Scroll compressor

摘要

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.

主权项

1. A scroll compressor, comprising:
a container having an inner space; a fixed scroll installed in the inner space of the container; an orbiting scroll installed to be engaged with the fixed scroll to make a gyrational movement; and a discharge cover that divides the inner space of the container into a suction space and a discharge space, wherein the discharge cover includes:
a sealing portion provided on a portion of the discharge cover that faces the fixed scroll, wherein the sealing portion is configured such that an upper surface of the fixed scroll and an end surface of the sealing portion are spaced apart from each other in an axial direction of the scroll compressor when the scroll compressor is stopped and is configured to seal the suction space from the discharge space;a support portion formed as a step on an inner circumferential surface of the discharge cover and supported on a main frame; anda fixing portion formed on an outer circumferential surface of the discharge cover and configured to support the container.
