Abstract
Disclosed are a rotary compressor and a refrigeration cycle device having the same. The rotary compressor and the refrigeration cycle device having the same may include a casing, a main bearing, a sub bearing, a cylinder, a roller, a vane, and an injection passage, and the injection passage may be disposed in at least one selected from the main bearing, the sub bearing, and the cylinder to communicate with a corresponding compression chamber after a compression start angle of the corresponding compression chamber. Thus, a maximum injection section may be secured, while a refrigerant being injected may be suppressed from being leaked toward a suction port.
