摘要

Disclosed is a subunit consisting of a hollow cylinder ( 1 ) which is provided with an opening on at least one face and in which a spring bearing ( 2 ) is arranged on the inside of said face, a first valve spring ( 3 ) resting against said spring bearing ( 2 ). A shaft that is guided within the spring bearing ( 2 ) is disposed in the first valve spring ( 3 ) so as to be reversibly movable in the direction of the longitudinal axis of the hollow cylinder ( 1 ). A thrust bearing ( 5 ) for the first valve spring ( 3 ) is located at the end of the shaft ( 4 ), which faces away from said face of the hollow cylinder ( 1 ), said thrust bearing ( 5 ) being connected to the shaft ( 4 ). A second valve spring ( 6 ) is placed between the thrust bearing ( 5 ) and the interior on the opposite face ( 1 a) of the hollow cylinder ( 1 ).
