Description
Technical field
The present invention relates to a kind of carburetor, particularly a kind of lifting type rotary valve carburetor.
Background technology
Carburetor is the machinery that mixes a certain proportion of gasoline with air under the vacuum action that engine work produces
Device.Generally, rotary valve carburetor has fuel oil, air hybrid channel, with hybrid channel into horizontal cylindrical cavity in carburetion
Device body interior is axially movable, and passes through the adjustable gaseous mixture flowing velocity by this shape chamber of rotation of rotary valve, the cylinder
Shape intracavitary is also equipped with being 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, so as to change the combustion of main burner
Oil jet size, control flow into cylindrical cavity and the fuel oil of 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 into the mixed of engine
Gas concentration is closed, engine is smoothly started, operating procedure is complicated, easily error.
The content of the invention
It is contemplated that one of above-mentioned technical problem in correlation technique is solved at least to a certain extent.For this reason, this hair
It is bright to propose that a kind of operation is simple, quickly provide more denseer fuel and air Mixture so that engine start, raising are sent out
Motivation performance, the lifting type rotary valve carburetor for reducing disposal of pollutants.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of lifting type rotary valve carburetor, including carburetor body, fixed frame, starting device, the fixed frame are removable
Unload and be arranged on carburetor body, the starting device includes to rotate 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 lifting
Rocking arm, rotary valve are connected with the rocking arm through the through hole in the middle part of fixed frame, and reset bullet is provided between rotary valve and fixed frame
Spring, the limiting section of protrusion is provided with the rocking arm, and corresponding to the limiting section on fixed frame is equipped with telescopic lever.
As the improvement of above-mentioned technical proposal, the lever is screw, and fixed frame is equipped with the spiral shell with the screw fit
Line seat.
Further as above-mentioned technical proposal is improved, and the rocking arm bottom offers what depth gradually increased, 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 easy to grip is provided with the top of the rocking arm.
The beneficial effects of the invention are as follows：The lifting type rotary valve carburetor of the present invention can drive rotary valve to rotate by rocking arm
Or lifting, it is easy to operate, it quick regulation can enter the air capacity of carburetor according to the actual requirements, increase air and fuel gallery,
Fuel, the air Mixture of controllable enriching are provided, engine cold starting or cold starting performance can be greatly improved.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the embodiment of the present invention；
Fig. 2 is the explosive view of the embodiment of the present invention；
Fig. 3 is the rocking arm enlarged diagram of the embodiment of the present invention.
