Abstract (en)

The piston (20) has a piston jacket (21) having a longitudinal piston axis (28) and a media side surface (26), and a venting device (22) for venting air from the media side surface side. The venting device includes a cut-out (23) in the piston jacket and a radial passage (29) in the media side surface extending in a radial direction from the cut-out in the piston jacket towards the piston axis. The radial passages are arranged at the same spacing from one another, where the radial passage is designed as a slit with an open cross-section.
