INTERNAL COMBUSTION ENGINE PRESTARTING LUBRICATING DEVICE Russian patent published in 1999 - IPC

FIELD: mechanical engineering; lubricating systems of internal combustion engine. SUBSTANCE: device has oil pump, electromagnetic valve, starter solenoid pickup, hydraulic accumulator with first and second spaces divided by spring-loaded piston with seals. Main oil line is connected with second space of hydraulic accumulator through starter solenoid switch pickup. Spring-loaded valve is installed in piston of hydraulic accumulator. Rod this valve selected to provide opening of valve in extreme position of piston when it rests on bottom of hydraulic accumulator allowing oil from second space pass into crankcase. Dielectric cup installed in second space of hydraulic accumulator accommodates oil heating coil electrically coupled through switch with storage batteries. EFFECT: facilitated starting of engine, increased service life of crank-and-connecting rod mechanism of internal combustion engine. 1 dwg
