Abstract

The rotary machine has a shaft on which is mounted an eccentric carrier, radial piston-cylinder units being disposed around the eccentric. Axial inlet and outlet passages communicating with respective ports in the eccentric. The ports are circumferentially spaced around the eccentric a distributor ring being positioned between the eccentric and the piston-cylinder units. A circular control track cooperates with a control member connected to the machine casing. The control member comprises a ball positioned between two toxic sockets whose concavities are turned towards each other, one socket being provided on the distributor ring and the other on the casing.
