Background technique
At present, China's major part non-rice habitats diesel-engine road vehicle adopts the motor that mechanical type fuel oil injectionpump is housed, and diesel engine adopts compressing ignition mode to carry out work, therefore during diesel motor flameout, not only needs powered-down, also must cut off diesel oil supply;
Conventional diesel engine usually needs to take the mode pulling fuel cut-off handle to carry out oil-break and stops working, before fuel cut-off handle be the mode manually handled to cut off fuel feeding, operate very inconvenient, and with the direct power-off of petrol engine flame-out manipulate be accustomed to different;
For this reason, develop fuel shut-off solenoid and directly manipulate fuel cut-off handle to make the automatic control mode of engine misses; Fuel shut-off solenoid is arranged on mechanical type Injection Pump, by the power supply of diesel-oil vehicle storage battery, it is powered, and by fuel shut-off solenoid self break-make with its coil of control circui, and then control the action of fuel cut-off handle, and then cut off or open fuel path, flame-out and the full-load operation of final control diesel engine, as Chinese patent 02223381.4 disclosed " fuel shut-off solenoid ", Chinese patent 200420066697.4 disclosed " external driving type passive action oil stop electromagnet " etc.;
But; find in actual use; the fuel shut-off solenoid of these routines often can produce wearing and tearing because armature is mated the continuous to-and-fro motion of cover; and then occur that fuel shut-off solenoid action is inaccurate, insensitive, the bad phenomenon such as clamping stagnation, heating are even stuck, finally cause diesel engine to occur normally stop working or the fault of normal startup.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of fuel shut-off solenoid effectively reducing the high abrasion of friction factor.
The purpose of this utility model is achieved in that
