Abstract
A damping device, for example for damping pressure pulses in a brake circuit of a slip-controllable hydraulic vehicle brake system, includes a damper chamber with a pressure medium volumetric capacity, which can be varied in a pressure-dependent manner, and a flow resistor connected downstream thereof. Disadvantageously, the pressure medium volumetric capacity of the damping device is not available for the brake pressure build-up when the brake pressure is generated by the driver, and the pedal travel on a brake master cylinder of a vehicle brake system is therefore lengthened. A mechanism limits the pressure medium volumetric capacity of the damping device in the case of a passive braking operation. In the case of partially active or fully active braking operations, in contrast, the mechanism has no effect and the full scope of the pressure medium volumetric capacity of the damping device is available for damping pressure pulses.
