Abstract

The invention relates to machine-building, in particular to gas-distributing mechanism of combustion engine. Hydraulic drive of valves of gas-distributing mechanism of combustion engine proposed has two pistons placed in recess of head. The upper piston is in contact with cam of distribution shaft, and the lower one – with valve of gas-distributing mechanism. To inter-piston cavity, through check valve, lubricant comes from pressure cavity of oil pump of lubrication system of engine. To inter-cavity hydro-accumulator and dozer are connected. The dozer changes amount of working liquid that comes from the upper to the lower piston with change of stroke of valves of gas-distributing mechanism, and hydro-accumulator provides quick start of the engine after stoppage. Due to that only one spool valve installed in dozer is used for control of stroke of valves high accuracy at control of valve stroke is achieved.
