摘要

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