Abstract
A pneumatic cylinder with damping in the end position, also comprising a housing in which at least one slide rod element is mounted with at least one sealing element, in such a way that said slide rod element is linearly displaceable. At least one damper sleeve or its bearing arrangement is associated with the slide rod element, said bearing arrangement engaging with front-end bearing elements in the end positions. According to the invention, the damper sleeve or its bearing arrangement has at least one indentation for damping the end position and for ventilation.
Claims28
Pneumatic cylinder with end position damping, having a housing (1) in which at least one push-rod element (3) with at least one sealing element (6) is mounted to be movable in a linear manner, at least one damper sleeve (5) being assigned to the push-rod element (3) and engaging, in the end positions, into end face bearing elements (2.1, 2.2), characterized in that, for end position damping and ventilation, the damper sleeve (5) or the bearing (13) thereof comprises at least one notch (8).
Pneumatic cylinder with end position damping, having a housing (1) in which at least one push-rod element (3) with at least one sealing element (6) is mounted to be movable in a linear manner, at least one damper sleeve (5, 5.1) being assigned to the push-rod element (3) and engaging, in the end positions, into end face bearing elements (2.1, 2.2), characterized in that, for end position damping and ventilation, the damper sleeve (5.1) and/or the bearing (13) thereof comprises at least one recess (14) and/or bore (15).
Pneumatic cylinder with end position damping, having a housing (1) in which at least one push-rod element (3) with at least one sealing element (6) is mounted to be movable in a linear manner, at least one damper sleeve (5) being assigned to the push-rod element (3) and engaging, in the end positions, into end face bearing elements (2.1, 2.2), characterized in that at least one overpressure valve (20) is assigned to the bearing element (2.1, 2.2).
Damper sleeve or bearing thereof, especially for push-rod elements (3) for pneumatic cylinders, characterized in that for end position damping and ventilation the damper sleeve comprises at least one notch (8) and/or recess (14) and/or bore (15).
