Abstract
An actuator for a valve in an internal combustion engine includes a housing, an electric drive unit arranged in an interior of the housing, an aeration opening arranged in the housing, a plug configured to electrically connect the electric drive unit to a voltage source, and a membrane comprising pores. The membrane is configured to close the aeration opening in the housing.
Claims19
An actuator for a valve in an internal combustion engine, the actuator comprising:
- an electric drive unit;
- a housing configured to separate an interior in which the electric drive unit is arranged from an exterior;
- an aeration opening arranged in the housing, the aeration opening connecting the interior and the exterior;
- a plug configured to electrically connect the electric drive unit to a voltage source;
- and
- a membrane comprising pores, the membrane being configured to close the aeration opening in the housing so that a gas can flow either from the exterior into the interior or from the interior to the exterior.
