Abstract: The present disclosure provides a rotary compressor including a cylinder having an inner peripheral surface formed in an annular shape to define a compression space, and configured to communicate with the compression space to suck and provide refrigerant in a lateral direction; a roller rotatably provided in the compression space of the cylinder, and provided with a plurality of vane slots providing a back pressure at one side thereinside at a predetermined interval along an outer peripheral surface; and a plurality of vanes slidably inserted into the vane slots to rotate together with the roller, front end surfaces of which come into contact with an inner periphery of the cylinder by the back pressure to partition the compression space into a plurality of compression chambers, wherein the cylinder further includes a suction passage disposed in a direction crossing the suction port to communicate between the compression space and the suction port, and the refrigerant is allowed to pass through the suction port and the suction passage to flow into the compression space.
