Abstract

The utility model relates to a carburetor, in particular to a carburetor for petrol engine including a body of the carburetor, a main fueler, a low speed fueler, a starting apparatus, an air control shutter and an oil conduit interface. The low speed adjusting spindle sinks in the adjusting hole of the low speed fueler base; the automobile carburetor adjusts the position of the low speed adjusting spindle before leaving the factory when using the carburetor, the adjusting spindle sinks in the adjusting hole, thereby the adjusting spindle is not easy to be adjusted and the oil supply stability is ensured.

Description

Gasoline engine carburetor

Technical field

The utility model relates to a kind of Carburetor, particularly a kind of gasoline engine carburetor.

Background technique

Existing gasoline engine carburetor, consisted essentially of the Carburetor body, main oil supplying device, the idling oil supplying device, starting arrangement, closure and rail interface etc., its idling partly is adjustable, this Carburetor is the basis state of the art good with Engine Matching before dispatching from the factory, mixing adjusting spindle and throttle opening adjusting screw to the control idling are regulated, make Carburetor when engine oil, the ratio of fuel oil and air reaches best hybridization, but because the adjusting operating end 31 (being tail end) of current idle spindle 3 all is the pedestal outer (as shown in Figure 1) that is exposed to the idling oil supplying device, regulate the operating end in addition and be provided with the groove 32 that a word is opened, after Carburetor dispatches from the factory like this, the user just can be to its regulated at will with general screw-driver, the matching status of Carburetor will change so, thereby influenced the performance of motor, cause the engine operation instability, toxic emission can not get better controlled.

Summary of the invention

The purpose of this utility model is the deficiency that solves above-mentioned gasoline engine carburetor, and provides a kind of Carburetor to be difficult for the gasoline engine carburetor of the safety of regulated at will at the back idle spindle that dispatches from the factory.

The purpose of this utility model is achieved by the following technical solution: a kind of gasoline engine carburetor, include Carburetor body, main oil supplying device, idling oil supplying device, starting arrangement, closure and rail interface, the idle jet place of idling oil supplying device is provided with the idle spindle, and described idle spindle is submerged in the adjustment hole of idling oil supplying device pedestal.

The outer end that the utility model further is set to described idle spindle adjustable side is provided with jam and embedding is pressed in the adjustment hole.

The utility model further is set to the adjustable side of described idle spindle again for being with the round table-like of unfilled corner.

The beneficial effects of the utility model are: gasoline engine carburetor is adjusted the position of idle spindle earlier before dispatching from the factory, and in use, be submerged in the adjustment hole owing to regulate spindle, be not easy to be conditioned, guaranteed the stability of idling fuel feeding so regulate spindle.

Embodiment

Now accompanying drawing is further described the utility model in conjunction with the embodiments, and certain protection domain of the present utility model is not limited to the embodiment in the accompanying drawing.

As shown in Figure 2, a kind of gasoline engine carburetor embodiment of the utility model, include the Carburetor body, main oil supplying device, the idling oil supplying device, starting arrangement, closure and rail interface, idle jet 5 places of idling oil supplying device are provided with idle spindle 3, described idle spindle 3 is submerged in the adjustment hole 2 of idling oil supplying device pedestal 1, gasoline engine carburetor is adjusted the position of idle spindle 3 earlier before dispatching from the factory, and in use, because regulating spindle 3 is submerged in the adjustment hole 2, so regulating spindle 3 is not easy to be conditioned, thereby the ratio that makes fuel oil and air keeps best hybridization state, has guaranteed the stability of the work of motor.

The outer end of described idle spindle 3 adjustable sides 33 is provided with jam 4 and embedding is pressed in the adjustment hole 2, jam 4 the further adjusting spindle of having protected is set.

Adjustable side 33 as Fig. 3,4 described idle spindles 3 is the round table-like of band unfilled corner 34, such shape makes and can't open with general purpose tool that desire is regulated and must be used special tool, thereby has further guaranteed Security, obvious, also can use other nonstandard shapes.
