Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and working principle are done concrete description:
See also Fig. 1 and the utlity model has the carburetor structure schematic representation of startup enrichment-system and the A-A cut-away view of Fig. 2 Fig. 1.
As shown in the figure, the utility model comprises float chamber 5, trunnion 9, main jet pipe 8, main jet 7, balance duct 10, throttle orifice 11, also comprise the startup enrichment-system that connects the float chamber air cavity, this startup enrichment-system comprises startup bubble 2 and tracheae 3, starting bubble 2 is that pedestal and spring caps body constitute, a periphery of pedestal is provided with tongue, and another side is provided with the protruding hole that connects tracheae, and the both sides in protruding hole also are provided with fixed installation part 14; Be provided with aperture 1 on the top of spring caps body, the lower end is provided with and the corresponding flange of tongue, and the flange of the tongue of pedestal and spring caps body matches both are connected as a single entity.
Pedestal and spring caps body are not limited only to above-mentioned Placement, also the periphery of pedestal and the lower end of spring caps body can be provided with respective threads respectively, realize connecting.
The spring caps body is that rubber parts is made.
When sending out the machine machine and under low temperature environment, starting, finger 13 is pressed and is started bubble 2, finger is also blocked the aperture 1 that also starts on the bubble simultaneously, start bubble pressurized air and enter float chamber air cavity 4 by connecting tracheae 3, float chamber air cavity 4 is through balance duct 10, throttle orifice 11 communicates with atmosphere, because the throttling action of throttle orifice 11, advance the air of float chamber air cavity 4 from 2 compressions of startup bubble and the float chamber air cavity, set up enough pressure, this pressure acts on the pasta, make fuel oil in the float chamber 5 through the hole 6, main jet 7, spray into trunnion 9 and air mixing after air intake branch of the engine sucks cylinder by main jet pipe 8, for motor be provided at startup low temperature environment under required add rich mixture; (seeing Fig. 1, Fig. 2)
Motor is when proper functioning, and the aperture 1 that starts bubble communicates with atmosphere, and balance air one tunnel enters float chamber air cavity 4 through aperture 11, balance duct 10; One the tunnel through starting aperture 1 on the bubble, connecting tracheae 3 and enter float chamber air cavity 4, under the balanced action that starts aperture 1 this balance air flue on the bubble, avoided the harmful effect that balance is brought because of the throttling action of aperture 11;
In sum, the pressure pump oil principle that this device adopts the manual compression air to produce has realized that Carburetor starts the required rich mixture that adds for motor provides under low temperature environment, has solved Carburetor and start problems difficult, that the number of starts is many under low temperature environment.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
