That is, gas of a high pressure flows into minute intervals generated in the upper and lower inner surfaces of the rotating body and the housing, and this flows out through the bearing structure of the rotating shaft or the upper and lower covers, thereby allowing the turbine to respond to the gas pressure. It becomes a problem that efficiency falls.

On the other hand, the inlet and outlet formed on both sides of the housing is formed in a horizontal bar, there is a problem that does not smoothly discharge when discharging the gas through the outlet. That is, as the gas forcibly guided by the rotary blades and the discharge port for discharging it are made close to the vertical structure, it is impossible to discharge smoothly due to obstacles such as eddy phenomenon.

Therefore, due to various factors, the efficiency of the conventional turbine structure is significantly reduced with respect to the incoming gas pressure is urgently required for the turbine structure to create a higher efficiency and efficiency.

Hereinafter, the specific operation of the present invention will be described in detail with reference to the accompanying drawings.

5a, 5b, and 5c is a state diagram of a vane turbine to which the present invention is applied, and illustrates the inflow and outflow of gas and the rotation and vane action of the rotor according to the present invention.

First, as shown in FIG. 5A, when gas is introduced through one inlet 12A of the housing 10, the vanes 50 are pushed by the pressure to rotate the rotating body 40. As the gas collides with the ratchet groove 42 formed on the outer circumferential surface of the whole 40, the rotational force is further improved. That is, the rotational efficiency is improved compared to the conventional circular rotating body 40.

As the gas flows in and rotates the rotor 40 at the pressure, the next vane 50 passes through the inlet 12A and forms a space enclosed by the front and rear vanes 50. The action is continuous.

As shown in FIG. 5B, while the rotating body 40 is rotated while maintaining a closed space by the front and rear vanes 50, the elliptical rotating chamber 11 is rotated from the short axis direction of the first elliptical rotating chamber 11. As it is rotated in the major axis direction of the front and rear vanes 50 maintains a state in close contact with the outer surface of the rotary chamber 11 by the elastic force of its own spring (S).

Therefore, while the closed space partitioned by the front and rear vanes 50 is maintained, the volume of the space closed by the elliptical phase increases, which in turn serves to reduce the gas pressure.

As shown in FIG. 5C, the enclosed space is continuously rotated past the long axis direction of the rotary chamber 11 and rotated in the other short axis direction, and a discharge port 13A is formed in the other short axis direction.

At this time, the front and rear vanes 50 are in close contact with the inner surface of the rotary chamber 11 as they approach the outlet port 13B in the other short-axis direction to maintain a closed space.

As the enclosed space partitioned by the front and rear vanes 50 is rotated in the short axis direction through the long axis direction of the rotary chamber 11, the space becomes smaller and the gas pressure introduced therein becomes larger. The gas is discharged through the outlet 13B immediately before being equal to the pressure generated at the initial inlet while maintaining a state smaller than the generated pressure, thereby maintaining a small pressure at all times to achieve smooth rotation.

When the first vane 50 passes through the outlet 13B, gas in the enclosed space begins to be discharged, and this discharge continues until the following vane 50 passes through the outlet 13B.

At this time, the gas is more smoothly discharged by the induction groove 14B.

The vane 50 passing the outlet receives gas again from the neighboring inlet 12B as soon as it passes the short axis of the elliptical rotation chamber 11, and continuous rotation is performed.

As described above, the rotating body 40 rotates in the elliptical rotating chamber 11, but is rotated in close contact with the peak in the short axis direction of the rotating chamber 11, and the inlets 12A formed on both sides of the peak in the short axis direction. 12B) and outlets 13A and 13B allow for smooth inflow and outflow of gas.

 At this time, each vane 50 is maintained along the inner surface of the elliptical rotating chamber 11 to maintain a closed space, which is not only continuously made by the neighboring vanes 50, but also in both directions At the same time.

Therefore, according to such a structure, the rotational efficiency of the vane turbine is greatly improved.

On the other hand, a minute gap is formed between the upper and lower surfaces of the rotating body 11 and the inner surfaces of the upper and lower covers 20 and 30, and the gas lost to the outside is prevented from the sealing means to further improve rotational efficiency. Is improved.

That is, the sealing means has a structure of the inner and outer seals 23 and 24 (33 and 34) coupled to the inner and outer grooves 21 and 22 (31 and 32) of the upper and lower covers 20 and 30, respectively. The inner and outer seals 23 and 24 and 33 and 34 are formed on the upper and lower surfaces of the rotating body 40 and the upper and lower surfaces of the housing 10 with a constant elastic force by the springs S of a plurality of points. While being in close contact, the internal gas pressure is prevented from being lost to the outside.

As described above, the vane turbine according to the present invention not only improves the rotational force because gas pressure introduced from the inlets 12A and 12B pushes the vane 50 as well as the ratchet grooves 42, and the inner and outer seals 23. The efficiency of the turbine with respect to the gas pressure is improved by preventing the gas pressure from being lost to the outside by the sealing means by (24) (33, 34).

In addition, the gas pressure rotated by the elliptical rotating chamber 11 always maintains a smaller state than the inflow gas pressure, thereby improving rotational efficiency, and at the same time, more smooth discharge through the discharge induction grooves 14A and 14B. This provides a vane turbine with improved overall functionality.

Therefore, the rotational efficiency of the turbine with respect to the gas pressure is improved as a whole, thereby achieving a structure in which the power efficiency of the driving device coupled to one side of the rotating shaft is further improved.

As described above, the present invention has been described with reference to the embodiments illustrated in the drawings, but this is merely exemplary and will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. will be. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

As described above, according to the vane turbine of the present invention, the rotating chamber of the housing is formed in an elliptical shape, and by installing a rotating body in which the plurality of ratchet grooves and the plurality of accessible vanes are arranged at equal intervals in the rotating chamber, As the ratchet groove improves the rotational efficiency and the sealing property of the space partitioned by both vanes is improved, a very useful effect of the turbine efficiency is further improved.

In addition, by further forming a sealing means consisting of inner and outer sealing on the inner surface of the upper and lower cover to effectively prevent the loss of gas pressure and at the same time to form an inclined discharge induction groove on the inner surface of the rotating chamber to increase the efficiency of the turbine A very useful effect that is further improved is exerted.
