Abstract
In a scroll compressor, a sealing portion of a discharge cover placed between a suction spacer and a discharge space is formed to be spaced apart in an axial direction from a fixed scroll, whereby the discharge cover is in contact with a fixture in an axial direction only on a single circumference, facilitating fabrication and assembling of the discharge cover. Also, after assembly, when the discharge cover is pressurized toward the fixed scroll by a discharge pressure of a refrigerant discharged to the discharge space, the discharge cover does not transfer pressurization force to the fixed scroll, thus reducing a frictional loss between the fixed scroll and an orbiting scroll.
