Centrifugal oil separator for blow-by gas of combustion engine

摘要

Centrifugal oil separator (10) comprises a rotating component having a drive shaft (12) which is connected via a mechanical coupling to a transmission (14) driven by a crankshaft (16) of an I.C. engine. Preferred Features: The transmission is a toothed wheel change gear. A coupling (18) for controlling the revolutions of the rotating component of the centrifugal oil separator is arranged between the drive shaft and the transmission. The drive shaft is connected to a hydraulic drive which is integrated in a fuel line of the engine. The hydraulic drive is integrated in a low pressure fuel cycle between a fuel conveying pump and a fuel high pressure pump.
