ABSTRACT:
A rotary compressor includes a casing 1 having a curved rotor chamber 2 in which is mounted a rotor 6. The compressor has an outlet valve 10 consisting of two valve units 10a, 10b which are located on inclined support surfaces 12 and outlet passages 11 from the chamber 2 open into the surfaces 12. Each valve unit 10a, 10b consists of a valve seat 15, a valve plate 13 and a limit plate 14, the valve seat 15 having apertures which register with passages 11 and the valve plate 13 having apertures which are staggered from the apertures in the valve seat 15. The support surfaces 12 are positioned close to the chamber 2 so that the length of the passages is small and the "dead volume" between the chamber 2 and the valve plate 13 is reduced.
