摘要： A scroll compressor having a scroll wall arrangement with a fixed scroll having fixed scroll walls and an orbiting scroll having orbiting scroll wall, an inlet at a radially outer portion and an outlet at a radially central portion, a first flow path defined by the orbiting and fixed scroll walls and extending from the inlet to the outlet, gas entering through inlet at a pressure and exhausting through outlet at a second pressure higher than the first pressure. Scroll wall arrangement having a second inlet through which gas enters at a third pressure and follows a second fluid path where it is exhausted through the outlet at the second pressure to form two flow paths having respective inlets. The third pressure at which gas enters through inlet is different from the first pressure, and lower than the second pressure.

摘要： A method of assembling a scroll pump comprises the following steps carried out sequentially; the step of mounting a first bearing means (20) and drive shaft (14) for rotation relative to a housing (12): the step of fastening a first flange portion (48) of a bellows arrangement (34) relative to the housing (12); the step of fastening an orbiting scroll (26) to a second flange portion (56) of the bellows arrangement (34); and the step of fixing a second scroll (28) relative to the housing (12) for co-operation with the orbiting scroll (26). The second flange portion (56) is fastened to the orbiting scroll (26) with fasteners (60) which extend through a through-bore (61) in the orbiting scroll and engage with the second flange portion.
摘要翻译：一种组装涡旋泵的方法包括顺序执行的以下步骤：安装相对于壳体（12）旋转的第一轴承装置（20）和驱动轴（14）的步骤：将波纹管装置（34）的第一凸缘部分（48）相对于壳体（ 12）; 将旋转涡旋件（26）紧固到波纹管装置（34）的第二凸缘部分（56）的步骤; 以及相对于壳体（12）固定第二涡旋件（28）以与动涡旋盘（26）协作的步骤。第二凸缘部分56用紧固件（60）紧固到绕动涡旋件（26），紧固件（60）延伸穿过绕动涡盘中的通孔（61）并与第二凸缘部分接合。

摘要： A vacuum pump of the scroll-type has a housing, a first fixed scroll member having an end plate and an involute spiral wrap attached thereto and a second orbital scroll member having an end plate and an involute spiral wrap attached thereto. The scroll members are arranged in the housing such that their respective wraps intermesh so that on orbital movement of the second scroll member relative to the first scroll member a volume of gas will be trapped and urged from one end of the wraps to the other end. A shaft for driving the second scroll member and wherein a member is provided which is adapted to separate the vacuum space in the housing from the shaft and also to prevent the second scroll member from rotating the said member being made from a polymer material.
摘要翻译：涡旋式真空泵具有壳体，具有端板和附接到其上的渐开线螺旋状涡卷的第一固定涡旋构件和具有附接到其上的端板和渐开线螺旋状涡卷的第二轨道涡旋构件。涡旋构件布置在壳体中，使得它们各自的缠绕相互啮合，使得在第二涡旋构件相对于第一涡旋构件的轨道运动时，一定体积的气体将被捕获并且被迫从涡卷的一端向另一端施力。一种用于驱动第二涡旋构件的轴，其中设置有一个构件，该构件适于将壳体中的真空空间与轴分离，并且还防止第二涡旋构件使由所述高分子材料制成的构件旋转。
