seal, seal spring, Wankel compressor, kinematic analysis, force analysis


The successful fabrication of a miniature Wankel compressor relies on its seal performance.The factors that influence the seal of a miniature Wankel compressor mainly include axial double mechanical seal and apex seals.Axial mechanical seal depends on machining precision on the end face.In the compression cavity, the springs for seal flake on the Wankel rotor put pressure on cylinder ,which generates the desired amount of pressing force.When springs fails,high-pressure cavity and low-pressure cavity will be connected.Spring performance will directly affect the efficiency of a Wankel compressor.In this paper,we aim to introduce kinematic analysis of apex seals and force analysis of springs in a miniature Wankel compressor.
