Abstract

DC60 fuel injection valve (10) consisting of a valve body (24) directing the flow of fuel to the injection bore (23), a movable axis (34) that moves axially in the body in combination with the valve body. (24), stationary core (33) with one end of the movable core (34) facing and the section of winding (40) with the number of winding bundles of the wire harness (42). up through the movable axis in the spool (41) in order to create a magnetic attraction between the movable axis (34) and the stationary axis (33). The number of wire harnesses (42) is higher at the ends of the axis side. movable (34) in the coil (40), so the magnetic field generated will be higher on the axial In this manner, the magnetic attraction between the stationary axis (33) and the movable axis (34) is increased without increasing the cross-sectional area and/or the movable core (34). The fuel injection (10) consisting of a valve body (24) directs the flow of fuel to the injection bore (23), a movable axis (34) that moves axially in the fuselage incorporating the valve body (24). ), stationary core (33) with one end of the movable core (34) facing and the winding section (40) with a higher number of bundles of wire windings (42) towards The movable core in the Bobbin core (41) in order to create a magnetic attraction between the movable core (34) and the stationary core (33). The number of wire harnesses (42) is higher at the ends of the axis side. movable (34) in the coil (40), so the magnetic field generated will be higher on the axial In this manner, the magnetic attraction force between the stationary (33) and the movable (34) core will be increased without increasing the cross-sectional area and/or the movable core (34).
