It states fuel feed hole to connect with oil inlet pipe, Fuel Cut Solenoid Valve, Fuel Cut Solenoid Valve is equipped with positioned at the top of pilot hole in the oil inlet screw
Armature be set in the pilot hole move back and forth between the fuel feed hole and oil outlet by oil inlet screw connect or close.
The fuel feed hole of the oil inlet screw is arranged on the side side wall of oil inlet screw, and oil outlet is set under fuel feed hole
Side and with the central axes coaxial arrangement of oil inlet screw, the pilot hole, the hole of pilot hole are set between fuel feed hole and oil outlet
Diameter is more than fuel feed hole aperture and oil outlet aperture.
It is set to outside the armature between the fuel feed hole and oil outlet of oil inlet screw and is enclosed with sealing element.
The sealing element is rubber sleeve.
It is threadedly coupled between the oil inlet screw and the pump housing oil inlet of oil pump assy.
A kind of flameout method based on the automatically controlled VE types dispensing pump, when oil pump powers off, the oil inlet electricity on oil pump pump head
Fuel Cut Solenoid Valve simultaneously closes off on magnet valve and oil inlet screw, even if entering there are diesel oil from plunger drain tap and spraying into engine
In, since the pump housing oil inlet of oil pump assy is closed by Fuel Cut Solenoid Valve, pump chamber pressure reduces rapidly, and makes the oil-filled reduction of plunger,
So as to be reduced to the fuel feeding of engine, engine stops working rapidly.
Advantageous effect：
A kind of automatically controlled VE types dispensing pump of the present invention is set by increasing Fuel Cut Solenoid Valve in automatically controlled VE types dispensing pump oil inlet screw
Meter cuts off oil pump oil inlet during power-off, and pump chamber pressure reduces rapidly, and makes plunger is oil-filled to reduce from the fuel feeding reduction to engine, together
When can also reduce fuel injection timing, engine is promoted to stop working rapidly and ensures that the power-off of engine is stopped working.
In addition, the oil inlet screw of script is increased Fuel Cut Solenoid Valve design by the present invention, have and facilitate installation, at low cost have
Beneficial effect.
