A spherical piston machine comprises a chamber whose wall is at least partly spherical. A spherical piston, mounted within this chamber, comprises two elements, the chamber and piston delimiting a free space of variable shape. At least one of the elements of the piston is angularly fixed to a control axle, forming an angle with the longitudinal axis of the machine and extending in a direction passing through the center of the spherical chamber. The two elements of the spherical piston are articulated in a zone extending perpendicular to each control axle. Means are provided for rotatably driving about its own axis at least one of the control axles, as well as for rotatably driving each control axle about the longitudinal axis of the machine.
