Modified rotary compressor yielding sinusoidal pressure wave outputs

摘要

A rotary compressor in which a slice is cut back under one rotor flank and a continuous groove is cut in the rotor housing cover adjacent the slice and intersecting it. The two adjacent rotor flanks can be ported to prevent pressure buildup therein. This arrangement permits the volume under the modified rotor flank to be in constant communication with the compressor output and produce a true sinusoidally varying pressure output.
