Title:
渦輪発生装置
Document Type and Number:
Japanese Patent JP6876974
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To restrain turbulence of an air current which is generated in a front surface side space during generation of a vortex ring.SOLUTION: In a piston 20, a through hole 22 penetrating through the piston 20 in an axial direction is formed, and the piston 20 includes a first valve 26 which closes the through hole 22 when the piston 20 is moved to a direction of an outlet 12, and opens the through hole 22 when the piston 20 is moved to a direction separating from the outlet. The through hole 22 is opened when the piston 20 is moved to the direction separating from the outlet, and thereby, gas from the outside can be prevented from flowing into the outlet 12, and the vertex flow in the reverse rotation can be prevented. Accordingly, turbulence of an air current in a cylinder can be restrained.SELECTED DRAWING: Figure 1
