Hydraulic damping device for hydraulic system of motor vehicle, has damping diaphragm fastened to damping housing using cover, which is arranged on side of damping diaphragm turned away from hydraulic medium pressure chamber
The device (1) has a damping diaphragm (10) limiting a hydraulic medium pressure chamber (4) in a damping housing (2). The diaphragm is fastened to the housing using a cover (15), which is arranged on a side of the diaphragm turned away from the pressure chamber. A sealing element (24) i.e. O-ring, is fixed between the cover and the diaphragm. The cover has a circumferential groove (20) for the sealing element and connected with the housing in a material-fit manner. The cover and the housing are made of plastic, and the diaphragm is made of metal i.e. steel. An independent claim is also included for a hydraulic system comprising a master cylinder.
