Disclosed herein are linear hydraulic turbines in which the linear machine converts the majority of available energy in the flowing water into useful torque directly in the runner, leaving the outflow with very little velocity.

An apparatus for generating electricity from water flow held behind a barrier includes a convergent section connected to a first end of a mixing tube such that a venturi is defined between the end of the convergent section and the mixing tube; a diffuser section connected to a second end of the mixing tube, the diffuser section configured such that the pressure at the exit of the diffuser section is greater than the pressure at the venturi; and a turbine tube comprising a blade assembly having a plurality of blades. The turbine tube is supported in the convergent section and is rotatably mounted, the blades being attached to the inner surface of turbine tube such that water flow past the blades drives the rotation of the turbine tube.

The invention comprises an outer sphere, an inner sphere located within and movable relative to the outer sphere, a shaft attached to the inner sphere, jet impulse devices operatively connected to the equator of the inner sphere, and springs located to transmit the impulses via the shaft to the outer sphere. Both spheres are partially filled with liquid, and partially filled with compressed air.

A hydropower recycle system, relating to the technical field of hydroelectric power generation, includes a turbine device, a power generating device and a rooftop water tank. A water inlet is provided at the top of the rooftop water tank. The turbine device includes a turbine housing provided above the water inlet with a water outlet being provided at the bottom of the turbine housing. A turbine is provided inside the turbine housing with a turbine rotating shaft passing through the turbine housing. One end of the turbine rotating shaft is transmittingly connected to an input shaft of the power generating device. A high-pressure nozzle is fixedly disposed on a sidewall of the turbine housing. The hydropower recycle system has the advantages of small commitment resources, short installation and debugging time, and slight influence on the environment.

A hydraulic turbine motor has a rotor housing and a rotor rotatably supported in the rotor housing that defines a plurality of rotor chambers arranged circumferentially about the rotor in which each rotor chamber has a respective outlet port. Injectors are supported at circumferentially spaced locations about the housing so as to be arranged to inject hydraulic fluid in a generally tangential direction relative to the rotor axis into selected ones of the rotor chambers in which the injectors include first and second injectors. A valve mechanism is configured to open any outlet port in which the respective rotor chamber is in communication with one of the first injectors and to maintain closed any outlet port in which the respective rotor chamber is in communication with one of the second injectors.

A method and arrangement for maintaining fluid flow pressure in a system at a preset, almost constant level. One application is an impulse turbine's nozzle valve, which automatically maintains the system pressure essentially constant so that it does not depend on occasional variation of the pumped inflow, resulting that also the jet from the nozzle remains constant and its kinetic energy optimal. The nozzles independently maintain system pressure when the inflow varies.
