  • Patent number: 9234531
    Abstract: A damping element for attenuating hydraulic pressure pulses is integrated into a hydraulic chamber of a motor vehicle hydraulic system. The damping element includes a end cap support body and a membrane that fits over a portion of the support body. The membrane has a first side facing towards a source of hydraulic fluid and a second side facing away from the hydraulic fluid source. At least one space is provided between the second side of the membrane and the end cap support body to allow for deformation of the membrane under hydraulic pressure. The membrane has a collar with a lip seal provided for fitting into place on the wall of the hydraulic chamber. At least one second space for receiving hydraulic fluid is defined between the lip seal and a region of the membrane opposite the lip seal.

  • Patent number: 9096200
    Abstract: 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.
