摘要

The piston (7) and cylinder (3) unit whose stroke can be adjusted has a stop, formed by the piston itself, and a counter stop (27) mounted on the cylinder. The axial position of one or both of these can be adjusted and they have cooperating surfaces (31, 33) which can be brought into contact to adjust the stroke.
