motor drives the operating element in both directions of displacement. A locking lever mounted on the housing for pivoting about a spindle extending transversely of the direction of displacement of the operating element in its locking position blocks the operating element when it is situated in the fastening position. Thus the fastening mechanism in the locked condition cannot be unfastened manually. The locking lever is pivoted by a rotating drive through an eccentric. The eccentric engages in an aperture of the locking lever. The aperture permits a pivoting movement of the eccentric of more than 180.degree., while a stop face of the aperture limits the range of rotation of the eccentric. The end positions of the eccentric are situated, both in the locking position and in the unlocking position of the locking lever in a "beyond-dead-point-position", so that the locking device holds the locking lever in self-locking manner.

A carbon brush with a disconnection apparatus in a cavity in a brush body includes a disconnection body and a prestressed compression-spring body. The disconnection body consists of an electrically insulating material, and the prestressed compression-spring body is configured to act resiliently on the disconnection body. The compression-spring body is formed together with the disconnection body as a short component with a short axial length. In one embodiment, the compression-spring body is in the form of a spring with a plurality of spring turns which, at least in the prestressed, compressed state, are at least partially located one inside the other, shortening them.
