摘要： A vacuum pump (10) includes a pump casing (56) having an inlet port (54a), an outlet port (54b), and pump chambers (50a-50f) defined therein, rotational shafts 60 having opposite ends rotatably supported by bearings (84a, 84b) on the pump casing (56) and extending longitudinally in the pump casing (56), and rotors (62a-62f) housed in the pump chambers (50a-50f) and coupled to the rotational shafts (60) for rotation in unison with the rotational shafts (60). The pump casing (56) has an atmosphere-vented compartment (52) defined therein which is held in fluid communication with the outlet port (54b) of the pump casing (56) and vented to the atmosphere.

摘要： A vacuum pump (10) has a pump casing (54) including pump chambers (50a-50f) held in fluid communication with each other and arrayed in a longitudinal direction thereof, an inlet port (52a) and an outlet port (52b), a rotational shaft (58) rotatably supported at opposite ends thereof and extending in the longitudinal direction of the pump casing (54), and rotors (60a-60f) housed in the pump chambers (50a-50f) and coupled to the rotational shaft (58). The pump casing (54) includes a first thermally conductive member (72) extending parallel to the rotational shafts (58) substantially the full length of the pump casing (54) in the longitudinal direction thereof, and a second thermally conductive member (74) positioned near an end of the first thermally conductive member (72) at the outlet port (52b) and extending in a transverse direction of the pump casing (54).
摘要翻译：真空泵（10）具有泵壳（54），泵壳（54）包括彼此保持流体连通且沿其长度方向排列的泵室（50a-50f），入口（52a）和出口（52b）旋转轴（58），其可旋转地支撑在其相对端并在泵壳体（54）的纵向方向上延伸;以及转子（60a-60f），容纳在泵室（50a-50f）中并联接到旋转轴 58）。所述泵壳体（54）包括在所述泵壳体（54）的纵向方向上大致整个长度的平行于所述旋转轴（58）延伸的第一导热构件（72）和第二导热构件（74）在所述出口（52b）处位于所述第一导热构件（72）的端部附近并沿所述泵壳体（54）的横向方向延伸。
