Abstract
A scroll fluid machine has a low-pressure stage compression part for compressing a fluid sucked in from the outside between mutually overlapping wrap portions of two scroll members performing a relative orbiting motion and a high-pressure stage compression part for compressing the fluid sucked in from the low-pressure stage compression part between mutually overlapping wrap portions of two scroll members performing a relative orbiting motion. The scroll members in the low-pressure stage compression part have a larger radial gap between the wrap portions than that of the scroll members in the high-pressure stage compression part.
Claims5
A scroll fluid machine comprising:
- a low-pressure stage compression part for compressing a fluid sucked in from an outside between mutually overlapping wrap portions of two scroll members performing a relative orbiting motion;
- and
- a high-pressure stage compression part for compressing the fluid sucked in from said low-pressure stage compression part between mutually overlapping wrap portions of two scroll members performing a relative orbiting motion;
- wherein the scroll members in said low-pressure stage compression part have a larger radial gap between said wrap portions than that of the scroll members in said high-pressure stage compression part.
