FIELD: mechanical engineering; lubricating systems of internal combustion engines. SUBSTANCE: device has supply reservoir 1, main line 2, pump 3, bypass spool 4 main and additional hydraulic accumulators 5 and 6, respectively, arranged in common housing 7 and furnished with plungers 8 and 9 made integral and coaxially with each other. Check valve 10 is installed in main line 2 at outlet of oil pump 3. Space 11 made in housing 7 of hydraulic accumulator is filled with salt melt. Space 11 encloses exhaust manifold 12 of engine. Plunger 8 of main hydraulic accumulator 5 is spring loaded. Temperature pickup 15 is installed on additional hydraulic accumulator. Burner 15 can be installed on housing 7 of hydraulic accumulators 5 and 6. Proposed invention prevents change in physical and chemical properties of oil circulating through main oil line of internal combustion engine and provides quick and reliable delivery of oil to friction surfaces. EFFECT: enlarged operating capabilities. 2 cl, 1 dwg
