A variable capacity rotary compressor has a simplified structure to reduce
manufacturing costs and assembling time thereof and is capable of easily
and conveniently performing a capacity-changing operation. The variable
capacity rotary compressor includes first and second compression chambers
having different capacities, a rotary shaft disposed through the first
and second compression chambers, first and second eccentric cams mounted
at the rotary shaft in the first and second compression chambers,
respectively, first and second eccentric bushes rotatably mounted at
outer surfaces of the first and second eccentric cams, respectively, a
connection part connected between the first and second eccentric bushes,
the connection part having a latching groove extending in a rotating
direction of the rotary shaft, a latching pin protruding from the rotary
shaft such that the latching pin is disposed in the latching groove, and
holding grooves depressed by a predetermined depth at opposite ends of
the latching groove in a longitudinal direction of the rotary shaft to
hold the latching pin therein.
