An apparatus for transporting gases, liquids and the like by means of a conical screw type propeller 10 which sucks gases or liquids in and passes them along. The propeller consists of at least two guide panels 1, 2 of helicoidal configuration which define apertures 3 in the area of the tips. The propeller may be mounted on a baffle plate 11.

A fluid transport apparatus, comprising: (a) a solid baffle plate (11), and (b) a generally conical propeller (10) rotatably mounted closely proximate the baffle plate and axially perpendicular thereto, an apex portion of the propeller being oriented in a direction facing away from the baffle plate, and the propeller comprising: (1) at least two helicoidal blades (1, 2) equally spaced around a circumference of the propeller and spiralling inwardly towards the apex portion with leading edges of the blades disposed side by side at said apex portion and on opposite sides of the propeller axis, and (2) at least two helical guide panels (4) interconnecting the blades such that the leading edges of the blades are disposed inwardly of the guide panels at the apex portion and trailing edges of the blades are disposed outwardly of the guide panels at an open bottom, base portion of the propeller, the blades and panels thus defining a convolute propeller configuration with a pair of oppositely oriented entry apertures (3) at the apex portion such that fluid is drawn in through the apertures, screw pumped downwardly and outwardly within the propeller toward the base portion, and expelled outwardly therefrom against the baffle plate, the expelled fluid being deflected outwardly by the baffle plate to flow across a surface thereof and transportingly entrain additional fluid surrounding the propeller.
