Abstract
A rotary compressor is provided that may include at least one vane that is slidably inserted into at least one vane slot provided in a roller or a cylinder so as to separate a compression space into a plurality of compression chambers. The at least one vane has an at least one oil supply groove formed in at least one of axial side surfaces, respectively, facing a main bearing and a sub bearing. The at least one oil supply groove may be longer in a longitudinal direction of the at least one vane than in a widthwise direction of the at least one vane. With this structure, it is possible to suppress friction loss and wear on a friction surface by supplying oil to the friction surface in contact with the at least one vane.
