POWER REDUCING STRUCTURE IN PISTON TYPE COMPRESSOR

摘要

PURPOSE:To restrain power loss by interposing a rolling body between a shoe and swash plate on the side receiving a compression reaction through a piston. CONSTITUTION:The surface of a swash plate 15 at the side receiving a compression reaction through a single headed piston 22 moves relatively to a shoe 23B through a thrust bearing 20. A roller 20c rolls relative to a race 20d at the swash plate 15 side and a race 20b at the shoe 23B side, i.e., the swash plate 15 side race 20a follows the swach plate 15 pivotably and the shoe 23B side race 20b hardly follows the swash plate 15. Thus, the resistance accompanying the relative shift between the swash plate 15 and shoe 23B provides only rolling resistance of the roller 20c which is far smaller than the slide resistance when the swash plate 15 contects directly the shoe 23B. Thus, power loss is reduced and compression efficiency is improved.
