<p>Control valve (12) of a piston (2) has a control valve closing element (13) that bears a seal-forming fashion against a valve seat (21). A control valve spring (14) is embodied as a spring element that is arranged in a high-pressure space (8), spaced from an axial opening (6) and the closing element, and supported between a piston head underside (16) and a control valve holding element (15). The holding element guided in the high-pressure space holds the closing element and defines an oil passage (19).</p> |
