The cavity has the purpose to resist the free flow of the fluid to result pressure and impulsion on it so that it moves the shaft of the turbine. The path of the working fluid in each cavity is shown in figure 3 by arrows 3 indicating the admission of the fluid into the disc and its way out to the atmosphere through the exhaust port 4. The opening in the centre of the disc 5 is filled by the shaft. The geometry and dimensions of the cavities and the number of them in the "Pelton type" disc are any. It can, for example, have an elliptical geometry like shown in figure 3, a circular one or any another geometry, since it supplies the effect of impulsion on the cavity.

Both the phenomena, that means, adherence of the fluid to the surface of the disc characteristic of the Tesla turbine and impulsion characteristic of the Pelton Wheel , takes place in the cavities. The number of discs used in a turbine like its dimensions be "Pelton type" or smooth discs vary depending on the power that one wishes to obtain from the turbine. These construction parameters like others ones are common to both original Tesla and Hybrid Tesla-Pelton Wheel turbines; Thus the turbines are differentiated by the insertion of the "Pelton type" discs into the Tesla Turbine and, consequently the increase of the torque.

Figure 4 shows the smooth side 1 of the "Pelton type" disc 2 assembled together with other discs of the same type. As shown in figure 4, joining the side of the "Pelton type" disc, which have cavities, and the smooth side of another "Pelton type" disc, these cavities become some ducts 3 by where the working fluid enters and goes through, from the end of the discs to the exhaust ports 4, near the centre of the disc where it exits to the atmosphere. The jet fluid which goes into the discs compresses the cavity before going out by the exhaust ports in the same way that occurs when a spray of water hits on the blades of the Pelton Wheel.

It is also possible to mount the "Pelton type" disc joint together a disc with both smooth faces discs used in the original Tesla turbine.

One must note that in the walls of the duct inside cavity , by which flows the fluid, occurs also the adherence effect of the fluid so that there are present the phenomena or principles of working of the Tesla turbine and the Pelton Wheel. The smooth side of the "Pelton type" disc, if not used to cover the cavity of another "Pelton type" disc, also presents the adherence effect like the smooth discs used originally in the Tesla turbine. The assembly of a turbine with only "Pelton type" discs also results in a Hybrid Tesla-Pelton turbine, because it mixes the two principles of working in a single disc.

The mixture of "Pelton type" discs with the smooth discs used in the original Tesla turbine allows to change the proportion between speed and torque, that means, more "Pelton type" discs increase torque and reduce speed and vice versa. This property allows the designer to adapt the turbine to the applications. In the case of the "Hybrid Tesla-Pelton Wheel" Pump or Compressor, the machine is similar to the Tesla Pump or Compressor, except by the discs that are all or partially replaced by the new "Pelton type" discs.

The operation occurs in the reverse way of the turbine, that means, the fluid to be pumped or compressed goes into the admission inlet near the centre of the disc used as an exhaust port by Tesla turbine and exits at the end of the discs. The pumping or compression effect is obtained by turning the shaft and occurs due to the sum of the two effects, that means, the adherence effect of the fluid to the surfaces of the discs together with centrifugal forces, like in the Tesla Pump or Compressor and the transfer of cinematic energy from the disc to the working fluid, once the cavities pushes the fluid.

The spin of the shaft can be obtained by using any motor or even a Tesla turbine. Ref document number : Country of ref document : EP.

Kind code of ref document : A1. Country of ref document : CA. Country of ref document : US. Country of ref document : MX. Ref country code : DE. Utility Model Patent for a hybrid turbine that consists in a Tesla turbine improved with the replacement partial or total of its smooth discs by innovative discs called 'Pelton type discs 2 '.

The Tesla Turbine

The parts of the Tesla turbine are: stator, shaft, inlet, exhaust outlet 4 and smooth discs 2. The disc 2 with an innovative format, object of this patent, owns the characteristics of the Pelton Wheel, once it owns cavities 1 that are hit by the working fluid. The 'Pelton type' discs 2 have as purpose to increase the torque provided by the shaft of the turbine and it is an improvement of the Tesla turbine that makes it useful for many applications and improve its efficiency in applications which demands bigger torque that furnished by the original Tesla turbine.

The proportion between 'Pelton type' discs 2 and smooth discs, used in the turbine, defines the increase of torque. The Hybrid Tesla-Pelton Wheel can be used like a pump, compressor or vacuum pump if operates in reverse way, that means, the working fluid goes into the openings near the centre 3 of the discs 2 and goes out at the ends of the discs 2 effect that is obtained turning the shaft by a motor. Figure 1 shows the side view of the original Tesla turbine. Figure 2 shows the frontal view of the original Tesla turbine. The Hybrid turbine is characterized by the replacement of part or all the discs of the Tesla turbine by innovative discs with the characteristics of the Pelton Wheel, allowing to joint together the two principles in the same turbine, thus resulting in an improvement of the Tesla turbine, because it increases the torque, thus improving its efficiency in application that demands bigger torque than that furnished by the original Tesla turbine, and becoming viable its.

The proportion between "Pelton type" discs and smooth discs, used in the turbine, defines the increase of torque. The "Pelton type" disc consists of a side that has cavities and by another smooth. By jointing together the side of the disc with has cavities with the smooth side of another disc, the cavities become ducts by where flows the working fluid. The geometry and dimensions of the cavity and the number of cavities are any.

Its possible, for example, to have a elliptical geometry, a circular one, a spiral one or any other geometry, since it provides the impulsion effect on the cavity. The pumping or compression is obtained by turning the shaft and occurs due to the sum of the two effects, i. The spin of the shaft can be obtained by any motor or even a Tesla turbine.
