摘要: A rotary compressor may include a case, a cylinder, a roller, a vane, a main bearing and a sub bearing, and a discharge passage defined in the main bearing or the sub bearing to discharge refrigerant compressed in a compression space. The discharge passage may include at least one discharge hole formed through the main bearing or the sub bearing, and at least one discharge guide groove having a first end that communicates with the at least one discharge hole and a second end that extends from the at least one discharge hole toward a contact point between the cylinder and the roller and is recessed from one surface of the main bearing or the sub bearing forming the compression space. Accordingly, an amount of refrigerant remaining in the compression space even after a discharge stroke may be reduced.

摘要: 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.

摘要: A rotary compressor is provided that may include a cylinder having an inner peripheral surface defined in an annular shape to define a compression space, and provided with a suction port configured to communicate with the compression space and through which refrigerant is suctioned into the compression space; a roller rotatably provided in the compression space of the cylinder, and having a plurality of vane slots that provides a back pressure at one side thereinside and that is provided at a predetermined interval along an outer peripheral surface of the roller; and a plurality of vanes slidably inserted into the plurality of vane slots, respectively, and configured to rotate together with the roller, front end surfaces of which come into contact with the inner peripheral surface of the cylinder due to the back pressure to partition the compression space into a plurality of compression chambers. High-pressure refrigerant may be accommodated between one of the plurality of vanes and the inner peripheral surface of the cylinder.

摘要: A rotary compressor is provided that may include a rotational shaft, first and second bearings configured to support the rotational shaft in a radial direction, a cylinder disposed between the first and second bearings to form a compression space, a rotor disposed in the compression space and coupled to the rotational shaft to compress a refrigerant as the rotor rotates, and at least one vane slidably inserted into the rotor, the at least one vane coming into contact with an inner peripheral surface of the cylinder to separate the compression space into a plurality of regions. The at least one vane may include a pin that extends in an axial direction, and at least one of the first bearing and the second bearing may include a rail groove into which the pin may be inserted.
