FIELD: engines and pumps.
SUBSTANCE: invention relates to engine building industry, particularly to fuel equipment of internal combustion engines. According to the proposed version, an injector includes a housing with the first tail-piece opposite to the second tail-piece. The second tail-piece is designed with possibility of location near the combustion chamber, and the first one - with possibility of location at a distance from the combustion chamber. The injector also includes an igniting conductor, passing through the housing from the first tail-part to the second tail-part, and an isolation passing along the igniting conductor and embracing at least a part of igniting conductor. The injector also includes a valve passing along the isolation from the first tail-part to the second tail-part. The valve includes a sealing tail-part, and the valve is designed with possibility of movement along the isolation between open and closed position. The injector also involves a valve seat in the second tail-part of the housing or near the second tail-part of the housing. When the valve is in open position, the sealing tail-part is at a distance of the valve seat, and when the valve is in closed position, the sealing tail-part contacts with at least a part of the valve seat.
EFFECT: proposed are the versions for implementation of injectors for injection passages with relatively small diameters.
