    • A stator for an eccentric spiral pump comprises a hollow body of an elastic material which has a casing comprising a plurality of segments extending in a longitudinal direction of the casing. Adjacent segments are interconnected along longitudinal sides at variable angles to each other, so that the segments enclose an entire circumference of the casing. Surfaces of the segments are of a planar configuration, so that a closed casing of polygonal cross-section is formed by the interconnected segments. The hollow body of elastic material is of a matching polygonal cross-section to achieve positive contact with the casing.
    • 用于偏心螺旋泵的定子包括弹性材料的空心体,该空心体具有包括在壳体的纵向方向上延伸的多个区段的壳体。 相邻的区段沿着纵向侧面以可变的角度彼此相互连接,使得区段围绕壳体的整个圆周。 这些段的表面是平面构型,使得由互连的段形成多边形横截面的封闭的壳体。 弹性材料的中空体具有匹配的多边形横截面,以实现与壳体的正接触。
