More Information
Summary:A scroll pump comprises a housing, a fixed scroll, an orbiting scroll and a rotation-resisting assembly including first and second devices 340, 342. The first device comprises a first body portion 402 and first and second arms 404, 406 extending therefrom. The first arm is coupled to the orbiting scroll and the second arm is coupled to a relatively fixed component of the scroll pump. The first and second arms extend and flex to allow movement of the orbiting scroll relative to the housing in generally orthogonal directions. The second device comprises a second body portion 502 and third and fourth arms 504, 506 extending therefrom. The third arm is coupled to the orbiting scroll and the fourth arm is coupled to the relatively fixed component. The third and fourth arms extend and flex to allow movement of the orbiting scroll relative to the housing in generally orthogonal directions. The first and second arms may each be one of a pair of first and second arms on opposing sides of the first body portion.
