摘要： The sensor described in the specification and which compares the rotary wheel deceleration with the linear vehicle deceleration, comprises a mass which is subject to both decelerations and whose movement is checked by an electrical sensing means rotating with the shaft. This sensing means provides data signals in the case of an excessive difference between the two decelerations without the need of a mechanical contact between the sensing means and the mass. The description further shows sensors which measure completely non-contacting and which transmit the data signals without the use of slip rings. These sensors can also measure the angular wheel deceleration and simultaneously the transversal deceleration of a vehicle.

摘要： The invention relates to an anti-skid brake system for vehicles. The system shows a new-type sensor and a new brake pressure control device which is activated by the sensor when and for as long as is required. If necessary, the pressure control device produces brake pressure pulsations so that the vehicle's wheels will be intermittently braked. The amplitudes of these pulsations control a special pressure regulating valve depending upon the braking force being applied.The shown sensor controls and compares by electrical means the wheel angular deceleration with the vehicle linear deceleration and provides data signals when the decelerations deviate inadmissibly from one another.

摘要： A piston pump with a controllable stroke is described. It is a positive displacement type pump with several stages and also a continuous variable stroke. The pump piston is only effectively connected with the drive during the working stroke. For example, the pump serves particularly for controlling the braking force in an anti-locking system for vehicles. In every pump cycle it can vary the volume in the braking system, and thus the brake force, without letting fluid out of the brake system. It makes possible the amplitude control of brake pressure pulsations and a desirable brake pressure course. In addition, an anti-locking system with a special two-stage pump device is described. Furthermore, a hydraulic circuit of great utility for anti-locking systems is shown.
