Device.Generally, rotary valve carburetor has fuel oil, air hybrid channel, with hybrid channel at lateral cylindrical cavity in carburetion
Device body interior moves axially, and passes through the adjustable gaseous mixture flowing velocity by this shape chamber of rotation of rotary valve, the cylinder
Shape intracavitary, which is also equipped with, is fixed on spindle concentric with rotary valve on rotary valve, and spindle is extend into main body and rotary valve
Concentric fuel oil main burner, fuel oil main burner, which is equipped with, passes to the through-hole of cylindrical cavity, thus allow fuel oil from main burner phase
Logical measuring room flows into hybrid channel.Rotary valve is axially moved, and spindle can be moved relative to main burner, to change the combustion of main burner
Oil jet size, control flow into the fuel oil of cylindrical cavity and hybrid channel.Existing rotary valve carburetor is generally not provided with starting
Device, engine idling is run under rich, therefore oil consumption is big, and discharge is poor, and service life is short；Use rotary valve carburetor
Engine in starting process, usually by closing choke to half-open, air capacity is reduced, to increase mixing into engine
Gas concentration is closed, engine is made smoothly to start, operating procedure is complicated, is easy error.
Utility model content
The utility model is intended to solve one of above-mentioned technical problem in the related technology at least to a certain extent.For this purpose,
The utility model proposes a kind of operations simply, can quickly provide more denseer fuel and air Mixture so that engine opens
Lifting type rotary valve carburetor that is dynamic, improving engine performance, reduce disposal of pollutants.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of lifting type rotary valve carburetor, including carburetor body, fixed frame, starting device, the fixed frame are removable
It unloads and is arranged on carburetor body, the starting device includes that can be rotated around longitudinal axis to open or close the rotation of hybrid channel
Valve, be provided with the spindle concentric with rotary valve in the rotary valve, and rotary valve top, which is connected with, can drive it to rotate or promoted
Rocking arm, rotary valve pass through the through-hole in the middle part of fixed frame to connect, reset bullet are provided between rotary valve and fixed frame with the rocking arm
Spring is provided with the limiting section of protrusion on the rocking arm, and the limiting section is corresponded on fixed frame and is equipped with telescopic lever.
As an improvement of the above technical solution, the lever is screw, and fixed frame is equipped with the spiral shell with the screw fit
Line seat.
As a further improvement of the above technical scheme, it is gradually increased to offer depth for the rocking arm bottom, with through-hole
For the guide groove of the arc in the center of circle.
Further, the guide post being adapted with the guide groove size is fixedly installed on the fixed frame.
Further, it is provided with rubber pad between the rocking arm and fixed frame.
Further, the grip part convenient for holding is provided at the top of the rocking arm.
The utility model has the beneficial effects that：The lifting type rotary valve carburetor of the utility model can drive rotation by rocking arm
Rotary valve is rotated or is promoted, easy to operate, and the air capacity into carburetor can be quickly adjusted according to actual demand, increases air and combustion
Oily channel provides fuel, the air Mixture of controllable enriching, can greatly improve engine cold starting or cold cranking capacity
Energy.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the explosive view of the utility model embodiment；
Fig. 3 is the rocking arm enlarged diagram of the utility model embodiment.
Specific implementation mode
Referring to figs. 1 to Fig. 3, a kind of lifting type rotary valve carburetor of the utility model, including carburetor body 1, fixation
