Peristaltic compressors and vacuum pumps

Abstract

This invention designs a mechanism similar in operation to a conventional rotary compressor, but with a completely new structure, which can be used as a compressor or vacuum pump. The main feature is a peristaltic rotor housed within a hollow outer casing. The peristaltic rotor maintains continuous rolling contact with the inner edge of the casing, forming a completely sealed compression chamber. Through the spatial changes created during their operation, various working fluids can be compressed or transported, achieving high pressure output at low operating speeds or the results of a high-vacuum vacuum pump. This solves the problem of conventional rotary compressors requiring a distance between the eccentric wheel and the outer casing, making them unsuitable for fully dry, oil-free compressors or vacuum pumps. This significantly improves operating efficiency and energy saving, while reducing manufacturing difficulty.
