FIELD: engines and pumps.
SUBSTANCE: invention can be used in the internal combustion engines. Engine comprises the first controlled valve configured to open / close the engine combustion chamber, and the gas distribution system configured to control the first controlled engine valve. Gas distribution system comprises closed pneumatic circuit for the pressurized fluid medium. Pressurized fluid medium closed circuit comprises in-series connected to each other compressor (31) and valve actuator (10), operatively connected to the first controlled engine valve. Gas distribution system additionally comprises the gas accumulator (38), connected to the pressurized fluid medium closed circuit by means of containing the controlled valve (40) at least one gas accumulator conduit (39). Disclosed is the gas distribution system for the valve actuator (10) pneumatic control.
EFFECT: technical result consists in provision of possibility to increase the pressure difference between the low-pressure side and the high-pressure side by increase in the pressure on the pressurized fluid medium circuit high-pressure side.
