    Abstract: A brake system for motor vehicles, which brake system can be actuated both by the vehicle driver and also independently of the vehicle driver in a “brake by wire” operating mode, is preferentially operated in the “brake by wire” operating mode, and can be operated in at least one fall-back operating mode in which only operation by the vehicle driver is possible. The brake system has inter alia an electrohydraulic pressure generating device (5) which outputs a brake system pressure, and a pressure modulation unit which has one inlet valve (6a-6d) and one outlet valve (7a-7d) per wheel brake (8, 9, 10, 11) for setting wheel-specific brake pressures derived from the brake system pressure, wherein the inlet and outlet valves (6a-6d, 7a-7d) output or transmit the brake system pressure when in the non-actuated state.

    Abstract: A two-tube shock absorber for automotive vehicles is furnished with a shock absorber piston and an electromagnetically actuatable unidirectional shock absorber valve to adjust a "smooth" characteristic which is desired for enhancing driving comfort. The shock absorber valve is alternatively configurated in the shape of a single-stage, or a two-stage slide valve. The position of the slide depends on the hydraulic pressure differential which decreases above the shock absorber valve, the volumetric stream which flows through the shock absorber valve, and the actuating current of the electromagnetic actuating unit. The inventive shock absorber allows the selection of a special characteristic curve out of a family of potential characteristic curves. Simultaneously, the sensitivity of the shock absorber to errors of the electromagnetic actuation is eliminated.
