2 air-spray 7（Shown in Fig. 1）.
Fig. 3 has the cross sectional shape of ellipse to the hollow needle 11 shown in Fig. 8（Shown in Fig. 5）, so as to provide
Broader side wall 14, the cumulative volume without increasing hollow needle 11.
As will be explained in more detail, cut using laser cutting technique in the basic hole 15 for forming outflow opening 13
Into the side wall 14 adjacent with the end 12 of hollow needle 11.
As can be most preferably seen in the figure 7, the passage section of each in basic hole 15 is outside hollow needle 11
Side 25 reduces to the inner side 26 of hollow needle 11.In other words, the passage section in basic hole 15 dissipates towards outside 25 so that flows through base
The compressed air in this hole 15 will be expanded before final be discharged.This expansion is for obtaining the air-spray 7 with high speed
（Shown in Fig. 1）For be favourable.
In Fig. 3 into the embodiment shown in Fig. 8, basic hole 15 is arranged to mosaic, and the mosaic is along hollow
The direction of the longitudinal axis 24 of pin 11 have several, i.e. seven stacked rows, wherein, near the end 12 of hollow needle 11
In a line of the mosaic of positioning, the basic hole 15 of a list is only disposed with.The basic hole 15 and every other basic hole 15
Oriented in the case of an end 12 towards hollow needle 11 in its side surface 17.
As can be most preferably seen in figure 3, basic hole 15 is arranged such that the encirclement shape of outflow opening 13 is near
It is similar to the shape of regular hexagon.
Fig. 9 to Figure 12 shows two alternate embodiments of the hollow needle 11 of the pilot jet 8 for Fig. 1, the hollow needle
11 have outflow opening 13, and the outflow opening 13 is made up of multiple basic holes 15 of the regular hexagonal section with modification, the base
This hole 15 is arranged close to each other in the side wall 14 of hollow needle 11.In Fig. 9 to Figure 12 embodiment, basic hole 15 is with six sides
The mosaic of shape is set, to make side surface be abutted with side surface along a plurality of line 20, i.e., along four lines 20 in Fig. 9 and Figure 10 with
And three lines 20 in Figure 11 and Figure 12.
Line 20 is arranged relative to the longitudinal axis 24 of hollow needle 11 with the angle between about 30 ° to about 60 °.Due to this
Kind arrangement, in use, Fig. 9 is crossed earlier when all basic holes 15 are than being arranged to relative 24 specular of longitudinal axis
With the lower warp thread plane indicated by the line in Figure 11（lower warp plane）21.
Figure 13 schematically shows the method for manufacturing hollow needle 11 using laser cutting device 22, the hollow needle
11 have the outflow opening 13 being made up of multiple basic holes 15.Using laser cutting device 22, each with least substantially six
Multiple basic holes 15 in the section of side shape are cut in side wall 14, wherein, basic hole 15 is arranged to the mosaic map mosaic of hexagon
Case, the mosaic has small isolation part 19 between basic hole 15, as shown in any figure in Fig. 3, Fig. 9 or Figure 11.
Laser cutting device 22, which is arranged to, guides laser beam 23 into hollow needle 11, hollow so as to which basic hole 15 is cut to
In pin 11, as schematically shown in Figure 13.
As shown in Figure 13, laser beam 23 is drawn towards the outside 25 of hollow needle 11.As a result, being cut into side wall 14
Basic hole 15 at the outside 25 of hollow needle 11 than having bigger size, in other words, base at the inner side 26 of hollow needle 11
