摘要：The invention relates to a slot piston ring (1) for the pistons of internalcombustion engines or compressors, having a peripheral recess (9) (a so-called scraperring) that extends close to the slot (2) on the external periphery (3) of the piston facingaway from the combustion chamber. The aim of the invention is to reduce oil
consumption and the amount of leakage gas of such a piston. To this end, the recess isconfigured to extend from a zone (10) diametrically opposite the slot, starting with amaximum height (12) which gradually decreases to zero (13) in the direction of the slot orclose to the slot.
