Abstract

A sealing system for an internal-combustion engine is provided in which a lubricating-oil-carrying space particularly an oil catching space, is separated by wall elements from adjoining space sections, which wall elements have elastic sealing elements for sealing off the spaces. For the compensation of sealing gap tolerances, a sealing element is provided which has at least two sealing arms which come to rest on the space wall to be sealed off. Despite larger sealing gap tolerances, a secure oil-tight separation of spaces is thereby provided.
