    Abstract: A rotary compressor: a casing; a plurality of bearings provided in an internal space of the casing; at least one cylinder that is provided between the bearings to form a compression space and has a vane slot; a rolling piston that is accommodated in the compression space to perform an orbiting movement; at least one vane that is slidably inserted into the vane slot of the cylinder and, along with the rolling piston, separates the compression space into a suction chamber and a discharge chamber; a discharge cover that comes with a noise reducing space to accommodate refrigerant discharged from the compression space; and a bypass flow path that allows the noise reducing space of the discharge cover to be connected between a sidewall of the vane slot and a side of the vane facing the sidewall, so that the refrigerant discharged to the noise reducing space is supplied to the side of the vane. Accordingly, the refrigerant discharged via the discharge port is supplied to the side of the vane through the bypass flow path before released to the casing, thereby applying uniform force to opposite ends of the vane.

    Abstract: Provided is a rotary compressor. The rotary compressor includes a rotation preventing key between a roller and a rotating shaft: The roller is a separable-type roller assembled into the rotating shaft. The rotation preventing unit may constrain rotation of the roller and allow axial movement of the roller with respect to the rotating shaft. Thus, axial movement of the roller along the rotating shaft may be suppressed, and thus, friction loss and abrasion between the roller and a main bearing or between the roller or a sub bearing may be suppressed.

    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.
