IPC: F04C18/02
Filed: 2000-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent lowering of performance by over compression in a scroll compressor used for an air conditioner for official and domestic uses. SOLUTION: An offset part 36 is arranged on a lap outside wall 31a in the vicinity of the beginning of the winding of the lap 31 of a movable scroll so as to thin the lap 31, so that a narrow clearance can be formed in a contact point of the lap 31 between a compression chamber and a discharge chamber with the lap of a fixed scroll.
