Venturi nozzle for generation of under pressure for device to separate oil from crankcase gases of internal combustion engine, has venturi tube with section narrowing to constricted opening and section widening from constricted opening

摘要

The venturi nozzle (4) has a venturi tube with a section narrowing to a constricted opening and a section widening from the constricted opening. Another venturi tube is arranged in the former venturi tube. The latter venturi tube extends along the entire axial extension of the constricted opening of the former venturi tube in an axial direction. An independent claim is also included for a device with an oil separating element for separating oil from the crankcase gases of an internal combustion engine.
