FIELD: engines and pumps.
SUBSTANCE: control valve for fuel injector has control bushing that restricts the increased pressure cavity and that is installed in movable manner in longitudinal direction and has a sealing surface on its edge, by means of which it interacts with its seat made on valve part and having the shape of outside flattened cone. Apex angle of the cone being the shape of the above seat is 120 to 170°. The corresponding fuel injector is described as well.
EFFECT: invention allows reducing the wear of control bushing and seat of control valve of fuel injector.
