Abstract
Provided is a scroll compressor that can prevent liquid from being accumulated, the scroll compressor including: a fixed scroll; an orbiting scroll; and a rotation shaft that extends in the horizontal direction and causes the orbiting scroll to orbit relative to the fixed scroll. Liquid is injected into a working chamber. An enclosing point of a working chamber formed near the outer end of a fixed wrap of the fixed scroll is positioned below a center of the rotation shaft and at the lowest point of the contour of the working chamber having shifted to the lowest position. The fixed scroll has an inclined wall surface that is positioned below the center of the rotation shaft, is made to face upward, and extends from the dust wrap to the outer end of the fixed wrap. The inclined wall surface is formed so as to be sloped down gradually from the dust wrap toward the outer end of the fixed wrap.
