  • Publication number: 20230016695
    Abstract: A valve arrangement is inserted between a master brake cylinder and a reservoir in a housing of an electrohydraulic motor vehicle brake system which can be activated both by a vehicle driver and independently of the vehicle driver. The valve arrangement can be acted on by a volume flow which can be conveyed by a linear actuator in the direction of a pedal travel simulator, the working chamber of the pedal travel simulator being connected to the master brake cylinder, wherein, for the purpose of simplified construction and actuation, the valve arrangement has a hydraulically actuable non-return valve and a fixed diaphragm arranged parallel to the non-return valve. The non-return valve is arranged together with the fixed diaphragm in a valve carrier which is fastened to a closure plug which closes the housing of the motor vehicle brake system.

  • Publication number: 20050126297
    Abstract: The present invention relates to a sensor element for detecting pressures or forces. The sensor element (10) includes a sensor diaphragm (13), on the diaphragm outer side (20) of which piezoresistive measuring elements (8) are located. The sensor diaphragm (13) of the sensor element (10) is diametrically opposed to a sealing surface (15, 16) for sealing off the sensor element (10) from a housing. A force introduction region (23, 24) for introducing a force which produces a seal is mechanically decoupled from the sensor diaphragm (13) of the sensor element (10).
