The working process of suction, compression and discharge in the claw-type fluid machine was analyzed. To obtain the leakage law of the claw-type fluid machine~ compression process and the mixing process under different clearance, the variable mass thermodynamics system and numerical simulation method were used to investigate the changing rules between the state parameters, such as pressure and mass of the compression chamber, and the meshing clearance of rotating seal faces. The results help to the claw-type fluid machine＇s design, processing, assembly and improving the performance of fabrication.
