Scroll fluid machine with a pin shaft and groove for restricting rotation
摘要：
A fixed scroll (60) is provided with a pin shaft portion (70) which is formed in a cylindrical shape. Formed in a movable scroll (50) is a slide groove (80) which extends in the radial direction of the movable scroll (50). The pin shaft portion (70) of the fixed scroll (60) is engaged into the slide groove (80) of the movable scroll (50). During orbital movement of the movable scroll (50), the pin shaft portion (70) slidingly contacts a side surface of the slide groove (80), whereby rotation of the movable scroll (50) is restricted.
摘要（中）：

固定涡旋盘（60）具有形成为圆筒状的销轴部（70）。 形成在动涡旋盘（50）中的是沿动涡旋盘（50）的径向延伸的滑动槽（80）。 固定涡旋盘（60）的销轴部（70）与动涡旋盘（50）的滑动槽（80）接合。 在可动涡旋件（50）的轨道运动期间，销轴部（70）滑动地接触滑动槽（80）的侧面，从而限制动涡旋盘（50）的旋转。
