摘要： PROBLEM TO BE SOLVED: To provide a compressor of improved sliding properties during operation. SOLUTION: An annular protrusion 50 is provided on a surface of a swash plate 28. A slit 51 is provided at a part of the protrusion 50. A segment B connecting a center and a top dead center position of the swash plate 28 crosses the slit 51. An air supply passage 41 providing communication between the delivery chamber 39 and a crank chamber 20 jets refrigerant from the protrusion 50 of the swash plate 28 toward a radial direction inside region. Lubricating oil supplied from the air supply passage 41 and adhering on a center part of the swash plate 28 moves to an outer circumference side by receiving centrifugal force due to rotation of the swash plate 28. At that time, flow of the lubricating oil is dammed by the protrusion 50 and moves to the swash plate outer circumference side through the slit 51 exclusively connected to an outer circumference side. Consequently, sliding properties are improved since most of lubricating oil flows toward the top dead center region during operation. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a variable displacement compressor in which lubricating oil having flowed out of a control pressure chamber holding a cam body can be easily returned to the control pressure chamber. SOLUTION: A sleeve 48 is slidably fit on the periphery of a rotation shaft 18 between a rotation support 21 and a swash plate 22. At the time when the angle of inclination of the swash plate 22 is decreasing, the sleeve 48 follows the inclination of the swash plate 22 by the spring force of a compression spring 49. At the time when the angle of inclination of the swash plate 22 is increasing, the sleeve 48 is pushed to the rotation support 21 against the spring force of the compression spring 49. An opening 482 is formed in the sleeve 48. In the rotation shaft 18, a 1st conduction path 46 , and a 2nd conduction path 47 are formed. The sleeve 48 can open/close the 2nd conduction path 47. When the opening 482 has communicated with the 2nd conduction path 47, an in-shaft path 44 communicates with the control-pressure chamber 121 through the 2nd conduction path 47 and the opening 482.
