A REVOLVING VANE COMPRESSOR AND METHOD OF OPERATING THE SAME

摘要

A revolving vane compressor and a method of operating a revolving vane compressor are disclosed. The compressor includes a tubular sleeve having a first rotational axis; a rotor disposed within the sleeve, the rotor having a second rotational axis offset from the first rotational axis such that a channel is formed between the sleeve and the rotor; a primary vane configured to mechanically connect the sleeve and the rotor such that the sleeve is operable to drive the rotor, and vice versa; at least one secondary vane, the primary vane and the at least one secondary vane partitioning the channel into a plurality of chambers; a plurality of suction ports, each associated with one of the plurality of chambers; and a plurality of discharge ports, each associated with one of the plurality of chambers. Each of the suction ports is operable to draw a first predetermined volume of a compressible fluid into its associated one of the plurality of chambers, each of the primary and secondary vanes is operable to compress the fluid in its associated one of the plurality of chambers to a second predetermined volume, and each of the discharge ports is operable to discharge the compressed fluid from its associated one of the plurality of chambers, thereby producing a plurality of discharges per each complete revolution of the rotor and sleeve. The at least one secondary vane extends outwardly from the rotor relative to the second rotational axis, a first end of the at least one secondary vane being in sliding engagement with the rotor, and a second end of the at least one secondary vane abutting an inner wall of the sleeve.
