ABSTRACT:
The invention relates to a slot piston ring (1) for the pistons of internal combustion engines or compressors, having a peripheral recess (9) (a so-called scraper ring) that extends close to the slot (2) on the external periphery (3) of the piston facing away 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 is configured to extend from a zone (10) diametrically opposite the slot, starting with a maximum height (12) which gradually decreases to zero (13) in the direction of the slot or close to the slot.
