摘要
FIELD: engines and pumps.;SUBSTANCE: at gas pressure control valve displacement from one extreme position to another one the control system traces the valve current position and rate. Besides, it defines the valve deceleration start time in compliance with which the control slide valve changes the direction of gas feed from pneumatic accumulator into opposite chamber of the valve drive piston. Valve rate decreases before the motion extreme point. Then, control system returns the slide valve into previous position to make the gas set the valve to preset position. Pneumatic accumulator is charged with the energy of combustion products in ICE cylinder by compressor piston.;EFFECT: lower shock loads in the valve system.;1 dwg
