Abstract
A high pressure dome scroll compressor includes a compression mechanism having fixed and orbiting scrolls to form a compression chamber, a casing housing the compression mechanism, and first and second passage members. The first and second passage members guide low and intermediate pressure fluid from outside of the casing to the compression mechanism. The fixed scroll has a fixed end plate, a fixed wrap, and an outer peripheral wall surrounding the fixed wrap. The fixed end plate has suction and injection passages connected with the first and second passage members to guide the low and intermediate pressure fluid to the compression chamber. The fixed end plate has an attachment portion to which the first and second passage members are attached. The attachment portion is part of a back surface of the fixed end plate and protrudes on the back surface of the fixed end plate.
