    • A displacement machine for compressible media comprising a displacement compartment bounded by an inwardly situated spiral-shaped side wall and an outwardly situated spiral-shaped side wall, the displacement compartment describing a span angle which exceeds 360.degree. and extends from an inlet to an outlet. The displacement compartment is provided with a displacement element which carries out a circulatory movement relative to the displacement compartment and likewise possesses the shape of a spiral and has practically the same span angle as the displacement compartment. The displacement element, during the course of the circulatory movement, always contacts both the outer situated side wall and the inner situated side wall at least at one respective advancing contact line. A pole of a first section, spanning approximately 360.degree. both of the displacement compartment and the displacement element is off set from a pole of a likewise spiral-shaped second section which uniformly merges at the inner end of this first section by an amount which is smaller than the mean radius of curvature at the inner end of the aforementioned first section.
    • 用于可压缩介质的排量机包括由位于内部的螺旋形侧壁和向外定位的螺旋形侧壁限定的位移室,所述位移室描述跨度角超过360°并且从入口延伸到出口。 排量室设置有位移元件,该位移元件相对于位移室执行循环运动,并且同样具有螺旋形状并且具有与排量室几乎相同的跨度角。 位移元件在循环运动过程中至少在一个相应的前进接触线处总是接触位于外侧的侧壁和位于内侧的侧壁。 跨越大约360°的位移室和位移元件的第一部分的极点从同样螺旋形的第二部分的极点偏离,该极点在该第一部分的内端处均匀地合并一定量的量 小于上述第一部分内端的平均曲率半径。
