Abstract
A piston includes a piston body which is surrounded by a media side, by an oppositely disposed drive side and, at the peripheral side, by a piston jacket, wherein the piston jacket forms a connection between the media side and the drive side. The piston jacket is arranged about a piston axis, wherein the piston jacket is connected to the piston body via a web element so that a peripheral groove is formed on the media side between the piston body and the piston jacket. A cover element is arranged at the media side, and has a drive side surface which lies directly on the media side surface of the piston body.
