ABSTRACT:
A rotary compressor for changing a compression capacity of the compressor includes a driving shaft being rotatable clockwise and counterclockwise, and having an eccentric portion of a predetermined size; a cylinder forming a predetermined inner volume; a roller installed rotatably on an outer circumference of the eccentric portion so as to contact an inner circumference of the cylinder; a vane installed elastically in the cylinder to contact the roller continuously; a first bearing installed in the cylinder, for rotatably supporting the driving shaft; a second bearing installed in the cylinder, for rotatably supporting the driving shaft and guiding the fluid into the fluid chamber; discharge ports communicating with the fluid chamber; and a valve assembly having openings separated by a predetermined angle from each other, the valve assembly having a center which is eccentrically installed by a predetermined distance from a center of the cylinder.
