| description | A scroll pump includes a frame, a stationary plate scroll, an orbiting plate scroll, a non-energized type of tip seal or seals, an eccentric drive mechanism assembled to and supported by the frame and to which the orbiting plate scroll is assembled so as to be drivable by the eccentric drive mechanism in an orbit about a longitudinal axis of the pump, and an axial compliance system including a flexure. The flexure is interposed between a bearing of the eccentric drive mechanism and a flexure-locating surface of the eccentric drive mechanism. The flexure allows the orbiting plate scroll to move away from the stationary plate scroll in the case of an assembly process which would otherwise result in the tip seal(s) being too forcefully engaged with the plate of the opposing plate scroll. |
