<p>New system of rotary propeller pump for high speeds of revolution and high outputs, characterized in that the propeller is comprised of a single blade (S) on the shaft (1) or on the useful cylinder (6-6'). The linear speed and the flow rate are very high and may actuate the largest alternators and work in closed circuit. The pump may also be used for the propulsion of ships, by substituting the propeller. It may also operate as an air compressor at low, medium and high pressures, as well as a blowing machine.</p> |
