DEVICE FOR LUBRICATING CONROD BEARING AND VEHICLE Russian patent published in 2022 - IPC F02F3/22 F01M1/06 F01M1/08 F16C33/10 F16C7/02 

FIELD: engine building.

SUBSTANCE: invention can be used in internal combustion engines. A device for lubricating conrod bearing (46) on crankshaft (24) of an internal combustion engine is proposed. The device includes piston (10) with working fluid channel (12) and outlet channel (26) connected to channel (12) via fluid. The device includes connecting rod (22) with small hole (38) and large hole (44), and connecting channel (48). Small hole (38) in a head of the connecting rod is connected to outlet channel (26) via fluid. Connecting channel (48) forms a connection via fluid between small hole (38) in the head of the connecting rod and large hole (44) in the head of the connecting rod, due to which working fluid, in particular lubricating and cooling fluid, is supplied from working fluid channel (12) through outlet channel (26), small hole (38) in the head of the connecting rod, and connecting channel (48) to large hole (44) in the head of the connecting rod.

EFFECT: conrod bearing (46) can be lubricated with cooling oil from working fluid channel (12) in piston (10), which allows for refusal from labor-intensive and durability-decreasing holes in crankshaft (24), designed for supply of oil to conrod bearing (46).
