Abstract
A rotary compressor includes a cylinder having a slot, an eccentric shaft disposed in the cylinder, a roller formed around the shaft, a vane inserted into the slot and having grooves on its surface, and a sealing material inserted into the grooves. The sealing material prevents leakage and influx of gas through a gap between the cylinder and the vane, improving the efficiency of a rotary compressor.
