Fig. 1 is form structure front view of the present utility model;
Fig. 2 is that the A of Fig. 1 is to the K-K cross section view;
Fig. 3 is the utility model and solenoid valve D supporting structure generalized section;
Among the figure, 1-coil carrier, 2-coil, 3-armature, 4-iron core, 5-valve body, 6-spool; A-line of vision symbol, T-copper wire, E-guide pillar, F-coil envelope is moulded H-sheath, K-cross section symbol, N-conductive pole, P-conducting plate, D-solenoid valve.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is illustrated.
Consult Fig. 1, Fig. 2, winding around 2 on the coil carrier 1, coil 2 adopts the copper wire T of diameter phi 0.48～0.55mm, twine 55～90 circles, the two ends of copper wire T pass from the conductive pole N center hole of coil carrier 1 respectively, in order to connect solenoid valve D, conductive pole N and guide pillar E outside suit sheath H, coil 2 outsides that wind are moulded F with the coil envelope and are encapsulated on the coil carrier 1.
Consult Fig. 3, spool 6, iron core 4, coil block are arranged in the valve body 5 of solenoid valve D, coil block is installed on the interior iron core 4 of solenoid valve D, suit armature 3 in the center hole of iron core 4, spool 6 tops contact armature 3, coil 2 passes the conducting plate P of the copper wire T end connection solenoid valve D of conductive pole N, connects ECU (Electrical Control Unit) (ECU) by circuit again.Solenoid valve D integral installation is located on the electrical control oil spray pump, is controlled by ECU (Electrical Control Unit) (ECU).When ECU (Electrical Control Unit) is sent control signal to solenoid valve D, coil 2 energisings make iron core 4 produce electromagnetic forces, attract armature 3, and armature 3 makes its closure to spool 6 application of forces, and the fuel flow path of Injection Pump is closed, and forms hyperbaric chamber.Along with the action of Injection Pump end cam and plunger, after the fuel oil in the hyperbaric chamber is compressed, to oil sprayer, realize the purpose of electronic fuel injection through the outlet valve spray feed.Because the copper wire T of coil 2 adopts 0.48～0.55mm thick line, coil 2 twines the number of turn selects 55～90 circles, reduced the number of turn, static resistance only is 0.25～0.5 ohm, and inductance is 1.2～1.8 milihenries, makes the driving voltage of electromagnetic valve coil be reduced to 55V, power loss reduces, for the research and development of the circuit design of ECU (Electrical Control Unit) (ECU) provide favourable basis, created good condition, promoted development and the raising of electronic control injection systematic function.
