Abstract
Improvements introduced in elliptical rotary piston pumps, characterized in that it includes an element that allows the oscillating obturator, automatically controlled by the piston itself along its rotation, without any intermediate shaft, to constantly ensure the tightness between the suction and the discharge the pump, thanks to a permanent contact between the lips of the aforesaid obturator and the surface of the aforementioned elliptical piston, independently of the fact that the elements constituting the aforementioned obturator are themselves rigid.
