Abstract
A rotary compressor in which a slice is cut back under one rotor flank and 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.
Claims6
In a rotary compressor device in which substantially trochoidal curves form the inner surface of the working chambers and the configuration of the internally placed rotary piston of said device and wherein side surfaces close the device to complete the working chambers, the improvement comprising:
- a volume formed along a flank of said rotary piston in communication with the compression volume under said flank and adjacent a side surface;
- passageway means associated with said side surface for constantly communicating with said volume as said rotary piston revolves;
- and
- porting means communicating with said passageway means for providing an outlet for sinusoidally varying pressure generated by said device.
