Abstract

A pull cylinder actuated by pressure medium has a plunger piston (6) which can be moved by a fluid from a stroke end position in the area of a cylinder head in a direction towards the area of a cylinder base (2) through a cylinder working space (12) into an initial position, at least one air-exchange bore (3) which connects the associated piston space (11) to the ambience and has an internal filter body (18) being provided in the area of the cylinder base (2). In this arrangement, the air-exchange bore (3) is formed with an adjustable gas-exchange barrier (13). <IMAGE>
