Spherical energy converter

An energy converter comprising

• a) a housing which confines a spherical working chamber and in which two inlet openings and two outlet openings for a pressurized liquid or gaseous medium are arranged;
• b) a shaft and a hollow shaft receiving the latter, which are mounted rotatably in the housing, wherein each of an axis of rotation of the shaft and an axis of rotation of the hollow shaft coincide with a diameter of the working chamber;
• c) two flat rotary pistons which bear sealingly against an inner wall of the housing and have a circular profile, wherein one of the flat rotary pistons is connected torque proof to the shaft and the other flat rotary piston is connected torque proof to the hollow shaft;
• d) two toothed gears which are connected to either the shaft or to the hollow shaft via a first freewheel coupling, the first freewheel coupling preventing rotation of the toothed gears with respect to the shaft or the hollow shaft counter to the working direction of rotation;
• and
• e) an output toothed gear which meshes with the two toothed gears,
• wherein:
• f) in the housing, the two inlet openings are arranged opposite one another and the two outlet openings are arranged opposite one another,
• g) the shaft and the hollow shaft are each supported in the housing via a second freewheel coupling, the second freewheel coupling preventing rotation of the shaft or of the hollow shaft counter to the working direction of rotation, and
• h) the two flat rotary pistons are each assigned stop bolts which come into engagement with the respective other flat rotary piston, and to move the latter across the two inlet openings, at the end of a working cycle.
