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.

A hydraulic brake system for a vehicle for braking the vehicle by brake pedal actuation and/or automatic braking. A pump is provided which has a suction connection that communicates with a supply container for a pressure fluid and a pressure connection for aspirating pressure fluid from the supply container and pumping the fluid to a connection of a master cylinder. A brake circuit of the vehicle brake system is connected with vehicle wheels associated with wheel brake cylinders and with valve assemblies for brake pressure modulation and is connected to the connection of the master cylinder. A valve pressure is also provided between a pressure chamber that communicates with the connection of the master cylinder and the supply container for pressure fluid. The pressure valve is actuatable by pump pressure in automatic braking, which at low pump pressure throttles the fluid flow through the pressure chamber of the master cylinder to the supply container and which limits this pressure at pump pressure that is elevated in comparison.

A magnetic valve that switches at high differential pressures and furnishes a large flow cross section. The magnetic valve has an armature, which when current is supplied to a coil is movable toward a pole core counter to the force of a restoring spring. The armature is capable of opening an auxiliary valve of small sealing diameter directly and a main valve of large sealing diameter indirectly. The auxiliary valve and the main valve have a common closing body, which is movable relative to the armature with a limited stroke. The auxiliary valve communicates through a bore of the closing body with the outflow side of the magnetic valve. In the open position of the magnetic valve, the closing body is held in a position that blocks the auxiliary valve by the action of the second restoring spring. The magnetic valve is suitable in particular for slip-controlled hydraulic brake systems of motor vehicles.

The invention relates to a hydraulic unit for a vehicle brake system with ABS. Before being filled with brake fluid, the brake system must be evacuated in order to achieve complete bleeding. In order to evacuate a return line, which is separated from a brake line by pressure reduction magnet valves that are closed in their position of repose, it is known to provide a connecting line with a check valve between the brake line and the return line. The hydraulic unit connects the check valves in parallel to the magnet valves and integrates the check valves with the magnet valves. This simplifies assembly. Since no additional holes and conduits in the hydraulic unit are necessary, existing hydraulic units can be used.

Electromagnetically controllable valve arrangement

A magnetic valve that furnishes a large flow cross section and switches at high differential pressures. The magnetic valve has an armature, which when current is supplied to a coil is movable toward a pole core counter to the force of a first restoring spring. Guided on the armature is a valve closing member, movable longitudinally relative to the armature, of a seat valve. Also supported in the armature is a second restoring spring, which exerts a force acting in the direction of the pole core upon the valve closing member. The magnetic valve is especially suitable for slip-controlled hydraulic brake systems of motor vehicles.

A space-saving vibration damper that functions reliably for a long term. The vibration damper has a housing that includes at least one concave recess which is sealed by a disk-shaped diaphragm comprising a spring steel sheet. The diaphragm is connected by its edge to a planar surface of the housing by means of material-to-material bonding. The housing has, at the edge of the recess, a rounding that changes over continuously into both the recess and the planar housing surface toward the diaphragm. The hollow chamber disposed between the diaphragm and the recess is filled with air. The vibration damper is designed for use in slip-controlled hydraulic brake systems for a vehicle.

Hydraulic unit for traction-controlled motor vehicle brake systems

An electromagnetically controllable valve has among other elements a guide sleeve that protrudes into a valve block, with an armature and a closing member movable inside the guide sleeve relative to a valve seat. The guide sleeve extends through a securing flange, which is inserted into a receiving bore, located on the valve block, and is fixed there. To secure the guide sleeve against shifting out of the valve block and the securing flange, the guide sleeve is provided with a radially outward-oriented bead. This bead extends within a region, for example an annular recess, that is associated with the securing flange. By way of the recess and the bead, the guide sleeve is axially fixed essentially form-lockingly and inexpensively. The electromagnetically actuatable valve can be built into traction-controlled brake systems of motor vehicles in order to vary brake pressures in the anti-lock and/or traction control modes.

Electromagnetically actuatable valve for a hydraulic brake system

A known electromagnetically actuatable valve has a tubular housing sleeve, a through opening radially penetrating the housing sleeve, and inside the housing sleeve, a valve body having a valve seat and an associated movable valve closing member, and a throttle, which comprises a throttle body and a throttle insert built into it having a throttle restriction, which is embodied as a throttle bore. The throttle body is slipped on like a cap over an open end of the housing sleeve. The throttle of this kind, embodied in a complex manner, is expensive and demands an inordinate amount of installation space. To reduce expense and save installation space, the throttle body along with its throttle insert is omitted and the function of the throttle bore is taken on by the through opening, the through opening is embodied as narrow opening in accordance with the throttle function to be produced. The valve can be used in antilock devices of hydraulic brake systems for motor vehicles.
