Abstract (en)

An elastomeric or mechanical damping mechanism (4) and a gas hydraulic damping mechanism (5) support a tappet (2) in a case (1). The damping mechanism (5) includes a cylindrical pressure chamber (9) that becomes smaller when a piston (7) is driven into the pressure chamber. An outlet (15) formed between the cylinder wall (6a) of the pressure chamber and the piston leads to a receiving chamber (10) through a duct (14). The portion of the piston introduced into the pressure chamber is cylindrical and exhibits a constant outside diameter.
