Abstract

The utility model discloses an improved vehicle carburetor and in particular relates to the improvement of a plunger-type valve carburetor, which is characterized in that a regulating device of a main jet is additionally arranged on an existing carburetor. The regulating device is composed of a conical needle (2) of a bottom cover (8) and a regulating plug screw (3) which are matched. The conical needle (2) is inserted in a carburetor main jet (1) and the depth position that the conical needle (2) is inserted into the carburetor main jet (1) is regulated on the dependence of the regulating plug screw (3). Since the conical needle (2) is inserted into the main jet (1), the sectional area that oil materials of the main jet (1) pass is reduced firstly and the speed that the oil materials which are floated indoors easily and rapidly enter into a main jet tube to spray out through the main jet (1) is alleviated when a throttle is opened over fast secondly. Practice shows that after motorcycles use the carburetor of the utility model, gasoline each liter can drive for 10 kilometers additionally.

Description

Carbureter main jet is regulated enriching device

Technical field

The utility model belongs to a kind of improvement Motor Vehicle Carburetor, refers more particularly to the improvement of plunger type closure Carburetor.

Background technique

Plunger type closure Carburetor is made up of Carburetor matrix, float chamber and plunger spindle mechanism three parts.Carburetor main fuel feeding work system and structure are to be equipped with closure and main jet pipe and main jet on the Carburetor matrix, and a middle macropore is used for erection column plug valve and spindle mechanism.When plunger valve moved up and down, the suction tude throat circulation area in the Carburetor matrix increased thereupon or dwindles, and controls the air inflow of motor with this.Because spindle is connected one with plunger valve, spindle inserts in the main jet pipe.Spindle moves up and down with plunger valve, controls the oil mass that sprays with this from the main jet pipe.This is to have controlled the cardinal principle total amount that oil mass is supplied with according to working load, and for saving with oil, control is just meticulous inadequately.Especially Motor Vehicle manufacturer is the vehicle power abundance that the users to trust our factory is produced, and horsepower is big, the good use.Thereby, the fuel feeding of Carburetor is measured bigger safety factor, and make the main jet aperture often bigger than normal.When the main jet aperture was bigger than normal, the oil mass of main jet pipe ejection was inevitable on the high side, and the inflammable mixture concentration factor is less than normal, and fuel combustion is insufficient, and this just must cause the oil plant waste.

Summary of the invention

In view of above-mentioned analysis, for reaching the purpose of saving oil mass, the utility model improves existing plunger type closure Carburetor, has designed the adjustable Carburetor of a kind of main jet.It is made up of Carburetor matrix, float chamber and plunger spindle mechanism three big parts, it is characterized in that the controlling device of having set up main jet on existing Carburetor.Controlling device is cooperated and is formed by carbureter main jet and awl, adjustment plug screw.Awl inserts in the main jet.Come the cone governor pin to insert the depth in the main jet by adjusting plug screw.Size with control main jet sectional area.Its principle of saving oil mass is, owing to had awl to insert in the main jet, the one, reduced the sectional area that the main jet oil plant passes through; The 2nd, to open too fastly when excessive when plunger valve, the oil plant in the float chamber enters in the main jet pipe by main jet fast easily and sprays, and has had awl just to slow down its speed.Thereby reached fuel-efficient purpose.By practice test repeatedly, oil-saving effect is fairly obvious.With the motorcycle is example, do not use the utility model before, one liter of oil 40-45 kilometer that can only travel, use the utility model after, one liter of oil of most motorcycles 55-65 kilometer that can travel.

Description of drawings

Fig. 1 is the utility model embodiment one generalized section.

Fig. 2 is the utility model embodiment two a generalized section.Wherein: (1) is main jet; (2) be awl; (3) be to adjust plug screw; (4) be metal sleeve; (5) be the leakage proof nut; (6) be the metal flexible cord; (7) be the screens spring; (8) Carburetor bottom.

Embodiment

The contrast accompanying drawing is further described the utility model below.

Embodiment one, and awl (2) is made front fine and rear thick taper needle-like, adjusts plug screw (3) and is screw spike commonly used, and front end firmly connects awl (2) rear end, and sleeve pipe (4) is built-in with and adjusts the screw thread that plug screw (3) matches.Sleeve pipe (4) rear end periphery is equipped with the screw thread that matches with leakage proof nut (5).Leakage proof nut (5) inwall is equipped with and the outer internal thread that matches of sleeve pipe (4).During installation, in Carburetor bottom (8) bottom and aim at the carbureter main jet position and be drilled with a hole that adapts with sleeve pipe (4), sleeve pipe (4) is placed the hole, and be connected and sealed.The adjustment plug screw (3) that will connect awl (2) places in the sleeve pipe (4) and screw-in, and awl (2) is inserted in the main jet (1).To adjust plug screw (3) spinning in and out and regulate awl (2) and insert the depth in the main jet (1), the not only fuel-efficient but also good effect of amount that make well when regulating vehicle and use with this.Sleeve pipe (4) overcoat seal washer, leakage proof nut (5) is spun on the sleeve pipe (4), and screws the compacting seal washer, prevents seepage.

Embodiment two, consider that the leakage proof nut does not reach the leakage proof effect among the embodiment one, also consider simultaneously to be convenient to regulate.Thereby design implementation example two.Awl (2) is made front fine and rear thick cone needle-like, and sleeve pipe (4) is made the intestinal tube shape with metal, and sleeve pipe (4) upper pipes is built-in with and adjusts the screw thread that plug screw matches.The lower end of metal flexible cord (6) firmly is connected with awl (2), and the upper end firmly is connected with adjustment plug screw (3) lower end.Be inserted in screens spring (7) after connecting, insert in the sleeve pipe (4), stretch out in sleeve pipe to awl (2), the upper end is adjusted plug screw (3) and is screwed in sleeve pipe (4) screw thread.During installation, in the bottom (8) of Carburetor bottom, the seat over against the main jet (1) of Carburetor is drilled with the hole that adapts with sleeve pipe (4) caliber, and sleeve pipe and hole are for being tightly connected, and requirement can not have seepage.Awl (2) inserts in the main jet (1).Sleeve pipe (4) upper end firmly is connected the Carburetor matrix border.Sleeve pipe (4) upper end-hole requires to be higher than float chamber maximum oil face height.After installing, can test run, regulate awl (2) and insert depth position in the main jet (1) by adjusting plug screw (3).To reach the best effects that vehicle used and saved oil plant well.

Claims (3)

1, a kind of carbureter main jet is regulated enriching device.Be by the Carburetor bottom, awl and adjustment plug screw cooperate to be formed.

2, regulate enriching device by the described carbureter main jet of claim 1, it is characterized in that awl and adjustment plug screw firmly link into an integrated entity.

3, regulate enriching device by claim 1,2 described carbureter main jets and it is characterized in that the metal flexible cord has sleeve pipe outward.
