A device for contacting an electrically operated apparatus, having at least one terminal contact on the apparatus and one plug that can be connected to it axially, with the plug including a sleeve contact which is in contact with an electrically conducting contact area of the terminal contact after joining them, with the terminal contact being oriented parallel to an installation direction of the apparatus, and the sleeve contact being connectable to the terminal contact parallel to the installation direction.

An anti-lock device for a hydraulic automobile brake system includes a housing block for receiving an eccentric directional valves, two coaxially oriented pump pistons and first and second storage chambers. So that the housing block can be made narrower, the longitudinal axes (F, G, I, J) are distributed to the corners of a quadrangle. At the same time, the common longitudinal axis (E) of the pump pistons can be located between the longitudinal axes of the storage chambers.

Anti-lock device for a hydraulic vehicle brake system

A unit comprising a drive motor and a radial piston pump is proposed, in which unit an armature of the drive motor and an eccentric of the radial piston pup are carried by a common unitary shaft which has three bearings. A three-bearing mounting, known from the prior art, for a shaft of this kind consists of three ball bearings, which are expensive. The invention proposes to replace the ball bearing situated at the greatest distance from the eccentric in the prior art by a slide bearing, and to design the latter as a sintered metal bearing and to impregnate it with a viscous lubricant. The unit according to the invention can be used as a component of an anti-lock device of a vehicle brake installation or of a drive-slip control device acting on driven wheels.

In a known anti-skid control system having a brake booster, a servo piston is followed in the actuating direction by a restoring piston. After a partial stroke, the servo piston can reach the restoring piston and displace it. This arrangement is disadvantageously long. In the brake booster proposed here, a restoring piston is displaceably disposed inside the guide bore. This piston has a bottom and bordering on its a cylinder wall open toward the brake pedal. This wall forms a cylinder jacket in which the servo piston is displaceable. The servo piston executes a part of its working stroke at a variable distance from the bottom of the restoring piston. From the time of contact with the restoring piston, the servo piston executes a further working stroke together with the restoring piston, if necessary.

The invention relates to a brake device for a hydraulic vehicle brake system. In this device, a return feed pump located in a feed pump housing is supported at several points between an assembly housing and a fastening plate and is movable relative to the other components. The mounting is done by screws resting in bearing tubes, the screws being surrounded by elastic damping sleeves in order to enable the elastic mobility of the feed pump housing. The line connections between the feed pump housing and the assembly housing are made by small connecting tubes resting in housing bores in the feed pump housing on one side and in the assembly housing on the other. The through bore extending through the feed pump housing in this region is sealed off on the side of the feed pump housing opposite the small connecting tubes by bolts, which with their part remote from the feed pump housing rest on the fastening plate.

Brake device for a hydraulic vehicle brake system

A brake booster in which a servo piston is slidably supported in a housing. The transmission of a brake force is effected via a piston rod protruding into the housing, and a work chamber is formed between the piston rod and the servo piston. After the opening of a valve, this work chamber can be filled with brake fluid from a reservoir or supply container via a pump or the like. A return line also leads out of the work chamber back to the supply container, via a further valve. To improve the closing or sealing behavior of the valves, the first valve is to be embodied for admitting the brake fluid from a valve cone, or its shoulder, the valve cone extending axially in a blind bore of the servo piston, and a valve seat formed out of a valve bushing. The second valve is likewise embodied as a seat valve, and an element connected with the valve cone cooperates with an element connected with the piston rod.
