A disc turbocharger includes a multi-disc engine in which each disc engine includes a turbine blade, a compressor blade, and a bearing without requiring a shaft between the turbine blade and the compressor blade. The power produced by each turbine blade is consumed by its own joined compressor. The disc turbocharger has a multi-disc engine that works as a multi-stage turbocharger with a smaller size and no piping between the turbochargers. The disc turbocharger uses a waste spool valve for control of the.

A transonic two-phase reaction turbine for use with low and high temperature fluid flow mediums includes at least two wheels that are configured to rotate in opposite directions, at least one of the at least two wheels being equipped with one or multiple kinetic energy harvesters.

The present invention relates to a small-scale combined heat and power generator using a steam injector with a small-scale heat source and, more particularly, to a small-scale combined heat and power generator in which, since reaction energy of a steam injection force from nozzles (106) of a rotatable disk-shaped steam injector, which has a plurality of nozzles configured to inject steam mounted thereon, is applied to the disk-shaped steam injector and then action energy of the injected steam which returns to a steam injection plate (107) adjacent thereto by performing a U-turn after colliding with a steam reflection inducing groove (108) installed to reflect the injected steam is also applied to the disk-shaped steam injector, a rotational force of the steam injector configured to generate power is doubled without a turbine.

Disclosed is a steam turbine capable of reducing the load of a bearing supporting a turbine shaft transmitting rotational driving force of a plurality of nozzle-equipped rotary bodies arranged in multiple stages. The steam turbine includes a housing (110); a turbine shaft (120) pivotably supported by a bearing (121) in the housing; and a plurality of dish-shaped nozzle-equipped rotary bodies (130) integrally combined with the turbine shaft (120), provided with one or more nozzle holes (131) from which working fluid is ejected so that the nozzle rotations bodies (130) can be rotated, and stacked in an axial direction of the turbine shaft (120). The nozzle hole (131) is inclined with respect to a normal direction n of the periphery surface of the nozzle-equipped rotary body (130) and is inclined toward an axial direction c of the turbine shaft (120).

In this device, the nozzles that often used in order to make a linear motion, so they can be helpful in rotating the disc if they are placed at the external ring of disc. In addition, in this case, apart from generating electricity from the discharging fluid of the nozzle by ionization method, the kinetic energy of the discharging fluid can be used for rotating the disc as well.

The present invention relates to an improvement of an axial turbine. Thereto, the present invention includes a submerged turbine 100 in which a fluid is filled in an interior thereof. The present invention also includes a colliding turbine 200 for ejecting a fluid with a high pressure to rotate blades. The structure of the turbine according to the present invention includes a submerged turbine, a colliding turbine, or a combination type turbine (in which a submerged turbine and a colliding turbine are combined). Accordingly, quality and reliability of the product are significantly improved to satisfy the operator.
