Scroll type fluid machine

Abstract

A scroll type fluid machine for improving compression efficiency while preventing contact between wrap sections of opposed scrolls, includes a first scroll member provided with a wrap section of a spiral shape on an end plate, a second scroll member disposed at a position opposed to the first scroll member and provided with a wrap section of a spiral shape on an end plate, cooling fins arranged on a back side surface of the end plate of at least one of the first scroll member and the second scroll member, and projected sections arranged on the wrap section of at least one of the first scroll member and the second scroll member, in which a difference of thicknesses in the radial direction of the wrap section at a distal end and a base end of the projected sections is changed depending on a position in a peripheral direction.

Dependencies are inferred from the claim text.
