<p>PURPOSE:To enhance compression efficiency contriving a seal function of fluid for the increase by forming one of the volute members in its outwind angle different between the internal periphery and the periphery adjusting a degree of swelling and hollowing. CONSTITUTION:A movable scroll is arranged being opposed facing to a fixed scroll, forming the second volute unit 10 opposed facing to and meshed with the first volute unit 7. The second volute unit 10 forms its outwind angles alpha1, alpha2 different between the internal periphery 25 of the volute unit 10 and its periphery 26. By suitably adjusting the outwind angle alpha, the second volute unit 10 adjusts its wall thickness T and a degree of hollowing and swelling the internal periphery 25 and the periphery 26, enabling a meshing condition in each part with the first volute unit 7 to be adjusted. Thus contriving the increase of seal function of fluid and the smoothness of meshing with the volute unit, compression efficiency can be enhanced.</p> |
