Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the utility model offers in cylinder body 1 is sequentially connected the first logical air cavity 5, power cavity 6
With the second air cavity 9；One stage of compression piston 4 is equipped with first air cavity 5, as shown in Fig. 3, Fig. 4 and Fig. 5, is opened in one stage of compression piston 4
Provided with the first air admission hole 14 and steam vent 13, the first air admission hole 14 connects the first air cavity 5 and power cavity 6, on the first air admission hole 14
First valve block 12 is set；Two-stage compression piston 8 is equipped with second air cavity 9, as shown in Figure 6 and Figure 7, is opened on two-stage compression piston 8
If the second air admission hole 16, the second air admission hole 16 is connected with steam vent 13, sets the second valve block 15 on the second air admission hole 16, second
Gas outlet 2 is opened up in the side wall of air cavity 9, resilient plug 10 is installed on gas outlet 2；Suction nozzle 3 is set on power cavity 6, in power cavity 6
