TURBOCHARGER Russian patent published in 2021 - IPC F02C3/00 

FIELD: turbocharger design.

SUBSTANCE: invention relates to the design of a turbocharger, i.e. an energy machine that allows using your kinetic energy to pump air, a fuel-air mixture for the purpose of its subsequent use in the desired device. The effect is achieved by the fact that the turbocharger contains a middle, turbine and compressor casing, characterized in that the middle casing includes an oil supply channel that passes into the oil supply cavity, has an axial hole in which a pair of bearings is located on opposite sides with a gap, a bushing is installed between the bearings, having at least a pair of oil drainage holes, passing at an angle to its axis and passing into the oil injection channel, while a shaft passes through the axial hole of the bushing, which in the area of the bushing at the points of oil inlet and outlet has a pair of blocks of spiral screw channels twisted to the side oil drain holes.

EFFECT: equipping the compressor with a passive oil supply system, i.e. obtaining a passive oil pump that does not require the use of an additional pump, or significantly reduce the power when using it.
