SELF-CONTAINED OIL SUPPLY SYSTEM TO INTERNAL COMBUSTION ENGINE AND TURBO COMPRESSOR Russian patent published in 2019 - IPC F01M1/02 F01M11/04 

FIELD: engines and pumps.

SUBSTANCE: invention relates to a lubricant of internal combustion engines and components thereof with engine oil under pressure prior to start-up, as well as for turbo-compressor shaft cooling after internal combustion engine operation. Autonomous oil supply system to internal combustion engine and turbo compressor comprising oil pump with electric drive, controlled by control unit connected to ignition lock and having electrical connection to storage battery, oil temperature sensor, according to invention, the system has autonomous oil pump, additional oil temperature and pressure sensor mounted on oil-pumping pipeline of autonomous oil pump, wherein main oil line of internal combustion engine and standard line of oil supply to turbo compressor are connected to line of autonomous oil supply through check valve, and flows of the pressurized oil are controlled by electric valves, which are mounted on the oil supply line to the main oil line and on the oil supply line to the turbocompressor shaft, control of electric valves and duration of operation of autonomous oil pump is performed by control unit.

EFFECT: invention provides oil supply to friction elements of the engine before start-up, as well as turbo-compressor shaft cooling after engine shutdown.
