Beschreibung
Zusammenfassung:	A compressor (20) comprises: a housing assembly (22) having a plurality of ports including a suction port (24) and a discharge port (26); a male rotor (30) mounted for rotation about an axis (500); a female rotor (32) enmeshed with the male rotor and mounted in the housing for rotation about an axis (502) for drawing a flow from the suction port, compressing the flow, and discharging the compressed flow through the discharge port. The housing assembly comprises: a motor case (54); and a cover (60) bearing the suction port. The cover comprises a unitary piece forming: a mounting portion (63) mounted to an adjacent end (55) of the motor case, said adjacent end being large enough to pass the motor; and a fitting portion (62) extending to a rim (66) at the suction port and bearing an external groove (200). L'invention concerne un compresseur (20) comprenant : un ensemble logement (22) ayant une pluralité d'orifices comprenant un orifice d'aspiration (24) et un orifice d'évacuation (26) ; un rotor mâle (30) monté pour tourner autour d'un axe (500) ; un rotor femelle (32) engrené avec le rotor mâle et monté dans le logement pour tourner autour d'un axe (502) afin d'attirer un flux depuis l'orifice d'aspiration, comprimer le flux et évacuer le flux comprimé par l'orifice d'évacuation. L'ensemble logement comprend : un carter de moteur (54) ; et un capot (60) portant l'orifice d'aspiration. Le capot comprend une pièce unitaire formant : une partie de montage (63) montée sur une extrémité adjacente (55) du carter de moteur, ladite extrémité adjacente étant suffisamment grande pour passer après le moteur ; et une partie de raccordement (62) s'étendant jusqu'à un rebord (66) au niveau de l'orifice d'aspiration et portant une rainure externe (200).
