FIELD: engine building.
SUBSTANCE: invention can be used in the internal combustion engines. Method of driving gas-distributing valve of internal combustion engine is intended for gas-distributing valve (10) with liquid reciprocating electric drive, which includes coil (1) of reciprocating electric drive, plunger-magnet (2), check valves (3), (4), (6), (8), (9), (20) of plunger-magnet cavity, power hydraulic accumulator (5), compensating hydraulic accumulator (7), control system, gates of double-seat valve (11), channels (13), (14), (18) of double-seat valve gate and cavity (15), (16) of piston of gas-distributing valve drive (10). Method consists in the fact that at supply of sign-changing voltage to coil (1) of liquid reciprocating electric drive plunger-magnet (2) performs oscillatory movements, at which liquid from both cavities of plunger-magnet (2) through one pair (3), (4) of check valves enters power hydraulic accumulator (5), and through another pair of check valves (6), (9) liquid from compensation hydraulic accumulator (7) is supplied to opposite cavities of plunger-magnet (2). Control system establishes gates of double-seat valve (11) into position, at which fluid from power hydraulic accumulator (5) through double-seat valve shutter channel enters that cavity (15) of piston of gas-distributing valve (10), when gas distributing valve (10) is opened, liquid from opposite cavity (16) of piston of gas-distributing valve drive is fed via valve channel (18) of double-seat valve into compensation hydraulic accumulator (7). In order to close gas-distributing valve (10) control system installs gates of double-seat valve (11) into position, at which fluid from power hydraulic accumulator (5) through channel (18) of gate of double-seat valve (11) enters that cavity (16) of piston of drive of gas-distributing valve, at supply to which gas-distributing valve (10) is closed. Fluid from opposite cavity (15) of piston of drive of gas-distributing valve (10) via channel (13) of gate of double-seat valve (11) is supplied to compensation hydraulic accumulator (7).
EFFECT: technical result consists in improvement of service life of gas distributing valve drive system.
