Scroll compressor having an arcuate portion side surface clearance larger than a spiral portion side surface clearance

A scroll compressor comprising:

• a fixed scroll including a fixed scroll wrap;
• and
• a movable scroll including a movable scroll wrap,
• the fixed scroll wrap including
• a fixed spiral portion having a spiral shape, and
• a fixed arcuate portion having an arcuate shape, the fixed arcuate portion being smaller in radius of curvature than the fixed spiral portion,
• the movable scroll wrap including
• a movable spiral portion having a spiral shape, and
• a movable arcuate portion having an arcuate shape, the movable arcuate portion being smaller in radius of curvature than the movable spiral portion,
• an arcuate portion side surface clearance being
• defined by the fixed arcuate portion and one of the movable spiral portion and the movable arcuate portion at where the one of the movable spiral portion and the movable arcuate portion is in a closest proximity to the fixed arcuate portion, or
• defined by the movable arcuate portion and one of the fixed spiral portion and the fixed arcuate portion at where the one of the fixed spiral portion and the fixed arcuate portion is in a closest proximity to the movable arcuate portion,
• a first spiral portion side surface clearance being defined by the fixed spiral portion and the movable spiral portion at where the fixed spiral portion is in a closest proximity to the movable spiral portion, the first spiral portion side surface clearance being disposed radially outward of the arcuate portion side surface clearance,
• a second spiral portion side surface clearance being defined by the fixed spiral portion and the movable spiral portion at where the fixed spiral portion is in a closest proximity to the movable spiral portion, the second spiral portion side surface clearance being disposed radially outward of the first spiral portion side surface clearance,
• the arcuate portion side surface clearance being measured at a tip of one of the fixed arcuate portion and the movable arcuate portion, and
• the arcuate portion side surface clearance being larger than each of the first and second spiral portion side surface clearances.
