Specifically the features relate to (1) the compressor motor; (2) a non-vented motor housing and back or closure; (3) the inlet ring; (4) the bearing system; (5) the rotor and vane positioning and vane weight or mass; (6) the mass of the body within which the rotor and vane rotate; and (7) a shroud which surrounds the body which is solid and non-vented solid and may be formed of a laminated material having a sound dampening core layer.

Sound reduced rotary vane compressor

An improved rotary vane compressor includes an elongated housing having a main part and two ends. An inlet/outlet end plate member positioned at one end of the housing has an inlet port and an outlet port. The end plate member is one of a first type having ports constructed for tube-type connections and to receive a tube type conduit or a second type having an ports constructed for threaded type connections. Intermediate adapter member positioned between the housing and the end plate member, is secured to the housing and adapted to receive an end plate member of either the first type or the second type.
