The cylinder has two respective driving fluid ports in the two gables of the cylindrical tube. These are for operating the cylinder in opposite directions. Cylindrical piston connecting rods (6-9) move in and out of each other and in the outer tube. Each of the connecting rods in the drawn-in position is peripherally sealed with one end against the closed gable (2), and have first and second stops (28-32) at their ends to limit the outward movement of the rod. - The connecting rod has at least one fluid aperture (38-41) at their second end and inside the second stop. Such apertures are sealed against pressure fluid when its movement is limited by the stop.(1) |
