Ventilation valve arrangement for internal combustion engine for mounting between crankcase chamber and suction tract of internal combustion engine, has membrane which releases flow channel for aerating crankcase chamber in valve position

摘要

The ventilation valve arrangement (1) has a membrane (7) which releases a flow channel (11) for aerating a crankcase chamber in a valve position (A) and closes another flow channel (12) for ventilating the crankcase chamber. The ventilation valve arrangement deaerates the crankcase chamber in the valve position and ventilates the crankcase chamber in another valve position. An independent claim is also included for a method for manufacturing a ventilation valve arrangement.
