SCREW-TYPE POSITIVE-DISPLACEMENT COMPRESSOR

The compressor incorporates a front inlet aperture consisting of two annular sectors (11, 12) each having an opening angle of less than 200 degrees, the two annular sectors being essentially symmetrical relative to the plane of intersection of the rotor chambers and seperated from one another by a c...

Beschreibung
Zusammenfassung:	The compressor incorporates a front inlet aperture consisting of two annular sectors (11, 12) each having an opening angle of less than 200 degrees, the two annular sectors being essentially symmetrical relative to the plane of intersection of the rotor chambers and seperated from one another by a central portion of an end wall of the casing defining the said annular sectors. The outlet opening (16) is formed in a peripheral wall of the casing and has a general V-shape whose convergent edges are parallel, in projection, to the threads of the respective rotors and whose axial height is less than twice the axial distance between two adjacent rotor threads.
