  • Publication number: 20080230676
    Abstract: A rubber mounting, in particular for a motor-driven pump unit of a power steering system, the rubber mounting has a holding flange, a bolt which starts to extend from the holding flange, a rubber element disposed on the bolt, and a fastening eye disposed on the rubber element. The bolt is waisted so that a particularly high flexibility of the rubber mounting in the case of movements in a plane perpendicular to the longitudinal axis of the bolt is achieved.

  • Patent number: 5409087
    Abstract: A hydraulic dashpot for motor vehicles. It has a cylinder that accommodates a fluid. A shock-absorbing piston travels back and forth in the cylinder and divides it into two displacement chambers. The piston is connected to a rod that extends through a centering component at one end of the cylinder. A hydraulic decompression-stroke limiter consists of a cup-shaped recess below the rod-centering component and of another piston on the piston rod above the shock-absorbing piston. Channels extend through the stroke-limiting piston and are blocked off in the decompression-stroke direction. The object is a less expensive dashpot. The stroke-limiting piston consists of a thin stroke-limiting disk with a diameter slightly shorter than the critical diameter of the recess and resting on a thicker support.
