Abstract

A compressor for a refrigeration unit having a stator, a rotor orbiting in engagement with the stator to cyclically open, fill with refrigerant gas from at least one inlet port, compress and discharge compressed refrigerant gas through at least one discharge port, a rotary drive for orbiting the rotor, a driven element of a magnetic coupling in driving connection with the rotary drive, a casing sealed save for the ports and enclosing all of the foregoing components, a driving element of the magnetic coupling outside of the casing in close proximity to the driven element, and a motor to rotate the driving element. Preferably the rotor is a multilobed rotor orbiting within a trochoidal chamber defined by the stator. Most preferably, a three lobed rotor is journalled on an eccentr ic carried by a shaft of the rotary drive and has a ring gear driven by a gear of the rotary drive having the same eccentricity as the eccentric and rotated in synchronism therewith, the gear ratio of the ring gear to the eccentric being three to one.
