A power unit including an enclosed housing, a shaft passing through the central section of the enclosed, a motor located outside the housing and mounted to the first end of the shaft, a turbine located inside the housing and mounted into the shaft, the turbine includes a hub, a top end, a bottom end, and blades, sealing fins located at the bottom end of the turbine; and a pump located inside the housing and mounted on the turbine. The pump includes fins that are inserted in grooves located on the hub of the turbine. The fins of the pump are joined to the blades of the turbine creating that the pump, turbine, and shaft move as unitary unit. The fins of the pump maintained by two spaced crowns by insertion form cells that guide a flow of fluid. A space free of fluid with a defined volume occupies the bottom end of the pump. In a non-working position, the space free of fluid has a cylindrical shape. In a working position, because of rotation of the fluid, the space free of fluid has a paraboloid shape. The rotation of the fluid at a minimum angular velocity creates a virtual barrier, and generates a thrust.

Embodiments of the present invention relate to a steam turbine in which unnecessary axial force is reduced. The steam turbine is capable of preventing a working fluid discharged from each nozzle-equipped rotary body from acting as resistance to the nozzle-equipped rotary bodies. The steam turbine includes a housing, a turbine shaft supported pivotably in the housing, a nozzle-equipped rotary body, and a guide panel. The nozzle-equipped rotary body is in the shape of a plurality of disks stacked along the axial direction of the turbine shaft, is integrally coupled to the turbine shaft, and has at least one or more nozzle holes formed therein so as to rotate as the working fluid is ejected. The guide panel is positioned at the rear end in a flow direction of the working fluid of the nozzle-equipped rotary body and fixed to the housing to guide the flow of the working fluid.

A centrifugal radial turbine includes at least one support disc having a first face bearing at least one radial rotor stage formed by an array of blades arranged in succession along a respective circular path. The disc has through induction channels situated in a position radially external with respect to a respective shaft and radially internal with respect to the radial rotor stage. At the respective through induction channels, the disc includes a plurality of induction rotor blades of at least one respective axial rotor stage.
