| 摘要 |
The invention relates to a piston (1, 51) comprising a piston body (2, 52), which is surrounded by a media side (3, 53), an opposing drive side (4, 54) and circumferentially by a piston skirt (5, 55), wherein the piston skirt (5, 55) forms a connection between the media side (3, 53) and the drive side (4, 54). The piston skirt (5, 55) is arranged about a piston axis (9), wherein the piston skirt (5, 55) is connected by means of a web element (26, 76) to the piston body (2, 52) such that a peripheral groove (23, 73) is formed between the piston body (2, 52) and the piston skirt (5, 55) on the media side (3, 53). On the media side (3, 53), a cover element (13, 63) is arranged, which has a drive-side surface (29, 79) that is directly seated on the media-side surface (28, 78) of the piston body (2, 52). |
