Abstract

A fluid jet system for pumps or turbines etc, especially for hydro electric turbines, has a rotor (1) with its vertical drive shaft (2) driven by a motor (4) above, with centrifugal channels (8) which discharge liquid outwards into a ring shaped channel (12) and hence into tangential receiving nozzles (14) so that liquid is circulated through them from a toric reservoir (19) with water (20) in its lower part and air (25) above, pumped from a reservoir (23) below. Nozzles (28) around the ring shaped channel (12) spray a water and air mixture into the flared ends of the receiving nozzles (14) and the liquid is forced through them with a pulsating action. These flared ends are shaped as a ring of rectangular openings, and the discharge opening (9) are also rectangular openings, but of more elongated shape.
