CENTRIFUGAL SEPARATOR Russian patent published in 2014 - IPC F01M13/04 

FIELD: machine building.

SUBSTANCE: device (1) for purifying unclean gas from internal combustion engine is proposed, it comprises a centrifugal separator (2) with a centrifugal rotor (3) which is able to rotate the unclean gas. The centrifugal rotor (3) includes a set of separating disks (6) of truncated cone shape which are installed with relevant interval so that to restrict spatial gaps (7) between themselves, through which gas flows. An outlet chamber (11) is placed in the centre of the separating disk set (6) due to this fact the centrifugal rotor (3) is able of counterflow separation. The centrifugal separator comprises a gas outlet branch (13) which is connected to the outlet chamber (11) and can bleed the purified gas from the centrifugal rotor. The separating disk set (6) is installed to rotate in the space (4) formed inside the internal combustion engine and set to be able to receive the unclean gas, for this purpose the spatial gaps (7) between the separating disks (6) are communicated directly with the space (4). The gas outlet branch (13) is mounted so that to direct the purified gas from the space through a wall (5) partitioning the space.

EFFECT: improved crankcase gas purification efficiency.
