Centrifugal oil separator for blow-by gases of an internal combustion engine
View Patent ↗In a centrifugal oil separator for blow-by gases of an internal combustion engine comprising a rotating component which has at least one inflow port for the introduction of blow-by gases from the crankcase of the internal combustion engine, at least a first outflow port for the discharge of air and at least a second outflow port for the discharge of oil, and also a driveshaft ( 12 ) driving the rotating component for driving the rotating component, the driveshaft of the rotating component is connected via a mechanical coupling to a transmission driven by a crankshaft of the internal combustion engine.
1. A centrifugal oil separator ( 10 ) for blow-by gases of an internal combustion engine, comprising a rotating component which has at least one inlet port for the introduction of blow-by gases from the crankcase of the internal combustion engine, at least a first outlet port for the discharge of air and at least a second outlet port for the discharge of oil, and also a driveshaft ( 12 ) for driving the rotating component, the driveshaft ( 12 ) of the rotating component being connected via a mechanical coupling ( 18 ) to a transmission ( 14 , 15 ) driven by a crankshaft ( 16 ) of the internal combustion engine, said mechanical coupling ( 18 ) being controllable for controlling the rotational speed of the rotating component of the centrifugal oil separator ( 10 ).
2. The centrifugal oil separator as claimed in claim 1 , wherein the transmission ( 14 ) is a gearwheel-type speed change transmission.
3. The centrifugal oil separator as claimed in claim 1 , wherein the transmission ( 15 ) is a turbo compound transmission.
