    Abstract A rotor-type apparatus (10) for centrifugal cleaning of crank case gases from acombustion engine. The rotor (16) is hydraulically driven by pressurized oilthrough a turbine wheel (32) located in an oil collection chamber (30). Apressure equalizing and gas discharging conduit (46), which extends into thecollection chamber (30) and has an upper aperture (48) located above a liquidlevel (h) of the oil in the collection chamber (30) during the operation, isconnected to an outlet conduit (44) for the propellant oil from the collectionchamber (30).

    Apparatus for cleaning crank case gases Technical field The present invention relates to an apparatus for cleaning crank case gasesfrom a combustion engine, wherein the apparatus comprises an hydraulicallydriven centrifugal separator, which includes: - a rotor that is rotatably supported in a stationary casing and has a plurality oflamella discs stacked upon one another about the center axis of the rotor forcleaning the crank case gases from oil particles and solid particles; - an inlet in the separator for uncleaned crank case gases; - an outlet in the separator for cleaned crank case gases; - an outlet in the casing for the discharge of particles separated out from crankcase gases; - a turbine wheel connected to the rotor shaft for the rotation of the rotor; - a supply line for feeding pressurized propellant oil to the turbine wheel: - a chamber in the casing for the collection of propellant oil having passedthrough the turbine wheel; - a propellant oil outlet in the bottom of the chamber; and - an outlet conduit for the discharge of the propellant oil from the propellant oil outlet.
    Background of the technology ln gas cleaning devices of the above-mentioned type gas in the collectionchamber is mixed with the propellant oil from the turbine wheel, so that, whenthe propellant oil flows down in the outlet conduit, gas bubbles are generatedtherein which form a larger gas accumulation in the outlet conduit. The moregas being collected in this gas accumulation, the higher the pressure will betherein. The high pressure in the gas accumulation in combination with the lowpressure of the propellant oil prevailing in the collection chamber makes itdifficult for the oil in the bottom of the collection chamber to flow out through the oil outlet and down through the outlet conduit back to the oil pan of the engine, since the weight of the oil column in the outlet conduit is insufficient forcompensating for the pressure acting upwards from the gas accumulation. Asa result, the collection chamber is filled up with oil which eventually slowsdown the turbine wheel therein and thus deteriorates the function of the cleaning apparatus.
    Summary of the invention ln order to solve this problem it is suggested in accordance with the presentinvention that a pressure equalizing and gas discharging conduit is providedbetween the outlet conduit and the collection chamber, so that an upperaperture of the gas discharging conduit is located above a liquid levelgenerated during the operation by the oil in the collection chamber. Hereby asubstantially equal high pressure is obtained in the gas accumulation in theoutlet conduit as in the collection chamber, which allows for the propellant oil to flow down without problem through the outlet conduit by gravity.
    The invention is described more in detail below with reference to the accompanying drawing.
    Brief description of the drawing figureThe figure illustrates schematically an embodiment of an apparatus according to the invention.
    Detailed description of a preferred embodiment of the invention ln the drawing figure 10 generally denotes a rotor-type separation apparatusfor centrifugal cleaning of crank case gases from a combustion engine. Theapparatus 10 comprises a stationary casing 12 which delimits a separationchamber 14 in which a rotor 16 known per se is rotatable, wherein the rotor 16supports a plurality of separation discs 18, such as closely separated conicallamellae, stacked upon one another. The casing 12 has an inlet 20 foruncleaned crank case gas from a crank case 22 of a combustion engine, anoutlet 24 for crank case gas cleaned from oil particles and solid particles, and a schematically shown outlet 26 for separated-out particles. ln the gas outlet 24 there is a pressure control member 28 which is configured to maintain adesired sub pressure in the separator. Beneath the separation chamber 14there is a chamber 30 which encloses a turbine wheel 32 connected to driveshaft 34 of the rotor 16. Via a supply conduit 35 the turbine wheel 32 is drivenby pressurized oil from an oil pump 36 that pumps oil from the oil pan 40 of theengine. The turbine wheel 32 has substantially tangentially directed outletnozzles (not shown). Optionally, one or more stationary nozzles are used for propelling a Pelton-type turbine.
    The chamber 30 is an accumulation chamber for the propellant oil for theturbine wheel and has an oil outlet 42 at the bottom of the chamber 30. The oiloutlet 42 is connected to a return conduit 44 for the feedback of the propellantoil to the oil pan of the engine. ln accordance with the present invention apressure equalizing and gas discharging piping 46 extends from the returnconduit 44 up to the collection chamber 30 and has an aperture 48 thereinabove the oil level h in the chamber 30 during the operation. Owing to thispressure equalizing piping 46, the drainage and the feedback of the propellantoil from the collection chamber 30 to the oil pan 40 of the engine is facilitated essenüaHy.
