摘要： The present invention is related to an electric switch comprising a magnet and a reed contact which is actuatable by the magnetic force of the magnet. The reed contact is shielded relative to the magnetic field of the magnet by means of a bell of magnetic field absorbing material which is furnished with an opening in the switching range of the reed contact to permit switch actuation. Exact switching points at the reed contacts are achieved by this arrangement.

摘要： A pressure control device to be inserted into a connection between a front wheel brake and a rear wheel brake which determines the rear brake hydraulic pressure in dependence upon front brake hydraulic pressure. The pressure control device provides a plurality of valve pistons hydraulically connected in parallel and displaceable by front axle hydraulic pressure in opposition to a control force. A predetermined change-over hydraulic pressure develops a braking pressure in the rear brake which is less than the front brake pressure. The valve pistons are provided by stepped pistons guided within stepped bores, each of which pistons provides smaller and larger effective pressure surfaces.

摘要： A power brake unit for automotive vehicles comprising a valve adapted to meter fluid from an energy source into a booster chamber to act upon a booster piston arrangement. The booster piston arrangement includes a first booster piston and a second booster piston with the second booster piston being inoperative in the event of failure of the energy source. If the energy source fails, the pedal force is directly and mechanically transmitted from the brake pedal to the master cylinder piston via the first booster piston.

摘要： In an auxiliary power assisted master cylinder arrangement for a vehicle brake system to generate a controlled brake pressure in associated wheel brake cylinders, there is provided a brake valve with a preceding servo travel simulator to effect a control of the wheel brake cylinders of a vehicle. In one construction of the arrangement, there is interposed between two master cylinder units a pedal-operable device including mechanical cross links connecting with the master cylinder units as well as another cross link connecting with the brake valve. The brake valve is movable into engagement with the servo travel simulator, while the pedal-operable device, under normal braking conditions, is acted upon by the controlled pressure from an auxiliary power source in opposition to the pedal pressure and includes a lock providing for interlocking of all mechanical links in the event of a failure of auxiliary power. In another construction, each master cylinder unit is preceded by a second lock which is normally released with auxiliary power available and, in the event of a failure of the auxiliary power, couples the master cylinder units with the associated cross links at least in the direction of pedal operation. The present invention is advantageously employed as a brake slip control apparatus.

摘要： A hydraulic booster for a brake system comprising a booster piston, a pressure-control device, an annular piston bearing against the booster piston and a central piston which is movable within limits relative to the annular piston by the brake pedal and actuates the pressure-control device. In this arrangement, the central piston and the annular piston are adapted to be coupled together after the force of a spring is overcome whereupon these two pistons are movable as one. The central piston is permanently subjected to the pressure acting on the booster piston when the brake system is actuated.
