DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a fluid machine which consists of a fluid storage tank provided with an inlet and at least with one outlet nozzle.
2. Background Art
From the Author's Certificate No. 941 665 of the former USSR there is known a hydraulic motor which consists of a rectifying channel, in which a narrowing outlet is made. In the axis of the narrowing outlet there is mounted a spherical rotor on a shaft. The rotor is connected to a starting motor.
At putting into operation, first the shaft is made turning and in this way the spherical rotor as well. The fluid stream which, in the narrowing outlet, flows round the sphere, is made rotating in this way. The rotating fluid stream keeps then the spherical rotor in rotation due to the friction between the fluid and the surface of the spherical rotor. It is necessary to stress that the spherical rotor is not rolling over walls of the narrowing outlet in any regime.
A drawback of said embodiment resides in the fact that the hydraulic motor cannot be put into operation without an auxiliary starting motor.
From another Author's Certificate No. 1701971 of the former USSR there is known an analogous hydraulic motor, where the starting motor is replaced with spiral blades mounted in the narrowing outlet.
As to said embodiment there is also not supposed that the rotor is to roll over the wall of the narrowing outlet.
In the practice there was shown that the flowing round the described type of the rotor causes unnecessary losses. That was why a more suitable embodiment of a fluid machine of a higher efficiency was in search.
SUMMARY OF THE INVENTION
The mentioned aim was achieved by means of a fluid machine comprising of a fluid tank provided with an inlet and at least with one outlet nozzle according to this invention, the principle of which resides in the fact that in the flow area of the outlet nozzle there is mounted, on the holding device, at least one rolling rotor represented by a body of a rotary shape.
The rolling fluid machine according to the invention makes it possible to utilise efficiently the power of the streaming fluid which may be represented not only by a liquid, but also by gas and by mixtures of liquids and gases. A higher efficiency may be achieved especially by decreasing the resistance which arises when the rotor rolls in a fluid. The machine can work even with fluids which are very polluted with mechanical particles. Moreover an eventual exchange of worn parts is very easy.
To increase the efficiency, it is advantageous, if the rotor is separated by means of a plane of the largest diameter into two parts of different capacities, the first part of the rotor adjacent to the outlet nozzle is larger than the second rotor part which is reverse with respect to the outlet nozzle.
According to an advantageous embodiment, the capacity of the second part of the rotor may equal zero and at least a part of the surface of the first part of the rotor may be of a spherical shape.
According to another advantageous embodiment, the whole rotor may be of a spherical shape.
For a appropriate utilisation of the streaming medium, it is advantageous, if the holding device consists of an area of bearing, arranged in the outlet nozzle behind the rotor, or if the holding device consists of a shaft pivoted in a frame and holding the rotor in the axis of the outlet nozzle, and the shaft is flexible at least in a definite section.
According to another advantageous embodiment, the holding device consists of a crankshaft pivoted in a frame and holding the rotor outside the axis of the outlet nozzle.
For an easy transfer of gained power, it is advantageous, if the rotor is provided with magnets, opposite which, in the outlet nozzle, there are mounted magnetic coils, or vice versa, the rotor is provided with magnetic coils, opposite which, in the outlet nozzle, there are mounted magnets, eventually the rotor is represented by a upstream tubular-bulb type turbine with embodying generator.
