Rotary compressor with unequally spaced vane slots

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, wherein the outer circumferential surface of the roller has a circular shape with a constant diameter in the circumferential direction, and wherein angles between virtual lines respectively passing through entry points of the plurality of vane slots in contact with the outer circumferential surface of the roller and a rotational center of the roller satisfy the following formula:
• θi=θi+Δθ×Sin(m×θi), where θi denotes an equal interval angle, θi′ denotes a rearrangement angle of the vane slots, Δθ denotes a maximum variable angle, and m denotes the order of the vanes.
