LUBRICATION DEVICE OF INTERNAL COMBUSTION ENGINE Russian patent published in 2022 - IPC F01M1/02 F01M1/06 F01M1/16 F01M11/02 F16N27/00 

FIELD: engine building.

SUBSTANCE: invention can be used in internal combustion engines (hereinafter – ICE). Lubrication device (36) of ICE with crankshaft (10) that is connected to at least one connecting rod (12) is proposed. Device (36) includes at least one flow limiter (57), in particular a throttle valve for reducing the flow rate of lubricating fluid, directed to at least one flow limiter (57) of lubricating fluid. Device (36) contains a group of bearings (52) of the crankshaft for rotating crankshaft (10), while there is a group of bearings (52) of the crankshaft bound with fluid downstream at least first flow limiter (57). Device (36) has at least one bearing of large head (54) of the connecting rod, mounted with the possibility of rotation of at least one connecting rod (12), in which there is at least one bearing of large head (54) of the connecting rod, bound with fluid downstream at least one bearing (52) of the crankshaft of the group of bearings (52) of the crankshaft.

EFFECT: due to reduction in amount/pressure of lubricating fluid, flow rate of lubricating fluid for lubricating an internal combustion engine is reduced, thereby it is possible to use a lubricating fluid pump of a smaller size, and to reduce power of a drive for the lubricating fluid pump.
