    • A scroll fluid machine in which, even if volute bodies on the orbiting side and on the fixed side are different in material from each other, the volute bodies can be brought to their respective strengths equal to each other, dimension can be miniaturized or reduced, and internal leakage is reduced so that an attempt can be made to improve performance. In the scroll fluid machine, a curve of either one of an orbiting outward curve and a orbiting inward curve of a volute body on the orbiting side is formed by an algebraic spiral expressed by the following equation in the form of polar coordinates r=a.multidot..theta..sup.k (here, r: radius vector, .theta.: angle of deviation, a: coefficient, k: exponent). This curve and any one of a fixed outward curve and a fixed inward curve of the volute body on the fixed side are arranged with a phase difference of about 180 degrees. Thicknesses of respective volute walls on the orbiting side and on the fixed side are adequately or suitably changed.
    • 一种涡旋流体机械,其中,即使旋转侧和固定侧的涡卷体在材料上彼此不同,也可使蜗壳体的各自的强度彼此相等,尺寸可以小型化或减小, 并且内部泄漏减少,从而可以尝试提高性能。 在涡旋流体机器中,绕轨道侧的涡卷体的轨道向外曲线和轨道内弯曲中的任一个曲线由以下等式表示的代数螺旋形成,该曲线以极坐标r = k(这里,r:半径向量,θ:偏差角,a:系数,k:指数)。 该曲线和固定侧的蜗壳体的固定向外曲线和固定向内曲线中的任一个布置有大约180度的相位差。 旋转侧和固定侧的蜗壳壁的厚度充分或适当地改变。
