OIL FEED DEVICE FOR ICE, PARTICULARLY, FOR ICE CRANKCASE Russian patent published in 2016 - IPC F01M11/04 F01M11/03 

FIELD: engines and pumps.

SUBSTANCE: invention relates to ICE lubing. Claimed device comprises at least one oil tank and at least one oil feeder. The latter forces oil from oil tank via at least one flow channel into at least one main lubing channel of the ICE crankcase. Note here that several oil filter units are arranged on the way of oil from oil tank to at least one lubing channels. Note also that the filter changeover device meant for selective oil filter unit engagement with oil flow along the main lubing channel makes at least one active unit of oil filter is flown by oil. Note that the other portion of oil filter, as a passive unit, is not flown by oil. In compliance with this invention, the changeover unit (7) is arranged on the way of oil flow from oil tank (3) to oil filter units (11, 17). Said changeover device (14) makes, at certain position of its engagement, the portion of oil filters active while the other portion (11, 17) is engaged passively. Besides, it clears the first oil flow path from oil tank (3) to at least one active unit (11, 17) of oil filter. Also, it creates the second oil flow path for draining between at least one passive unit (11, 17) and drain channel (20). Note here that drain channel (20) is communicated with the drain device, in particular, a suction device (21) for oil collected in the area of at least one passive unit (11, 17) to be drained, in particularly, sucked off.

EFFECT: oil filter replacement during engine operation.
