Abstract
An embodiment may have two rotary discs including a second disc (a cap) and a first disc; and a rotary 'cam' (having ports) placed in the central hole of the first disc. A cap is half the diameter of the first disc. Both face each other and maintain contour complementarity during both of two modes of operation The cap seals the cavity underneath, and without jeopardizing the sealing, permits entry and exit of the radial ridges and furrows of the first disc into it. The ridges sweep the floor (under surface) of the cap and divide the cavity into variable volume compartments that suck and expel fluid simultaneously through the 'cam'. The machine is designed to work as rotary pump, compressor, turbine or internal combustion engine.
