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); afemale 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 externalgroove (200). 种压缩机(20)包括：具有多个端口的外壳组件(22)，所述多个端口包括抽吸端口(24)和排放端口(26)；阳转子(30)，其被安装成围绕轴线(500)旋转；阴转子(32)，其与所述阳转子啮合并安装在所述外壳中，用于围绕轴线(502)旋转，以用于从所述抽吸端口汲取流、压缩所述流并通过所述排放端口排放所述压缩的流。所述外壳组件包括：马达壳体(54)；以及承载所述抽吸端口的盖(60)。所述盖包括整体件，所述整体件形成：安装部分
