A pressure control device for an anti-lock and/or anti-slip system of a motor vehicle comprises a valve casing (10) in which a damping chamber (36) and an expansion chamber (44) are arranged in a common recess (12, 12'), the two chambers having a common axis. A pump is disposed in an adjacent recess having an axis parallel to the common axis of the chambers whereby substantial space is saved over prior arrangements.

Pressure control device for an anti-lock and/or anti-slip system

A first control valve which is normally open connects a master cylinder connection to a wheel cylinder connection. A second control valve which is normally closed connects the wheel cylinder connection to a storing chamber for returning brake fluid and to an inlet passage of a return pump when it is in open position. The return pump communicates through an output passage with a damping chamber. The damping chamber is arranged in a valve receptacle for the first control valve, and the storing compartment is arranged in a valve receptacle for the second control valve.

Pressure control device for anti-lock or anti-skid systems in motor

In an anti-lock brake system (ABS) for a motorcycle the driving stabilty is improved by measuring the position of lateral inclination of the motorcycle and adjusting at least one threshold value for the anti-skid control in response to the measurement. In another embodiment the transverse acceleration of the motor cycle is measured and an ABS threshold value adjusted accordingly.
