Abstract
A rotary compressor comprising a cylindrical chamber, a vane slidably mounted in the peripheral cylinder wall and a torsion spring to bias the vane into contact with an eccentrically mounted roller. The spring includes an elongated central portion and a pair of arms extending from the central portion in parallel planes. The arms are curved or radiused in opposite directions. The central portion is connected to the outer edge of the vane while the ends of the arms are connected to opposite side of the cylinder so that the arms exert a torsional force on the central portion.
