Abstract
A scroll compressor includes fixed and orbiting scrolls. The fixed scroll includes a fixed scroll end plate and a spiral fixed wrap extending from the end plate. The orbiting scroll includes an orbiting scroll end plate and an orbiting wrap extending from the end plate and engaging with the fixed wrap to form compression chambers. The fixed wrap includes a first fixed wrap portion on a radially outer side and a second fixed wrap portion on a radially inner side. The first fixed wrap portion is periodically covered by the orbiting scroll end plate and the second fixed wrap portion is always covered by the orbiting scroll end plate while the scroll compressor is operating. A sealing member is provided on one of the first fixed wrap portion and a first covering portion of the orbiting scroll end plate corresponding to the first fixed wrap portion.
