Embodiment Construction
[0013] like figure 1 , 2 , 4, the main part of the present invention is a cylindrical cylinder 1 and the internal structure of the cylinder 1, in the cylindrical cylinder 1, there are n dividing plates 2 coaxially fixed on the inner wall of the cylinder 1, the n A partition 2 divides the inner chamber of the cylinder 1 into n small chambers in the axial direction. The central shaft 4 stretches into the cylinder body 1 from the outside of one end of the cylinder body 1 and is fixed on the other end of the cylinder body 1, and the central shaft 4 passes through the central holes of n dividing plates 2 in the cylinder body 1. A circular through hole 10 is processed on the other end surface of the cylinder body 1, and the circular through hole 10 communicates the additional air chamber with the main air chamber through a pipeline. Wherein, the first partition 2 is closely attached to the other end surface of the cylinder body 1 .
[0014] There is a fan-shaped through-hole 3 at...
