Abstract

Device for converting kinetic energy contained in a fluid, into mechanical energy, coupled to an either gaseous or liquid fluid mass outlet secondary conduit, constituted by a fixed main conduit receptor of said fluid mass and a movable conduit coaxially attached to an axial flow rotor and associated to an outer supporting frame, including this assembly a flange abutting with said fixed conduit; both conduits are assembled by a fitting device comprising a lid, sealing washers, bearings and retaining ring acting on spacing sleeves and a locking nut; the movable conduit attached to the rotor rotates along its axis and coaxial to said fixed conduit without a major axial displacement; within said rotor it is lodged a hub and a deflector capable of directing the fluid's flow toward passages within the hollow blades and their corresponding exits at the end of each blade, constituting each one of said exit outlets an ejector means for the fluid, thereby achieving the rotational movement of the rotor on its axis; attached to said rotor there is a driven shaft with coupling means to the shaft of the driven means, such as an electrical generator.

A device for converting kinetic energy contained in a fluid, into mechanical energy, coupled to an either gaseous or liquid fluid mass (Mf) outlet secondary conduit (1), characterized by being constituted by a fixed main conduit (3) receptor of said fluid mass and a movable conduit (4) coaxially fitted to said fixed conduit (3);

this movable conduit (4) has attached to its free end an axial flow rotor (12) and associated to an outer supporting frame (17), including this assembly a flange (2) abutting with said fixed conduit (3), both conduits (3, 4) are assembled by a fitting device comprising a lid (5), sealing washers (6), bearings (7) and retaining ring (8) acting on spacing sleeves (9,10) and a locking nut (11);
the movable conduit (4) attached to the rotor rotates along its axis and coaxial to said fixed conduit (3) without a major axial displacement;
within said rotor (12) is lodged a hub (13) and a deflector (14) capable of directing the fluid's flow toward passages within the hollow blades (15) and their corresponding exits at the end of each blade, constituting each one of said exit outlets an ejector means (16) for the fluid (S1), thereby achieving the rotational movement of the rotor on its axis;
attached to said rotor there is a driven shaft (20) with coupling means (21) to the shaft (22) of an electrical generator (23), said deflector (14) has a curved ascending profile capable of directing the fluid's flow towards the inner passage of the rotor's hollow blades, said supporting frame (17) is totally or partially absent and the driven shaft is profiled at its free end to receive a pulley wheel (24) therein fixed by means of a cotter (25) and retaining nuts (26).
