Description
Technical field
The present invention relates to a kind of vaporizer, be meant a kind of electric-controlled injection carburettor especially with solenoid valve electric-controlled injection device control oil inlet quantity.
Background technique
At present, the vaporizer kind of report and appearance is a lot of on the magazine and market, its structure is different, but the effect and the principle of all vaporizers are basic identical, it all is the mixed airflow that control enters the empty G﹠O of engine, wherein air stream is that when you touched the throttle trigger of motor, you were exactly the amount that enters the air of engine in control by the determining positions of throttle.Oil stream is controlled by spindle.These spindles in fact are a kind of screws, and they have tapered end, stretch into oil circuit from the seat of hole, and oil flows through the chamber at spindle place, if spindle turns clockwise, it has just reduced circulation area, reduce the flow of oil thus.Opposite, if spindle is rotated counterclockwise, circulation area increases, and therefore has more oil to flow through.Also there are some vaporizers that a plurality of spindles are arranged in addition, except that main spindle, also have low speed needle and middle and high fast spindle.Existing vaporizer, it includes carburetor body and is arranged on carburetor body interior throttle adjustment screw, throttle plate pin, adjusting spindle, accumulator and trunnion, seal between its accumulator and the trunnion, so having only by regulating spindle, the size of fuel feeding regulates, the vaporizer that this utilization adjusting spindle is controlled oily flow exists some defectives: 1, fuel delivery is accurate inadequately, thereby cause the mixed gas ratio that can not provide ideal, make vaporizer can not take into account peak output and maximum speed simultaneously; 2, the mixed gas of Shi Xiaoing is known from experience to motor and is brought maximum discharge and high oil consumption, influences environment, destroys the ecological balance; 3, the mixed gas that lost efficacy is known from experience the startability that influences motor.
Summary of the invention
The novel electric-controlled injection carburettor of advantages such as the present invention has overcome the deficiencies in the prior art, provides a kind of rational in infrastructure, can accurately provide fuel delivery, and ideal mixed gas is provided, and makes engine startability good, and pollution emission is little.
Realize above-mentioned purpose, the present invention adopts following technological scheme: the vaporizer of～kind of charged magnet valve electric-controlled injection device, include carburetor body and be arranged on throttle adjust screw on the carburetor body, throttle plate pin spare, lubricating cup, accumulator, trunnion, oil inlet pipe and oil outlet tube, it is characterized in that: the passage of described oil inlet pipe and trunnion is provided with solenoid valve electric-controlled injection device, this solenoid valve electric-controlled injection device includes the oil nozzle that communicates with trunnion, one end cooperates the push rod of controlling oil pump capacity with oil nozzle, the other end of push rod is provided with the flexible magnetic induction mechanism of control push rod.
The further setting of the present invention is: the oil nozzle of described solenoid valve electric-controlled injection device is provided with a cavity near push rod one side, and this cavity communicates with oil inlet pipe on the carburetor body.
Of the present invention further the setting again is: the jet of the oil nozzle on the described solenoid valve electric-controlled injection device directly is right against trunnion, the opposite side that is positioned at jet of described oil nozzle is provided with the taper mouth that communicates with jet, described push rod be arranged to the taper platform corresponding with the oil nozzle abutting end with taper mouth.
Beneficial effect: be provided with solenoid valve electric-controlled injection device by the passage that adopts oil inlet pipe and trunnion, thereby utilize the solenoid valve electric-controlled injection to control the delivery volume of oil, can reach high-precision delivery volume like this, thereby under different fuel feeding situations, can provide the ratio of mixed gas stably to motor, make engine startability good, the pollution of exhaust emissions reduces, and prolongs its working life.Again owing to adopt the oil nozzle of solenoid valve electric-controlled injection device to be provided with a cavity near push rod one side, this cavity communicates with oil inlet pipe on the carburetor body; Oil nozzle on the solenoid valve electric-controlled injection device this mode of structure that directly communicates with trunnion, make this product with compact structure, rationally, make simply.Cooperate the mode that adopts taper mouth and taper platform between last push rod and the oil nozzle, can control the delivery volume of oil more accurately.
Below in conjunction with accompanying drawing the present invention is done further setting:
