Fig. 2 is the structural representation of the carburetor jet of the utility model embodiment.
Among the figure: 1. spindle, 2. regulate annular groove, 3. nozzle, 4. filler opening, 5. in spout, 6. main injection jet 7. protrudes step, 8. transition steps is quickened atomizing angle in 9., 10. into angle is expanded in oil-feed.
Embodiment
Below the utility model will be further described by embodiment.
See figures.1.and.2, a kind of fuel-saving type carburetor needle valve of the present utility model and nozzle, this spindle 1 is the taper body of rod that reduces gradually of diameter from top to bottom, which is provided with three grades of ladders, from top to bottom, the taper body of rod diameter of ladders at different levels reduces gradually, and inclination increases step by step, the insertion slot type location spindle that this spindle 1 is regulated annular groove 2 for the top is provided with, this nozzle 3 is a hollow cylindrical, and its endoporus is stepped, is provided with filler opening 4 on it successively, interior spout 5 and main injection jet 6, spout 5 internal diameters are below the 2.5mm in it, these main injection jet 6 internal diameters are greater than interior spout 5 internal diameters, and these filler opening 4 internal diameters equate that with interior spout 5 internal diameters the working diameter of this spindle 1 body of rod equates with interior spout 6 internal diameters of nozzle 3, this spindle 1 and nozzle 3 movable sockets, this nozzle 3 is sheathed on spindle 1 periphery.
With reference to Fig. 2, when this nozzle 3 is used for the internal-combustion engine motorcycle, spout 5 internal diameters are below the 2.5mm in it, when being used for the internal-combustion engine booster car, spout 5 internal diameters are below the 2.0mm in it, these nozzle 3 endoporus are provided with a transition steps 8 at interior spout 5 places, this transition steps 8 for from interior spout 5 places to main injection jet 6 direction internal diameters increase gradually for critical localisation that main injection jet 6 internal diameters equate between one section, this filler opening 4 to nozzle 3 endoporus between the interior spout 5 are the cylindrical shape that internal diameter equates with filler opening 4 internal diameters, the critical localisation that these transition steps 8 internal diameters equate with main injection jet 6 internal diameters to nozzle 3 endoporus between the main injection jet 6 are the cylindrical shape that internal diameter equates with main injection jet 6 internal diameters, main injection jet 6 sides of these nozzle 3 endoporus are provided with the interior acceleration atomizing angle 9 of inclination, filler opening 4 sides are provided with the oil-feed of inclination and expand into angle 10, and these nozzle 3 outer surfaces are provided with and protrude step 7.
