PROBLEM TO BE SOLVED: To promote the miniaturization of a compressor in reducing a connecting part between a swash plate and a piston, insofar as possible by forming a radius of curvature of a spherical surface of a shoe on one side receiving suction force, out of a pair of shoes slidingly contacting with both surfaces of the swash plate, to be smaller than that of a spherical surface of the shoe on the other receiving compressive force. SOLUTION: When the power of a mounted engine is transmitted to a shaft 5, the torque is transmitted to a swash plate 10 by way of a thrust flange 40, linkage 41, and this swash plate 10 is rotated. Since two shoes 60 and 61 relatively rotate on the swash plate 10 by a rotation of this swash plate 10, a piston 7 is made to do its rectilinear reciprocation. At this time, a radius of curvature in a spherical surface of the shoe 61 on one side receiving suction force out of these paired shoes 60 and 61 is made smaller than that of a spherical surface of the shoe 60 on the other receiving compressive force, and then both centers of curvature of spherical surfaces of both these shoes 60 and 61 are accorded with each other. With this, in time of the swash plate 10 being tilted, such a possibility that a clearance might be produced in space between the swash plate 10 and the paired shoes 60, 61 is prevented from occurring and, what is more, the occurrence of noise is checked. |
