Disclosed is a vortex gas mechanism, comprising a vortex disk A (1) and a vortex disk B (2), wherein the distance between a vortex line centre of at least one vortex disk (1, 2) of the two vortex disks (1, 2) and a rotation axis of an eccentric shaft (31, 32) corresponding thereto is adjustably set, the vortex disk A (1) and the vortex disk B (2) are correspondingly and cooperatively arranged, a concave-convex structure A (91) is arranged on a side surface of a vortex body of the vortex disk A (1), a concave-convex structure B (92) is arranged on a side surface of the vortex body of the vortex disk B (2), and the concave-convex structure A (91) is engaged with the concave-convex structure B (92) in a non-fully rolling mode. Further disclosed is a compressor comprising the vortex gas mechanism, an expander and an engine. The vortex gas mechanism and the device using same have the advantages of small leakage amount of gas, small friction loss, high working efficiency and long service life. |
