SCROLL TYPE COMPRESSOR IN WHICH AN OIL SEAL IS FORMED BETWEEN AN INVOLUTE WALL AND AN END PLATE CONFRONTING WITH THE INVOLUTE WALL IN AN AXIAL DIRECTION

摘要

There is provided a scroll type compressor usinglubricant oil and including a pair of scroll members (20,30) confronting with each other in an axial direction.Each of the scroll members has an end plate (22, 32)extending perpendicular to the axial direction and aninvolute wall (21, 31) having a first and a second axialend which are opposite to each other in the axial direction.The first axial end is connected to the end plate. Thesecond axial end confronts with the end plate of acounterpart one of the scroll members. In the scroll typecompressor, the second axial end has a shallow groove (26,36) with a depth for suitably holding therein the lubricantoil to form an oil seal between the second axial end andthe end plate that confronts with the second axial end.
