Abstract
The present invention provides an improved swash plate type variable capacity fluid machine which is fluid-tight, simple in structure, quiet in operation, and highly durable, yet without increasing its size, weight, and the amount of power loss. The swash plate type variable capacity fluid machine includes: a cone; a disk; an enclosure wall whose inner shpherical surface surrounds the outer circumference of the disk; and a partition plate movably fitted in a groove of the cone. The cone and the disk are arranged to confront each other on an abutment line, thereby defining a plurality of variable capacity compartments. Supplying/discharging holes are provided to communicate with the variable capacity compartments, supplying and discharging a fluid there from. A synchronous mechanism causes the cone and the disk to rotate about their center axis in synchronization.
