FIELD: engines and pumps. ^ SUBSTANCE: invention relates to engine production, particularly, to gas feed systems incorporated with gas and gas diesel engines used in movable and stationary power plants with electronic fuel feed control. The proposed electrically controlled gas valve for engine fuel feed systems comprises the body with gas inlet and outlet that houses an electrical drive furnished with electromagnet core, valve gate with two pre-tightened flat helical springs and valve seat. The latter represents several round nozzles extending beyond its surface and separated, one from the other, by gas passage space. On closing, the gate shuts off all nozzles at a time. ^ EFFECT: simplified design of valve seat, higher capacity, smaller weight and sizes, lower power consumption. ^ 8 cl, 2 dwg |
