Description
Technical Field
The utility model relates to a carburetor field, concretely relates to stable carburetor of idle speed.
Background
The carburetor is a mechanical device which mixes gasoline/liquefied gas with air in a certain proportion under the action of vacuum generated by the operation of an engine. The carburetor is a precise mechanical device, the important action of the carburetor on the engine can be called as the heart of the engine, when the carburetor is in a high-speed working state, liquefied gas enters a mixing cavity of a carburetor body from an air inlet pipe, air enters the mixing cavity through a choke valve, the liquefied gas and the air are mixed in the mixing cavity to form mixed gas, the mixed gas enters the engine from a throttle valve, in the idling working state, the air enters the mixing cavity from an idling channel arranged on one side of the choke valve of the carburetor body or an idling through hole arranged on the choke valve, the minimum opening degree of the throttle valve is adjusted through an idling control device, the mixed gas which maintains the minimum working value of the engine in the engine during idling is supplied, the engine is kept to work, idling stop is prevented, but after the carburetor is used for a period of time, the hole capacity of the idling gas is easy to block, and the idling, the problems of unstable idling, idling stop or over-high idling and the like are caused.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to solve the above-mentioned deficiencies of the prior art,
a carburetor with stable idling is provided.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a stable carburetor of idle speed, includes the carburetor body, is provided with the air outlet cavity who link up the setting in the carburetor body, be provided with the air inlet return bend directly over the throat on the carburetor body, air inlet return bend and air outlet cavity intercommunication set up, the side of carburetor body is equipped with adjusting bolt, and the side of carburetor body is close to one side position department of adjusting bolt and installs the throttle shaft, is provided with the throttle valve on the throttle shaft, and the throttle valve is located the one end of air outlet cavity, the carburetor body opposite side is provided with the choke valve axle, and the choke valve axle is provided with the choke valve in air outlet cavity, and the carburetor body is provided with throttle valve adjusting screw in the throttle valve corresponding position, its characterized in that: the air outlet cavity is provided with an idling air outlet through hole at one end of the throttle valve far away from the choke valve, and an idling auxiliary air outlet structure is arranged between the carburetor body and the idling air outlet through hole.
By adopting the technical scheme, when the carburetor is in a high-speed working state, the choke valve shaft is linked with the choke valve to open, the choke valve is opened to a position parallel to the air outlet cavity, and the throttle valve shaft is linked with the throttle valve to open, so that when the throttle valve is parallel to the air outlet cavity, the choke valve and the throttle valve are both opened to the maximum position, the air flow also reaches the maximum, air enters the air outlet cavity from the choke valve, fuel gas enters the air outlet cavity from the air inlet bent pipe, the air forms mixed gas with the fuel gas when flowing to the position corresponding to the air outlet cavity and the air inlet bent pipe, the mixed gas flows to the engine from the throttle valve, when the carburetor works at an idle speed, the choke valve is still opened, the air enters the carburetor body from the air outlet cavity, the fuel gas inlet bent pipe flows in, the opening angle of the throttle valve can be controlled by the idle speed adjusting screw, the air flow is, cause the unstable and idling stop's of idle speed problem easily after the carburetor uses a period, consequently the utility model discloses an one end that the choke valve was kept away from to the air outlet chamber that is located the throttle valve at the carburetion body sets up the idle air inlet hole, sets up the supplementary structure of giving vent to anger of idle speed between idle air inlet hole and the carburetor body, guarantees even be in under the idle state still to give vent to anger the structure through the supplementary structure of giving vent to anger of idle speed and guarantees that there is sufficient mixed gas flow to the engine, and engine when giving the idle speed supplies with sufficient gas mixture, guarantees that the engine.
An idle-stable carburetor of the above type may be further configured such that: the idle speed is assisted and is given vent to anger the structure including the idle air outlet channel of one end and outside intercommunication other end and air inlet elbow intercommunication, idle air outlet channel is located the one end that the air outlet chamber is close to the throttle valve, idle air outlet hole one end and air outlet chamber intercommunication other end and idle air outlet channel intercommunication set up.
Adopt above-mentioned technical scheme, when the carburetor is in idle operating condition, because the throttle valve, still open very little angle and make the air inflow engine under idle adjusting screw's effect, nevertheless probably cause the idle unstability after the carburetor uses a period, idling stop, and the utility model discloses a set up the idle air outlet channel of one end and outside intercommunication other end and air inlet elbow intercommunication at the one end that the air outlet cavity is close to the throttle valve, idle air outlet hole one end and air outlet cavity intercommunication other end and idle air outlet channel intercommunication set up, when the idle, the gas is from air inlet elbow through idle air outlet channel flow direction idle air outlet hole to flow into in the engine.
An idle-stable carburetor of the above type may be further configured such that: and a steel ball is arranged at one end of the idle air outlet channel communicated with the outside.
Adopt above-mentioned technical scheme, through set up the steel ball in this department, prevent that the gas from flowing out and not flow into in the engine from this department.
The utility model has the advantages that: the idling air outlet channel and the idling air outlet through hole are arranged, so that the carburetor can still supply enough fuel gas to the engine when idling, the idling is stable, and the idling stop of the engine is prevented.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
