    • In a scroll compressor, an outer wall curve of a scroll lap of a fixed scroll and an inner wall curve of a scroll lap of an orbiting scroll are formed of involute curves whose basic circle radius is defined as “a”, an inner wall curve of the scroll lap of the fixed scroll and an outer wall curve of the scroll lap of the orbiting scroll are formed of involute curves whose basic circle radius is defined as “b”, and a value of a/b which is a ratio of the basic circle radius a and the basic circle radius b is set to a value exceeding 1.0 and less than 1.5. With this structure, a compression chamber formed on the side of the inner wall of the scroll lap of the orbiting scroll is compressed faster than a compression chamber formed on the side of the outer wall of the scroll lap of the orbiting scroll, and leakage loss during compression process can be reduced.
    • 在涡旋式压缩机中,涡旋盘的涡卷的外壁曲线和旋转涡卷的涡卷的内壁曲线由基本圆半径定义为“a”的渐开线曲线,内壁曲线 固定涡卷的涡卷和涡卷的涡卷的外壁曲线由基本圆半径定义为“b”的渐开线曲线形成,并且a / b的值为 基圆半径a和基圆半径b设定为超过1.0且小于1.5的值。 利用这种结构,形成在绕动涡卷的涡卷的内壁侧的压缩室比形成在绕动涡盘的涡卷的外壁侧的压缩室更快地被压缩,并且泄漏损失 在压缩过程中可以减少。
