Abstract
A compressor, more particularly, a scroll compressor provides structures that may enhance centrifugal stiffness at a contact point between a fixed scroll and an orbiting scroll. The compressor may include an orbiting scroll having an orbiting scroll wrap wound around a radial-direction inner area from a radial-direction outer area; and a fixed scroll having a fixed scroll wrap wound around the radial-direction inner area from the radial-direction outer area. A surfacing part may be configured to narrow a distance between the orbiting scroll wrap and the fixed scroll wrap may be formed in a predetermined section of the orbiting scroll or fixed scroll wrap.
Claims14
A compressor comprising:
- an orbiting scroll having an orbiting scroll wrap;
- a fixed scroll having a fixed scroll wrap;
- and
- a protrusion that is disposed at the orbiting scroll wrap or the fixed scroll wrap and that reduces a distance between the orbiting scroll wrap and the fixed scroll wrap,
- wherein the orbiting scroll and the fixed scroll are configured to, based on the orbiting scroll orbiting with respect to the fixed scroll, define a plurality of contact points between the orbiting scroll wrap and the fixed scroll wrap, and
- wherein the protrusion is disposed at an innermost contact point of the plurality of the contact points that is located at an innermost area in the radial direction, and
- wherein the protrusion has a thickness that is smaller than a thickness of a lubricant film that is disposed at the contact points between the orbiting scroll wrap and the fixed scroll wrap.
A compressor comprising:
- an orbiting scroll having an orbiting scroll wrap;
- a fixed scroll having a fixed scroll wrap;
- and
- a protrusion that is disposed at the orbiting scroll wrap or the fixed scroll wrap and that reduces a distance between the orbiting scroll wrap and the fixed scroll wrap,
- wherein the orbiting scroll wrap and the fixed scroll wrap have thicknesses that at least partially vary, and
- wherein the distance between the orbiting scroll wrap and the fixed scroll warp is constant except for an area including the protrusion.
