Abstract

Crank housing ventilation valve with an integrated cyclone separator (2) comprises a valve chamber (30) defined on one side by a membrane (54) and on the opposite-lying side by a separating wall (32) separating the valve chamber from the cyclone separator. The cyclone separator has a gas inlet (6) connected to the crank housing, a gas outlet (42) connected via a guide channel (40) to the valve chamber and near the gas outlet an oil outlet (8) connected to an oil return. An intake channel connected at one end to a vacuum source passes through the cyclone separator and protrudes with its other end forming a valve seat (24) into the valve chamber. The valve seat interacts with the membrane, which is spring-loaded in the opening direction.
