摘要： A scroll compressor 10 may include an orbiting scroll having an orbiting scroll wall extending axially from an orbiting scroll plate towards a fixed scroll; a fixed scroll having a fixed scroll wall extending axially from a fixed scroll plate towards the orbiting scroll; and an axially extending drive shaft having an eccentric shaft portion so that rotation of the eccentric shaft portion imparts an orbiting motion to the orbiting scroll relative to the fixed scroll. An axial end portion of the orbiting scroll wall has a first seal for sealing between the orbiting scroll wall and the fixed scroll plate, and an axial end portion of the fixed scroll wall has a second seal for sealing between the fixed scroll wall and the orbiting scroll plate; and the first seal or the second seal has an aspect ratio of axial length to radial width which is 1.25:1 or greater.

摘要： A scroll pump tip seal to be fitted to a tip face of a scroll wall of a first scroll of a scroll pump to seal between the tip face and a base plate of a second scroll of the scroll pump has a first end, a second end and a plurality of flexure formations. The flexure formations are at least partial discontinuities in the tip seal disposed at spaced apart intervals between the first and second ends of the tip to facilitate lateral flexure of the tip seal.
