SCROLL COMPRESSOR DISCHARGE PORT

摘要

A scroll compressor is provided with a recess to increase the flow area through which compression chambers communicate with a discharge port. The scroll compressor is of the sort having a wrap with a swing radius that is always equal to or greater than zero. That is, this invention does not apply to the type of scroll compressor wherein a swing radius will cross zero as the wrap is generated. Stated another way, a forward ledge of the scroll compressor can be defined spaced towards a tip of the scroll wrap relative to a rear ledge. The present invention provides a recess in the type of scroll wrap wherein the forward ledge has a thickness that is at least equal to or greater than the thickness of the scroll wrap at the rear ledge. A supplemental recess may be provided in the non-orbiting scroll wrap. The recess in the orbiting scroll may be stepped to have different height portions.
