Bypass device for crank case venting system of internal combustion engine for motor car, has oil separation device whose coalescence element is provided between gas inlet and valve inlet of bypass valve in flow-technical manner

摘要

The device (10) has a housing (12) formed with a bypass channel, which comprises a gas inlet (24) and a gas outlet (26) for crank case ventilation gas. A bypass valve (32) disconnects the gas inlet from the gas outlet. An oil separation device (58) separates oil from the ventilation gas. The oil separation device comprises a coalescence element (62) e.g. hollow cylinder, which is provided between the gas inlet and a valve inlet (64) of the bypass valve in a flow-technical manner. The coalescence element comprises a non-woven fabric, a mesh fabric, a granule and/or a wire arrangement.
