摘要： Disclosed is a rotary compressor having two compression capacities. The rotary compressor includes: a driving shaft (13) being rotatable clockwise and counterclockwise, and having an eccentric portion (13a) of a predetermined size; a cylinder (21) forming a predetermined inner volume; a roller (22) installed rotatably on an outer circumference of the eccentric portion (13a) so as to contact an inner circumference of the cylinder (21), performing a rolling motion along the inner circumference and forming a fluid chamber (29) to suck and compress fluid along with the inner circumference; a vane (23) installed elastically in the cylinder (21) to contact the roller (22) continuously; upper and lower bearings (24, 25) installed respectively in upper and lower portions of the cylinder (21), for supporting the driving shaft (13) rotatably and sealing the inner volume hermetically; an oil path configured to allow oil to uniformly flow between the bearings (24, 25) and the driving shaft (13); discharge ports (26a, 26b) communicating with the fluid chamber (29); suction ports (27a-c) communicating with the fluid chamber (29) and being spaced apart from each other by a predetermined angle; and a valve assembly (100) for selectively opening any one of the suction ports (27a-c) according to rotation direction of the driving shaft (13).
