Abstract

PURPOSE:To prevent the seizure at the sliding surfaces between scroll vanes of a scroll compressor, by forming a lubricating oil collecting groove in the surface of a shroud, and opening an oil supply passage at the bottom of the oil collecting groove in the manner that the oil supply passage is communicated with the end face of a fixed scroll vane. CONSTITUTION:An oil collecting groove 33 for collecting lubricating oil temporarily is formed in the upper surface of a shroud 21. This oil collecting groove 33 is an annular recess formed concentrically around a discharge port 24, and an annular land 34 is formed between the discharge port 24 and the oil collecting groove 33. Further, an oil supply passage 35 is formed at the deepest bottom of the oil collecting groove 33. Here, since the oil supply passage 35 is extended through the inside of a fixed scroll vane 23 in the axial direction and opened in the end face of the vane 23, it is enabled to prevent seizure of the sliding surfaces between the scroll vanes of a scroll compressor.
