Abstract

A pneumatic cylinder assembly (1) comprises an outer cylinder element (2), an inner cylinder element (3), which is telescopically displaceable in the axial direction (a) relative to the outer cylinder element, and a piston element (4), which is telescopically displaceable in the axial direction (a) relative to the inner cylinder element (3). The elements (2-4) together define a pressure chamber (6', 11') for extension of the inner cylinder element (3) from the outer cylinder element (2) and of the piston element (4) from the inner cylinder element (3), and pressure chambers (6'', 11'') for retraction of the inner cylinder element (3) into the outer cylinder element (2) and of the piston element (4) into the inner cylinder element (3). At least one non-centrally arranged telescopic tube (23, 24) extends in the axial direction (a) through the cylinder elements (2, 3) and the piston element (4). The tube (23, 24) is adapted to lock the piston element (4) against rotation relative the outer cylinder element (2) and to establish a tight connection between a pressure medium connection (27, 28) at the rear end wall (5) of the outer cylinder element (2) and a pressure medium connection intended for a pneumatic or hydraulic tool, such as a gripping jaw, connected to the piston element (4).
