In piston/cylinder arrangements having a seal (3) liable to leakage between the working space (1b) limited by a piston (2) and a cylinder (1), on the one hand, and a leakage space (4), on the other hand, and having a leakage discharge (8) connected to the latter, there is a problem of a simple and reliable separation of the leakage medium or escaping working medium from the lubricating system or from other sensitive components of the arrangement. To solve the problem, the piston (2) is provided with a can-shaped force-transmission and guide member (5) which engages round the piston (2) and the cylinder (1) receiving the latter and which is connected by means of a gasket (6) to a surrounding housing bore (7a), the interior (4) of the force-transmission and guide member (5) being connected to the leakage discharge (8). Sufficient space is thereby provided for the expansion and spread of the leakage medium, so that the gasket (6) between the force-transmission and guide member (5) and the housing bore (7a) can work virtually free of differential pressure and therefore in an especially reliable way, whilst the interior (4) of the said member can act additionally as a pumping space for discharging the leakage medium. <IMAGE>
