Abstract

The utility model relates to a main oil supply system controlling oil injector apparatus for a carburetor, which is used on a gasoline locomotive. A control springs is arranged on the needle valve of the apparatus, and the needle valve is arranged in an upper valve body and a lower valve body. The lower end of the valve is coupled with the oil injecting hole of the primary mixing chamber of the middle part of an oil injecting body by a small oil chamber, and the upper end is connected with a linking mechanism by the upper valve body. A main oil channel is directly connected with an oil pipe on the upper cover of the carburetor. The utility model is suitable for an existing upper-arrangement and lower-sucking carburetor with a single cavity and two cavities. After the carburetor is provided with the utility model, the carburetor not only can overcome the defect of over baking oil for the existing carburetor and reduce oil consumption, but also can cause fuel oil to be well atomized and burnt fully and relieve environment pollution.

Description

Carburetor is a control injector body device with main fuel feeding

It is control injector body device with main fuel feeding that the utility model relates to a kind of Carburetor usefulness, particularly gasoline locomotive Carburetor.

Carburetor is the important component part of gasoline locomotive fuel supply system.Put the single, double chamber of lower suction type Carburetor at present commonly used is, the main fuel feeding owner of this class Carburetor will be made of main air cavity, main jet hole and large, medium and small trunnion.All there is following shortcoming in the using process: 1, because main spray orifice does not have control gear, so fuel oil can not be effectively controlled, and gasoline is well atomized, it is insufficient to cause burning, not only waste fuel oil, and befouling environment, 2. to cause the fuel feeding surplus be the main cause of locomotive excessive fuel consumption to the multichannel fuel feeding.

The purpose of this utility model is at the prior art above shortcomings, a kind of Carburetor sheet is provided, particularly the gasoline locomotive Carburetor is a control injector body device with main fuel feeding, after existing Carburetor is installed the utility model, not only can make the good and fully burning of gasoline atomizing, alleviate environmental pollution, and the oil plant wasting phenomena of having avoided the multichannel fuel feeding to bring, greatly reduce oil consumption.

The purpose of this utility model is achieved in that Carburetor is a control injector body device with main fuel feeding, after it is characterized in that on the needle-valve of this device the pin control spring being installed, again needle-valve is installed in, in the following valve body, and the lower end of this needle-valve pass little grease chamber and with the nozzle opening mutually coupling of design at the primary mixing chamber at injector body middle part, the upper end of needle-valve is passed upper valve body and is linked to each other with linked system, the sidewall outside design of injector body has air passageways, the sidewall of primary mixing chamber base promptly is fixedly mounted on the outside of air passageways, one end of main oil gallery directly feeds little grease chamber, the other end directly links to each other with oil pipe on the carburetor cover, and design has several uniform gasification oil outlets on the primary mixing chamber base.

During use, the utility model is installed in the central authorities of putting the big trunnion of lower suction type single-barrel carburetor on existing, the big trunnion of twin barrel carburetor master air cavity central authorities, promptly former in, the small venturi place, replace middle small venturi and main jet hole in the former Carburetor.

After Carburetor has been installed the utility model, in case main air cavity closure is opened, needle-valve just is raised by linked system, under the effect by the suction force in oil pump oil pressure and air cavity of the oil pipe on the carburetor cover, gasoline is sprayed from the spray orifice on the injector body with very fast speed, form vaporific to primary mixing chamber, and through base forms eddy current, further impacted and gasification from the keen draft in the air passageways of top again, above-mentioned then gas mixture enters big trunnion by the nozzle opening on the base and gasifies with air mixing once more, form the high-quality ignition mixture, make it abundant burning.

The utility model compared with prior art has the following advantages: 1, because the utility model has been installed needle-valve, its size and injection time by controlling primary mixing chamber nozzle opening fuel injection quantity with the linked system and the noticeable degree spring of closure, and since the utility model main oil gallery directly link to each other with oil pipe on the carburetor cover, utilize the pressure of oil pump to make the fuel oil of main oil gallery and little grease chamber remain certain oil pressure, make locomotive in advancing, fuel oil forms and sprays, fully gasified and burnt fully, saved fuel oil and alleviated environmental pollution; 2, because the utility model is the oil circuit of a sealing, the phenomenon of the vibrations of having avoided jolting, the natural fuel feeding that tilts to cause and too much fuel feeding greatly reduces oil consumption; 3, owing to the float chamber pasta the utility model is had no effect, so can not take place to have guaranteed the normal working life of parts because of the general malfunctioning phenomenon that causes fuel oil directly to enter cylinder or axle box of float chamber oiling valve.

With most preferred embodiment of the present utility model in detail the utility model is described in detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the utility model atomizing working principle schematic representation.

As shown in Figure 1, on the needle-valve 5 behind the suit one noticeable degree spring 7, be installed in, following valve body 8, in 6, the lower end of needle-valve 5 pass little grease chamber 4 and with the nozzle opening 17 mutually coupling of design at the primary mixing chamber 2 at injector body 3 middle parts, the upper end of needle-valve 5 is passed upper valve body 8 and is linked to each other with contiguous block 19, one end of butt hook 10 links to each other with contiguous block 19, the other end links to each other with Throttle Opening Control axle 11, one end of control pull rod 9 links to each other with Throttle Opening Control axle 11, the other end links to each other with throttle plate pin 1, the sidewall outside design of injector body 3 has air passageways 18, the sidewall of the base 16 of primary mixing chamber 2 promptly is fixedly mounted on the outside of air passageways 18, the bottom design of base 16 has several uniform gasification oil outlets 20, one end of main oil gallery 12 directly feeds little grease chamber 4, the other end directly links to each other with oil pipe 13 on the carburetor cover 15, and 14 is the support of main oil gallery 12.Carburetor of the present utility model has been installed, has been had that oil inflame is abundant, oil consumption is low, polluted little advantage.
