ABSTRACT:
A prime mover or pump comprising of a first stationary plate and a second plate arranged parallel to the stationary plate and spaced therefrom. The second plate is rotatably mounted about its central axis. A plurality of elongated wall elements are disposed between the plates. The wall elements slidably bear on the plates to form a seal therewith such that working chambers are created. Each wall element is articulated at one end point to a further wall element such that the wall elements form a movable grid. The grid is rotatably secured at at least one point to the stationary plate and at at least two points to the rotatable plate such that the working chambers assume their maximum and minimum volumes upon rotation of the rotatably plate.
