摘要： A vehicle braking system includes a slip control system operable in an electronic stability control (ESC) mode to automatically and selectively apply the brakes in an attempt to stabilize the vehicle when an instability condition has been sensed. The slip control system is further operable in an adaptive cruise control (ACC) mode to automatically apply the brakes to slow the vehicle in response to a control signal. The slip control system includes a variable speed motor drive piston pump for supplying pressurized fluid pressure to the brakes through a valve arrangement. In the ESC mode, the pump motor operates in an ESC speed range, and in the ACC mode, the pump motor operates in an ACC speed range lower than the ESC speed range. The slip control system further includes an attenuator connected to a pump outlet for dampening pump output pressure pulses prior to application to the brakes. The attenuator includes an elastomeric member located in an attenuator chamber of a housing. The attenuator chamber defines a shoulder and the elastomeric member includes a flange which rests on the shoulder and locates the elastomeric member in a predetermined axial position within the attenuator chamber. An outside wall of the elastomeric member includes circumferentially extending grooves defining ribs between adjacent grooves.

摘要： A hydraulic system comprising a receiving body with electrohydraulic valve, with at least one hydraulic pump, and with channels for connecting the pump to at least one hydraulic load. A pulsation situation arises as a result of the delivery of a pressure medium by the pump and/or as a result of pressure medium being withdrawn by the load. At least one damping unit is provided, having a plurality of pulsation damping means such as, in particular, a damping chamber, and orifice. The hydraulic system provides a uniform and cost-effective solution for different operating situations and prevents a decrease in comfort. The damping unit has at least one switching means for adjusting the action of said damping unit to a varied pulsation situation by connecting or disconnecting one or more damping means.
