Abstract
A rotary compressor includes a cylinder, a drive unit, a piston, a vane, and an oil passage. The cylinder includes a suction chamber for suctioning fluid and a compression chamber for compressing fluid. The drive unit rotates a drive shaft by connecting to the cylinder. The piston oscillates in the cylinder by connecting to the drive shaft. The vane extends between the cylinder and the piston so as to separate the suction chamber from the compression chamber, and some parts of the length of the vane are inserted into a slide groove formed in the cylinder. One end of the vane is connected to the coupling groove formed in the piston. The oil passage is disposed between one end of the vane and the rolling piston so as to receive oil therethrough.
