SCROLL COMPRESSOR

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.

1. A scroll compressor comprising:
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, wherein the orbiting scroll has an orbiting scroll wall extending axially from an orbiting scroll plate towards the fixed 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, wherein:
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;a first portion of at least one of the first or second seal has a first aspect ratio of an axial length to a radial width and a second portion of the at least one of the first or second seal has a second aspect ratio of the axial length to the radial width; andboth the first aspect ratio and the second aspect ratio are at least 1.25:1.
