Said device comprises a piston which is is mounted in a cylinder, can be displaced back and forth, and is driven by an especially electromechanical drive which is preferably connected to a battery. Said piston comprises an annular seal on the inner wall of the cylinder. According to the invention, the annular seal (17) has a number of cuts (45), preferably between 6 and 12, especially between 8 and 10, especially for improving the sealing and compression behaviour.
