The invention relates to turbidostat.

The prior art turbine having a casing that provides the centripetal movement of the working fluid (liquid or gas)driving shaft (see, for example, US 4530640, IPC 7 F 02 B 39/00, 23.07.1985 or US 4835960, IPC 7 F 02 C 3/16, 06.06.1989).

The prior art turbomachine, comprising a housing with a spiral guiding device and centripetal turbine (A.S. No. 165039, F 02 C 3/09, 14.10.64).

From the patent RU 2041384 C1, IPC 7 F 03 B 3/02, 09.08.1995 famous labyrinth-vortex hydraulic machines with axial turbine, comprising a housing with inlet and outlet nozzles and inside it fixed and fixed on the shaft of the movable disks with grooves and projections on the surfaces forming the working channels. Inlet connection is located on the periphery and is made tangential and the outlet is located centrally and executed axial. The rotary element in a given machine are mounted on the shaft drives.

The disadvantages of all the above devices are the complexity of their design, high cost of production.

The objective of the invention is to simplify, cheapen the construction, noise reduction while maintaining performance of the turbomachine.

To solve this problem in the turbine containing cylindrical body located at its periphery tangential EAP is SKN outlet for the working fluid and located in the center of the axial discharge port, also mounted on the shaft of the rotor, according to the invention the rotor is constructed in the form of closed one end of the glass, the tangential inlet nozzle provided with an axial spiral guiding element with the possibility of tangential supply of the working fluid on the wall of the Cup near its open end, and an axial discharge port placed its inlet in the cavity of the Cup.

In addition, the inlet pipe may have a rectangular cross-section, and an exhaust - round.

The operation of the turbine based on the formation of torque by adding the vector momentum of the working fluid (gas, liquid) and the vector of reaction forces bearing on the inner surface of the glass of the turbine (rotor). Torque of the turbine equal to a fraction, the numerator of which is the product of the coefficient of proportionality, the second mass of the working fluid (gas, liquid), the square of the velocity of the working fluid relative to the inner surface of the turbine rotor and the denominator of the inner radius of the glass (turbine rotor).

The rotation of the rotor occurs due to the formation of radial vortex spin centripetal flow in the near-wall region of the glass (of the rotor). The working body, getting into the working cavity of the glass, ensures the transfer of energy. Converts the kinetic energy of the swirling flow into mechanical energy of rotation of the Ala of the turbine. Regulation of the degree of swirl flow can be changed by changing the flow rate of the working fluid, and the volume of the working cavity of the Cup (rotor). To maintain energy a part of the working fluid (liquid or gas) is removed from the working chamber Cup (rotor) through the axial discharge port. The increased power of the turbine can be carried out, for example, through the use of multiple inlet connections and, accordingly, several tangential inlet devices. The flow of the working fluid can be introduced through the inlet devices spaced around the circumference and having individual or General, through the annular manifold, the supply of liquid or gas.

Figure 1 shows the design of the turbine section, figure 2 is a top view of the turbine.

The rotor is made in the form of Cup 1, is placed in the cylindrical housing 2, through a tangential inlet pipe 3, is placed on the periphery of the housing 2, is supplied working fluid (liquid, gas). The tangential flow of the working fluid on the wall of the Cup 1 near its open end secured by passing it through an axial helical guide element 4. The resulting vortex is exchanged rotational momentum with a glass of 1 by addition of the vector momentum of the working fluid and reaction forces, internal powerprotection 1. After the momentum exchange of the working body loses angular velocity and centrifugal force and replaced by a new portion of the working fluid in the radial direction to the center (axis) of the glass. Accumulated in the centre of the Cup 1 working fluid exits through the cylindrical axial exhaust pipe 5, the inlet of which is placed in the cavity of the Cup 1. The working body after tangential inlet pipe 3 passes through the axis of the spiral guiding element 4 to the inner cylindrical surface of the Cup 1, reaches the bottom of the glass 1, and then spirally moves to the axis of the Cup and to the exhaust pipe 5. Movement to the axis of the Cup 1 is with a gradually decreasing radius helix. Cross section of a tangential inlet pipe is made rectangular, and the axial vent - round.

The proposed turbine is simple in manufacturing, noiseless in operation, as it does not contain additional mechanically interconnected elements, and there is no modulation of the flow of the working bodies of those elements.

1. Turbine containing cylindrical body located at its periphery tangential inlet for the working fluid and located in the center of the axial discharge port, and also mounted on the shaft of the rotor, wherein the rotor is constructed in the form of closed with one con is and cups, the tangential inlet nozzle provided with an axial spiral guiding element with the possibility of tangential supply of the working fluid on the wall of the Cup near its open end, and an axial discharge port placed its inlet in the cavity of the Cup.
