FIELD: engines and pumps.
SUBSTANCE: invention describes the ICE fuel nozzle, mainly common-rail system atomiser with control valve (19). The latter makes a hydraulic communication of control chamber (13) coupled with injection control valve (9) to low-pressure zone (8). Said valve incorporates valve element (18) driven axially by appropriate actuator. The latter as-closed interacts by its sealed part (31) with seat (20) and is axially driven by guide (24). In compliance with clamed invention, centre (M) of imaginary circle (26) is located within the limits of axial length of guide (24). Said circle in the plane of lengthwise cross-section of fuel nozzle (1), wherein located is the lengthwise axe (L) of valve (18), contacts with the seta (20) of valve (18) or interacting with seat (20) of sealing part (31) at two spaced apart points (P1, P2). Circle centre (M) is spaced from axial centre (25) of guide (24) by distance making less that 40% of its axial length.
EFFECT: sealed fit of the vale in its seat.
