Abstract
A rotary compressor is provided that may include a cylinder having an inner circumferential surface with an annular shape to form a compression space; a roller having a plurality of vane slots disposed at predetermined intervals along an outer circumferential surface thereof, and rotatably inserted into the compression space of the cylinder; and a plurality of vanes slidably inserted into the respective vane slots to rotate together with the roller and by which the compression space is divided into a plurality of compression chambers. At least one of the vane slots is unequally spaced in a circumferential direction. Accordingly, periodicity of noise may be reduced to thereby increase the effect of noise reduction of the compressor.
Claims20
A rotary compressor, comprising:
- a cylinder having an inner circumferential surface with an annular shape to form a compression space;
- a roller rotatably provided in the compression space of the cylinder and having a plurality of vane slots disposed at predetermined intervals along an outer circumferential surface thereof;
- and
- a plurality of vanes slidably inserted into the respective vane slots to rotate with the roller and by which the compression space is divided into a plurality of compression chambers, wherein at least one of the plurality of vane slots is unequally spaced in a circumferential direction.
A rotary compressor, comprising:
- a cylinder having an inner circumferential surface with an annular shape to form a compression space;
- a roller having at least one vane slot formed on an outer circumferential surface thereof and rotatably inserted into the compression space of the cylinder;
- and
- at least one vane slidably inserted into the at least one vane slot to rotate together with the roller and drawn out from the at least one vane slot to divide the compression space into a plurality of compression chambers, wherein the vane includes a vane front end portion in contact with the inner circumferential surface of the cylinder, and a vane rear end portion disposed at an end surface opposite to the vane front end portion to receive pressure, and wherein a chamfer portion for pressing the at least one vane toward an inner surface of the at least one vane slot is formed on an edge, of edges of the vane rear end portion in a circumferential direction, disposed in a rotational direction of the roller.
A rotary compressor, comprising:
- a cylinder having an inner circumferential surface with an annular shape to form a compression space;
- a roller rotatably provided in the compression space of the cylinder and having a plurality of vane slots disposed at predetermined intervals along an outer circumferential surface thereof;
- and
- a plurality of vanes slidably inserted into the respective vane slots to rotate with the roller and by which the compression space is divided into a plurality of compression chambers, wherein the plurality of vanes pass through a specific crank angle at irregular time intervals.
