Abstract
Official abstract text for this publication.
There is provided a shoe for a compressor with improved seizure resistance. The shoe for the compressor includes: a first sliding face that slides on a piston; a second sliding face that slides on a swash plate; and a recess formed in the second sliding face. In a section along a height direction and scaled up 1000 times in the height direction and 10 times in a radial direction, a connecting portion between the second sliding face and the recess 53 is formed in a rounded shape with a radius R2 larger than 5 mm.
First claim

The invention claimed is: 1. A shoe for a compressor comprising: a first sliding face that slides on a piston; a second sliding face that slides on a swash plate; and a recess formed in the second sliding face, wherein, in a section along a height direction of the shoe and scaled up 1000 times in the height direction and 10 times in a radial direction of the shoe, a connecting portion between the second sliding face and the recess is formed in a rounded shape with a radius of curvature larger than 5 mm, and the radius of curvature of the connecting portion between the second sliding face and the recess is larger than a radius of curvature of a connecting portion between the second sliding face and the first sliding face. 2. The shoe for the compressor according to claim 1 , wherein the second sliding face is formed to bulge from a connecting portion between the second sliding face and the first sliding face toward the connecting portion between the second sliding face and the recess. 3. A shoe for a compressor comprising: a first sliding face that slides on a piston; a second sliding face that slides on a swash plate; and a recess formed in the second sliding face, wherein, in a section along a height direction of the shoe and scaled up 1000 times in the height direction and 10 times in a radial direction of the shoe, a connecting portion between the second sliding face and the first sliding face is formed in a rounded shape with a radius larger than 5 mm, a radius of curvature of the connecting portion between the second sliding face and the recess is larger than a radius of curvature of a connecting portion between the second sliding face and the first sliding face. 4. The shoe for the compressor according to claim 3 , wherein the second sliding face is formed to bulge from the connecting portion between the second sliding face and the first sliding face toward a connecting portion between the second sliding face and the recess.
