Abstract
PURPOSE:To expand the use as well as to feed oil to a compression chamber to obtain a high vacuum by positioning an exhaust port apart from a container farther than a switch valve, while arranging the switch valve and the exhaust port almost at the opposite positions to the axis of a rotary shaft. CONSTITUTION:A scroll projection 1a is furnished at a disk 1b of a drive scroll 1, a discharge port 1c is furnished at an axis center O1, and a driving shaft 4 is projected upward. The compressed gas pushes up a valve 32 from the discharge port 1c, passes through a discharge hole 4b, and reaches to an atmospheric pressure chamber 10. A check valve 39 is opened by a plate spring 44, and the oil 43 is fed to a compression chamber 3 through oil passages 41 and 42. In this case, the oil passages 41 and 42 are linked to a common space between a bearing 17 and a seal 14, and the oil is once stored in the space. In such a way, the oil can be fed to the compression chamber securely and the bearing can be lubricated surely.
