Abstract
The utility model relates to an automobile carburetor. The utility model comprises an upper body, a center body, and a lower body, wherein, the center body comprises a small hollow throat, a main jet tube, an idle speed metering orifice, an air metering orifice, an oil float, a mechanical enrichment device, an oil storing chamber, and an accelerating pump; a vacuum enrichment device is removed in the oil storing chamber, and a main metering orifice which is arranged in the oil storing chamber can synchronously control an oil saving valve device. The utility model adopts the structure of the limiting metering orifice of a ball valve, and the limiting metering orifice of a ball valve is composed of a spring, a ball valve, an ejector rod, and the limiting metering mouth of the main metering orifice. The utility model which has the advantages of novel design, artful structure, easy manufacture, and high durability and saves about 24 % of fuel oil through actual measurement is a novel automobile carburetor which is suitable for various home-made automobiles.
Description
The utility model belongs to a kind of automobile carburetor.
There are many deficiencies in the Carburetor of motor car engine use at present, and claimant of the present utility model once invented a kind of improved automobile carburetor, and on May 20th, 92, application number was 91207173.7 by the Decree of Patent Office of China.The machining accuracy of the piston type oblique angle oil groove of above-mentioned automobile carburetor is difficult to guarantee that piston is easy to wear, thereby has shortened the working life of Carburetor.The claimant has done further improvement at above-mentioned defective to Carburetor.
The purpose of this utility model provides a kind of further improved automobile carburetor, it not only has the advantage of the intrinsic Carburetor of claimant, as engine oil metering-orifice and watt level are mated, the accelerating pump oil spout is controlled, the oil plane keeps stable, save advantages such as gasoline, and overcome former Carburetor vital part and be difficult to processing, the shortcoming that is easy to wear and tear.
Structure of the present utility model is to be made of upper body, middle body, lower body, body comprises middle trunnion, main jet pipe, idle metering jet in described, air jet, oil float, mechanical enrichment-system, reservoir and accelerating pump, remove vacuum controlled economizer in the described reservoir, and be provided with the controlled synchronous economizer valve device of main jet.The controlled synchronous economizer valve device of above-mentioned main jet, be to adopt the ball valve hole structure of limiting the quantity of, valve seat is an end enclosed type body, be fixed in the reservoir base plate and stretch out base plate, controlled synchronous economizer valve is fixed in valve seat one end with the gong line, controlled synchronous economizer valve is made up of spring, ball valve, push rod and the main jet mouth of limiting the quantity of, and depression bar and spring are housed on the accelerating pump connecting sheet.
The utility model has also overcome former Carburetor vital part and has been difficult to processing, the shortcoming that is easy to wear and tear except that the advantage with former design Carburetor, thereby the producer that is more convenient for produces in batches, and reduced cost, product is durable in use, saves fuel oil after tested and reaches about 24%.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a body structure sectional view in the utility model.
With reference to accompanying drawing, during startup, step pull bar 16, make accelerating pump connecting sheet interlock depression bar 7, depress push rod 6, open ball valve 4, make fuel oil through 8 ejections of main jet pipe.When motor need be loaded at full speed, will speed up pull bar 16 and continue to step downwards, make mechanical enriching depression bar 10 depress push rod 19, allow mechanical enrichment-system fuel feeding, spray through the main jet pipe.When motor did not need fuel feeding, as long as decontrol gas pedal 20, pull bar 10 rose to the top, and at this moment closure 17, upgrading valve 9 and the controlled synchronous economizer valve 1 of main amount all are in closed condition, made that fuel oil is unlikely to be wasted.
Claims (3)
1, a kind of automobile carburetor comprises upper body, middle body and lower body, and body comprises small venturi, main jet pipe, idle metering jet, air jet, oil float, mechanical enrichment-system, reservoir and accelerating pump in it is characterized in that.
2, according to claim 1, it is characterized in that having removed vacuum controlled economizer in the reservoir, and be provided with the controlled synchronous economizer valve device of main jet.
