Abstract
The invention discloses the integral type oil vacuole carburetors started suitable for various operating modes, and including carburetor body, oil vacuole is connected on carburetor body；Vacuum metering-orifice is equipped in air balance hole on carburetor body；The operating method of the integral type oil vacuole carburetor, it is specific as follows：Engine is when cold starts, pressing 13 times is carried out to oil vacuole, compressed air enters float chamber from pressure hole, the inside of float chamber is due to the throttling action generation positive pressure of vacuum metering-orifice at this time, positive pressure squeezes gasoline, for the indoor gasoline of float because the main jet pipe that pressure is acted through in carburetor body is extruded in the trunnion and mixing chamber being ejected into carburetor body, the cold startup for engine provides suitable gasoline, and engine can be made smoothly to start in cold.The present invention solves the problems, such as idling startup, and operational convenience is brought to user.
Description
Technical field
The present invention relates to Manufacturing Technology for Carburetors field more particularly to a kind of integral type oil vacuoles started suitable for various operating modes
Carburetor and its operating method.
Background technology
It during general startup engine is required for that carburetter choke is turned off manually, needs to open choke manually after startup,
Choke is manual control, and mode of operation is extremely inconvenient.Referring to the patent No. 201020273611.0, a kind of entitled carburetion
Device and its choke valve control mechanism, the conventional carburetor of Figure of description, when starting engine, choke is fully closed shape
State needs manually to drive Air strangler spindle Unscrew choke by rotating shift fork after startup, after engine is shut down, next time
When cold starts, and artificial closing choke is needed, opened again after startup, complicated, cost is higher.
Conventional belt choke flap structure carburetor needs first to close choke before starting, sometimes fully closed, sometimes half-open, difficult
With control, and choke was opened rapidly in 2-3 seconds after starting, otherwise engine can stop working because air capacity is very little.
The problem of conventional belt choke flap structure carburetor is difficult normal startup under idling operation, and fuel delivery is insufficient.
Invention content
A kind of simple in structure, operation side is provided it is an object of the invention to overcome above-mentioned shortcoming of the prior art
Just, practical the integral type oil vacuole carburetor and its operating method that are suitable for the startup of various operating modes.
The present invention realizes in the following way：
The integral type oil vacuole carburetor started suitable for various operating modes, it is characterised in that：Including carburetor body, describedization
It is connected with oil vacuole on oily device ontology, the pressure hole on the oil vacuole is connected with the float chamber on carburetor body；The carburetion
Vacuum metering-orifice is equipped in air balance hole on device ontology；The vacuum metering-orifice is connected with air balance hole.
A kind of operating method of the integral type oil vacuole carburetor started suitable for various operating modes, it is characterised in that：Specifically such as
Under：
Integral type oil vacuole carburetor is connected on engine, engine carries out pressing 1-3 when cold starts, to oil vacuole
Secondary, compressed air enters float chamber from pressure hole, at this time the inside of float chamber due to vacuum metering-orifice throttling action generate positive pressure,
Positive pressure squeezes gasoline, and the indoor gasoline of float is because the main jet pipe that pressure is acted through in carburetor body is extruded being ejected into
The intrinsic trunnion of oily device and mixing chamber in, the cold startup for engine provides suitable gasoline, engine can be made to exist
Smoothly start in the case of cold.
The beneficial effects of the present invention are：1st, this structure cancels original choke knot compared with original traditional carburetor
Structure uses oil vacuole structure instead；Structure operation is simple, as long as pressing oil vacuole 1-3 times according to varying environment operating mode before starting, nothing after startup
Need any operation engine that can automatically return to normal condition；2nd, petrol was provided to carburetor by oil vacuole structure, it is perfect
Ground solves the problems, such as that conventional belt choke flap structure carburetor is difficult normally to start this under idling operation；Operation is brought to user
On convenience.

Specific embodiment
Below by specific embodiment, and with reference to attached drawing, technical scheme of the present invention is described in further detail.It should
Work as understanding, embodiments of the present invention are not limited to the following examples, the accommodation in any form done to the present invention
And/or change and fall within the scope of the present invention.
Embodiment：
A kind of integral type oil vacuole carburetor started suitable for various operating modes, as shown in Figure 1, Figure 2, Figure 3 shows, including carburetor
Ontology 1, is connected with oil vacuole 2 on carburetor body 1, and the pressure hole 21 on oil vacuole 2 is connected with the float chamber 11 on carburetor body 1
It is logical；Vacuum metering-orifice 31 is equipped in air balance hole 12 on carburetor body 1；Vacuum metering-orifice 31 is connected with air balance hole 12
It is logical.
A kind of operating method of the integral type oil vacuole carburetor started suitable for various operating modes, as shown in figure 3, specifically such as
Under：Integral type oil vacuole carburetor is connected on engine, engine carries out oil vacuole 2 pressing 1-3 times when cold starts,
Compressed air enters float chamber 11 from pressure hole 21, when pressing oil vacuole 2, has air pressure to enter in float chamber 11, because of vacuum
The venthole of metering-orifice 31 is smaller, and air pressure cannot balance at once, in float chamber 11 air pressure can drastically increase, the vapour in float chamber 11
Oil is because the main jet pipe 4 that pressure is acted through in carburetor body 1 is extruded the trunnion being ejected into carburetor body 1 with mixing
Interior, the cold startup for engine provide suitable gasoline, engine can be made smoothly to start in cold.
During implementation, as long as pressing oil vacuole 1-3 times according to varying environment operating mode before starting, start after startup without any operation
Machine can automatically return to normal condition；Petrol was provided to carburetor by oil vacuole 2, ideally solves conventional belt choke
Structure carburetor is difficult normally to start this problem under idling operation, and operational convenience is brought to user.
The foregoing is merely the embodiment of the present invention, are not intended to limit the scope of the invention, every to utilize this hair
The equivalent structure or equivalent flow shift that bright specification and accompanying drawing content are made directly or indirectly is used in other relevant skills
Art field, is included within the scope of the present invention.
