Piston-rod-less pneumatic cylinder, has end position damping arrangement with stroke space that is delimited by movable stroke element, where space is connected via connecting duct by working pressure or by ventilation pressure

摘要

The cylinder (1) has an end position damping arrangement with a stroke space (9) that is delimited by a movable stroke element (7). The space is connected via a connecting duct (14) by working pressure (P1) or by ventilation pressure. The element is pressurized by a damping pressure (P2) via a damping duct (16) that includes a non-return valve (12) in the connecting duct upstream of the space. The valve blocks in direction of the working or ventilation pressure and includes a ventilation duct (5). The ventilation duct is opened by the element and is connected to the outlet duct. An independent claim is also included for a method for self-adjusting end position damping of a cylinder position.
