摘要： The invention relates to a pneumatic drive, comprising a pneumatic drive unit (1), which has a piston (3) that can be moved between a first position and a second position. The piston is accelerated and braked by means of compressed air, which is fed to or led away from the pneumatic drive unit by means of valve arrangements (8, 9) having distribution valves (16, 17, 21, 22). In at least one distribution valve (17, 22), a damping throttle (20, 25) is provided, which has a differential pressure piston (28), which can be moved as a function of the compression pressure, whereby the free throttle cross-section (49) through which the compressed air flows can be changed as a function of the compression pressure.

摘要： A hydraulic cylinder with end position damping includes at least one cylinder in which there is arranged at least one piston which is connected to at least one piston rod and can be moved in the axial direction, wherein the cylinder is subdivided by the piston into a piston side and a rod side and the hydraulic oil necessary for actuating the piston is pumped by a hydraulic pump via inlet and outlet lines through inlet and outlet openings provided on the cylinder, wherein the cylinder is assigned a mechanical prethottling via which, during the movement of the piston, the hydraulic oil can be discharged on the rod side through a first bore until the piston, during its movement, closes the first bore and the hydraulic oil is thus discharged through a second bore, wherein, at a preset pressure, the mechanical prethrottling means forces the hydraulic pump into an electronically regulated pressure cutoff function which reduces the delivery rate of the hydraulic oil and the piston can be moved into its end position in a braked manner.

摘要： A device for affixing an adhesive label to a package comprises a piston and cylinder. The cylinder comprises two connections arranged on a wall of the cylinder spaced apart from each other, which are alternatively connected to either a positive or a negative pressure media source. The connections control the movement of the piston inside the cylinder so that the piston can move between a first dead center position and a second dead center position thereby causing a stamp to affix a label to the package. Shortly before reaching the first dead center, the piston blocks the first connection with its cylindrical wall, thereby stopping any increase in negative pressure between the piston and the first dead end position.
