Problems solved by technology

[0005] A common drawback of all known rolling or precessing machines / turbines is that they do not deal with the losses caused by the precessing motion of the shaft in the fluid, nor provide an easy and reliable protection of the current generator from water ingress

Embodiment Construction

[0014] according to figure 1 The precessing fluid turbine comprises a fluid reservoir 8 having a fluid inlet opening 3 and a fluid outlet opening 4 . The stator nozzle 1 is arranged in a fluid reservoir 8 between a fluid inlet opening 3 and a fluid outlet opening 4 . Arranged in the stator nozzle 1 is a vaneless rolling rotor 2 with a shaft 9 . The rolling rotor 2 can have any shape of revolution.

[0015] The rolling rotor 2 is mounted on a holding device 6 . The retaining means 6 may consist of any known mechanism which enables the rolling rotor 2 to roll in a convoluted manner along the inner wall of the stator nozzle 1 . exist figure 1 In the embodiment of the present invention, the holding device 6 comprises a rod-shaped support firmly connected to the bottom of the rolling rotor 2 and mounted in a bracket 19 terminating in a ball joint on the opposite side.

[0016] In the fluid reservoir 8, above the rolling rotor 2 there is an air chamber 10 at least partially sub...

Abstract

A precessing fluid turbine comprising a fluid reservoir (8) having an inlet fluid opening (3) and an outlet fluid opening (4). The stator nozzle (1) is arranged in a fluid reservoir (8) between an inlet fluid opening (3) and an outlet fluid opening (4). In the stator nozzle (1) is arranged a bladeless rolling rotor (2) comprising a revolving body with a shaft (9) mounted on a holding device (6) and able to swivel on the inner wall of the stator nozzle (1) scroll. The rolling rotor (2) is interconnected with a current generator (7) by means of a mechanism (5). In the fluid reservoir (8), an air chamber (10) is arranged above the rolling rotor (2), which is open at the bottom end, into which the shaft (9) of the rolling rotor (2) protrudes ( 10). A current generator (7) interconnected with the shaft (9) of the rolling rotor (2) by means of a mechanism (5) is arranged in the air chamber (10).

Description

technical field [0001] The invention relates to a precessing fluid turbine comprising a fluid reservoir having an inlet fluid opening and an outlet fluid opening, in which fluid reservoir is arranged between the inlet fluid opening and the outlet fluid opening A stator nozzle in which is arranged a vaneless rolling rotor comprising a revolving body with a shaft, which is mounted on a retaining device so that the rolling rotor can revolve and roll on the inner wall of the stator nozzle , the rolling rotor is interconnected with the current generator by means of a mechanism. Background technique [0002] Fluid machines are known which have a stator with an inlet fluid opening and an outlet fluid opening, and in which stator a vaneless rolling rotor is mounted on a holding device, the rolling rotor comprising a body having a shape of revolution. The retaining means are adapted to enable the rolling rotor to roll convolutedly on the inner wall of the stator. After being provid...
