固定涡旋体及涡旋式流体机械
摘要：
本发明的课题为使固定涡旋体低成本化，并且使固定涡旋体及旋回涡旋体相互间的定位容易。固定涡旋体（32）由分别制造的端板（32A）和支承体（32B）构成。端板（32A）由内侧端板（32Aa）、涡旋形状的涡卷部（32Ab）和形成在内侧端板（32Aa）的背面（33）上的冷却翅片组（52）构成。支承体（32B）在中心具有供内侧端板（32Aa）插入的圆形孔（32Ba），并一体地形成有收纳销曲柄机构（40）的外壳（39）。端板（32A）和支承体（32B）能够拆装地被结合在外壳（12b）的内部。在在旋回涡旋体（26）的外周端以及固定涡旋体（32）上分别一体地形成有外壳（39），该外壳（39）收纳销曲柄机构（40）。
摘要（英）：

The invention aims to realize low cost of a fixed scroll and easy positioning between the fixed scroll and a cycle scroll. The fixed scroll (32) is composed of an end board (32A) and a supporter (32B) which are respectively manufactured. The end board (32A) is composed of an inside end board (32Aa), a scroll-shaped spiral part (32Ab) and a cooling fin set (52) which is formed on the back surface (33) of the inside end board (32Aa). The center of the supporter (32B) is provided with a circular hole (32Ba) for insertion of the inside end board (32Aa), and furthermore a housing (39) which accommodates a pin crank mechanism (40) is integrally formed. The end board (32A) and the supporter (32B) are detachably combined in a casing (12b). The housing (39) is integraly formed on the outer periphery end of the cycle scroll (26) and the fixed scroll (32) respectively. The housing (39) accommodates the pin crank mechanism (40).
