The possibility combination of different types of chamber is described in Fig. 4 A to Fig. 4 G. This, it is noted that is for angle, 01, 02, 0�nd 04, there are several possible and they are not necessarily equal. Finally, also it should be pointed out that although the case where not being the configuration of attached drawing, chamber should not fully comply with each other, and this can be in angle It is asymmetric or other it is asymmetric in the case of occur.Further, it is to be noted that in Fig. 4 D to Fig. 4 G, second chamber 41b's Air intake passage 42b is positioned closer to the yam outlet 43 of second chamber 41b.Herein, it should be further noted that in Fig. 4 G In, since the yam outlet of first chamber 41a can continuously lead to the yam entry of second chamber 41b, chamber passageway it is not required clear existing. Two chambers 41a and 41b are both provided with air intake passage 41a and 42b, but the two air intake passages are differently Positioning so that the two air intake passages generate substantially tangentially but the opposite air-flow in direction of rotation in the chamber. First chamber 41a it is provided with yam entry 44 and ends at second chamber 41b via chamber passageway 45, wherein second chamber 41b is in the other end With yam outlet 43.
