摘要:
The invention relates to a molded piston, in particular an injection-molded piston (1) of fiber-reinforced plastic, which is seated slidably in a receiving bore (2) of a housing (4) and is embodied as a cup-shaped body with a piston bottom (6) and a sleevelike piston wall (8) protruding away from the bottom, and the face (10) of the piston bottom (6) pointing away from the piston wall (8)is pressure-loadable, and there is at least one injection point (46) oriented with a molding channel of a molding tool. The invention proposes that the injection point (46) is disposed on the other face (22) of the piston bottom (6), that is, the face pointing away from the pressure-loadable face (10), and the piston bottom (6), because of one or more recesses (48) present in this face (22), has a lesser wall thickness in the region of the injection point (46) than in the regions (52) adjoining it.

The vibration damper has a sleevelike shaped part comprising an elastomer as a diaphragm. The shaped part is received tightly on the opening end of a bore of a housing and surrounds an extension of a support body disposed in the bore. Provided on a side face of the extension is a groove, which communicates with a chamber in the extension. The shaped part, which on its outside is exposed to the brake fluid, with the inside of its jacket wall defines a hollow chamber, formed toward the extension of the support body and having atmospheric pressure. The vibration damper can be used in a slip-controlled hydraulic brake systems of motor vehicles.
