    • 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 to contact the roller (22) continuously; a first bearing (24) installed in the cylinder (21), for rotatably supporting the driving shaft (13); a second bearing (300) installed in the cylinder (21), for rotatably supporting the driving shaft (13) and guiding the fluid into the fluid chamber (29); discharge ports (26) communicating with the fluid chamber (29); and a valve assembly (400) having openings (411, 412) separated by a predetermined angle from each other, for allowing the openings (411, 412) to selectively introduce the fluid into the fluid chamber (29) through the second bearing (300) at a predetermined position of the fluid chamber (29) according to rotation direction of the driving shaft (13), the valve assembly (400) having a center (410a) which is eccentrically installed by a predetermined distance from a center of the cylinder (29).
    • 公开了具有两个压缩容量的旋转式压缩机。 旋转式压缩机包括:可顺时针和逆时针旋转的驱动轴(13),并具有预定尺寸的偏心部分(13a); 形成预定内容积的圆筒(21) 可旋转地安装在所述偏心部分(13a)的外圆周上以与所述气缸(21)的内圆周接触的辊(22),沿着所述内圆周进行滚动运动,并形成流体室(29)至 与内周一起吸入和压缩流体; 安装在所述气缸中的叶片(23),以连续地接触所述辊(22); 安装在所述气缸(21)中的用于可旋转地支撑所述驱动轴(13)的第一轴承(24); 安装在所述气缸(21)中的第二轴承(300),用于可旋转地支撑所述驱动轴(13)并将所述流体引导到所述流体室(29)中; 与流体室(29)连通的排出口(26); 以及具有彼此分开预定角度的开口(411,412)的阀组件(400),用于允许开口(411,412)通过第二轴承(300)选择性地将流体引入流体室(29) )在所述流体室(29)的预定位置处,根据所述驱动轴(13)的旋转方向,所述阀组件(400)具有中心(410a),所述中心(410a)偏心地安装在所述驱动轴 气缸(29)。
