Abstract: A side rail is formed into a ring shape having its generally rectangular section that has an outer surface 3 formed with a pair of edge surfaces 5 of small radius, and an intermediate surface 6 of large radius of curvature formed between the edge surfaces 5. When the side rail is in the inclined condition in operation, each edge surface 5 can easily ride on oil film on cylinder 16 and allow the side rail 1 to perform smooth sliding movement on the inner surface of cylinder. The intermediate surface 6 efficiently scrapes lubricating oil on cylinder to form lubricating oil film of necessary and minimum thickness between an inner surface 17 of cylinder 16 and side rail 1. Also, the larger radius of curvature for forming the intermediate surface 6 provides a larger contact area to the inner surface 17 of cylinder 16 to improve wear resistance.

Each arm 7 is provided with a lug 8 to resiliently urge the side rail 5 in radial and outward direction.

Abstract: In a shoe 5 for a swash plate compressor, the conical tapered surface 13 is formed between the spherical surface 10 and the rounded edge 14 to converge toward the spherical surface 10 inside an imaginary spherical surface 15 including the spherical surface 10. The conical tapered surface 13 forms a relatively large arcuate gap 23 between the hemispherical concavity 7 and the conical tapered surface 13. The arcuate gap 23 serves to reserve necessary amount of lubricant oil which may be supplied to sliding portions between the spherical surface 10 of the convex surface 11 and hemispherical concavity 7 of the piston 2. In addition, upon manufacture of the shoe 5, it can easily be removed from a metallic mold 52 due to existence of the arcuate gap 23 which prevents tight fit of the shoe 5 in the mold 52.

Abstract: A pipe coupling is provided having a pair of arcuate housings each provided with a crescent groove and a crescent protrusion formed on an abutting end surface of the arcuate housings in the positions which is symmetrical to each other around a vertical axis and is offset from a transverse central axis. When the arcuate housings are tightened by bolts and nuts, the crescent protrusion is inserted into the crescent groove, thereby causing skewed movement of the arcuate housings around the vertical central axis of the pipe coupling in adverse directions to the predetermined angular positions. Thus, upon completion of tightening by the bolts, excessive tightening by the bolt is prevented due to mutual contact of the abutting end surfaces of the arcuate housings.
