Description
Technical field
The present invention relates to carburetor field more particularly to a kind of automatic control chokes of carburetor.
Background technique
Motorcycle, universal machine carburetor be made of ontology, float chamber, throttle valve device, choke etc..On ontology
It is provided with inlet chamber, mixing chamber, mixing chamber is the blending space of air, fuel oil.Choke is installed in inlet chamber,
Choke is in inlet chamber end, and the cold starting performance of engine can be improved in choke when closing.Air throttle is in mixing chamber
Chamber, for controlling inflammable gas-flow.Throttle valve device is made of throttle plate pin, throttle blade, lock-screw etc..
Choke is made of choke piece, resistance piece axle of the air door, Air strangler spindle fork.Choke plate shape is rectangle
Piece, one side protrusion arc side, choke piece area are less than ontology inlet chamber, there is a small amount of air inlet when meeting engine start, hinder
Air flap is fixed on Air strangler spindle, and Air strangler spindle passes through the corresponding axis hole of ontology, and gear chimb injection molding in Air strangler spindle top is solid
Fixed connection, axis upper brace are set there are two the chimb for being in an angle of 90 degrees, and gear pin is fixed on corresponding body outer surface, rotatable handle
When, two chimbs are limited by the gear pin of setting on the body, can only make 90 degree of rotations.
When engine cold starts, choke piece is in full-shut position, the intracavitary vacuum degree of the subsequent mixing chamber of choke piece
Increase, be conducive to engine and draw more fuel oils, a small amount of air by choke piece and ontology air inlet cavity gap notch air inlet,
The denseer combustion mixture of supply engine is conducive to engine cold starting, and manual operation choke door handle is primary after starting
Property jumps opening for 90 degree of choke piece, into nominal situation.The defect of this traditional structure is: manually control range
Be limited only to standard-sized sheet with it is fully closed, the operating point and the temperature change of engine that cannot be operated according to engine adjust choke in real time
Suitable opening and closing degree, when manually opening choke, often there is violent abnormal jitter phenomenon, too early or too late unlatching resistance in engine
Air door can all directly result in engine misses, but also engine consumption or discharge value liter caused by existing because of artificial maloperation
It is high.
How to make full use of these existence conditions to realize choke automation control and smooth unlatching, close is a problem.
Summary of the invention
It is simple it is an object of the invention to provide a kind of structure in place of overcoming the deficiencies in the prior art described above, it is practical
The automatic control choke of carburetor.
The present invention realizes in the following way:
A kind of automatic control choke of carburetor, it is characterised in that: including choke piece 2, choke bobbin 3,
Bracket 4, check valve shaft coupling 5, the choke bobbin 3 are connected on carburetor body 1, and choke bobbin 3 is relative to change
Oily device ontology 1 can be rotated；The choke piece 2 is set on choke bobbin 3, and choke piece 2 is located at the resistance of carburetor body 1
At air door；The check valve shaft coupling 5 is connected on carburetor body 1 by bracket 4；The air inlet of the check valve shaft coupling 5
End 51 is connected with vacuum tube, and the moved end 52 of making of check valve shaft coupling 5 is connected by connection sheet 6 with choke bobbin 3, unidirectionally
Valve shaft coupling 5 drives choke bobbin 3 to rotate, and then realizes that choke piece 2 beats Push And Release to 1 choke of carburetor body
It closes；
Check valve shaft coupling 5 is fixed on carburetion ontology 1 to keep choke piece 2 and carburetor body 1 by bracket 4
Choke it is in closed state；After engine start, the inlet end 51 of check valve shaft coupling 5 sucks vacuum, and it is logical to make moved end 52
Crossing connection sheet 6 drives choke bobbin 3 to rotate in the direction of the clock, and then choke piece 2 is driven to rotate, when choke piece 2 revolves
Go to the airintake direction upright position with the choke of carburetor body 1；After engine misses, check valve shaft coupling 5 is deflated
It drives choke bobbin 3 to rotate counterclockwise, makees moved end 52 by connection sheet 6 and drive choke piece 2 and carburetor body 1
Choke it is in closed state, get ready for next engine cold starting.
The choke bobbin 3 is equipped with fixing groove 31, and the choke piece 2 is connected by screw in fixing groove 31.
The beneficial effects of the present invention are: can be according to difference operating condition each in engine whole work process, and start
Machine vacuum suck situation of change different from cold to heat engine accurately controls the on-off action of choke in real time；Change tradition
Craft it is prominent open prominent impatency air door structure, realize choke by the different variation of engine speed, vacuum, operating point and in real time into
It goes and controls on-off action, choke opens and closes non-moment sudden opening and closing, but the rotation opening and closing seamlessly transitted, keeps mixing gas and oil dense
Degree is also the mutation of steady non sudden, reaches the function of control choke flap switch, meets carburetor supply engine difference work
The purpose of required best combustion mixture under condition improves engine complete machine the operation is stable performance.

Specific embodiment
Now in conjunction with attached drawing, a specific embodiment of the invention is described in detail:
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the automatic control choke of a kind of carburetor, including choke piece 2, resistance
Air door bobbin 3, bracket 4, check valve shaft coupling 5, choke bobbin 3 are connected on carburetor body 1, and 3 phase of choke bobbin
Carburetor body 1 can be rotated；Choke piece 2 is set on choke bobbin 3, and choke piece 2 is located at carburetor body 1
At choke；Check valve shaft coupling 5 is connected on carburetor body 1 by bracket 4；The inlet end 51 of check valve shaft coupling 5 with
Vacuum tube is connected, and the moved end 52 of making of check valve shaft coupling 5 is connected by connection sheet 6 with choke bobbin 3, check valve shaft coupling
Device 5 drives choke bobbin 3 to rotate, and then realizes choke piece 2 to the on and off of 1 choke of carburetor body.
Choke bobbin 3 of the present invention is equipped with fixing groove 31, and choke piece 2 is connected by screw in fixing groove 31.
Initial conditions: check valve shaft coupling 5 is fixed on carburetion ontology 1 to keep choke piece 2 and be changed by bracket 4
The choke of oily device ontology 1 is in closed state；After engine start, the inlet end 51 of check valve shaft coupling 5 sucks vacuum, makees
Moved end 52 drives choke bobbin 3 to rotate in the direction of the clock by connection sheet 6, and then choke piece 2 is driven to rotate, and works as choke
Airintake direction upright position (i.e. fully open position) of the door rotation of piece 2 extremely with the choke of carburetor body 1；Work as engine misses
Afterwards, check valve shaft coupling 5, which is deflated, drives choke bobbin 3 to rotate counterclockwise, makees moved end 52 by connection sheet 6 and drives resistance
Air flap 2 and the choke of carburetor body 1 are in closed state, get ready for next engine cold starting.
The present invention provides a kind of carburetors for controlling choke flap structure can by controlling the opening and closing of choke
It realizes control of the engine from starting, acceleration, deceleration, flame-out whole work process to choke, is in choke always
A kind of optimal aperture, carburetor can be supplied to the diluter combustion mixture of engine at this time, until choke standard-sized sheet.
The automatic control of choke can be achieved in the present invention, and according to the different operating points of engine, opens or closes in real time
Choke, the combustion mixture of ideal air-fuel ratio needed for supply engine difference operating point, can effectively reduce the dirt of engine
Object discharge is contaminated, the integral working of engine is improved.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
