An adapter element for a solenoid valve assembly in an irrigation system includes an integral water turbine generator including an impeller positioned in an outlet flow path of a solenoid assembly thereof such that the impeller rotates when water flows to generate electricity.

In a rotating electrical machine apparatus, a rotor portion provided in a cylindrical portion and a stator portion provided in a recessed portion in which the rotor portion is housed are aligned along the rotation axis of a rim such that a force is generated in a direction opposite to the direction of a load that acts along the rotation axis of the rim of loads that act on the rim following rotation of a blade.

A fluid cylinder for a reciprocating pump includes a body having inlet, outlet, and plunger bores. The inlet and outlet bores extend coaxially along a fluid passage axis. The plunger bore extends along a plunger bore axis that extends at an angle relative to the fluid passage axis. The body includes a crossbore at the intersection of the fluid passage axis and the plunger bore axis. The crossbore intersects the inlet, outlet, and plunger bores at respective inlet, outlet, and plunger bore ends. The inlet bore end and outlet bore ends are connected to the plunger bore end at respective first and second corners of the crossbore. The first corner includes a first linear bridge segment connected to the inlet and plunger bore ends by corresponding curved segments. The second corner includes a second linear bridge segment connected to the outlet and plunger bore ends by corresponding curved segments.

It is disclosed a device (1) for generating electric energy from a pressurized fluid (4) comprising a stator (2), which includes a tubular body on which a solenoid (21) is wound, and a rotor (3) mobile housed inside the tubular body of the stator (2). The rotor (3) comprises a ring-shaped support element (6) and a plurality of hydraulic blades (57) each provided with a respective magnet (5) and mounted on the supporting element (6), integral with it. The rotor (3) is rotated within the tubular body of the stator (2) by the pressurized fluid (4) entering the device (1), so that the magnets (5) of the hydraulic blades (57) generate a magnetic field (22) which induces electric energy in the solenoid (21) of the stator (2).

An adapter element for a solenoid valve assembly in an irrigation system includes an integral water turbine generator including an impeller positioned in an outlet flow path of a solenoid assembly thereof such that the impeller rotates when water flows to generate electricity.

A charging assembly includes a conduit assembly configured to be fluidly coupled with a pre-existing conduit through which a liquid flows, and a hydroelectric generator coupled with the conduit assembly such that at least part of the liquid flowing through the pre-existing conduit flows through the hydroelectric generator. The hydroelectric generator is configured to create an electric current based on flow of the liquid through the hydroelectric generator. The assembly also includes an energy storage assembly conductively coupled with the hydroelectric generator. The energy storage assembly is configured to store electric energy of the electric current created by the hydroelectric generator.

The present invention provides a booster apparatus (10) for entraining gas in a flowing second fluid. The booster apparatus comprises a booster housing (116) for receiving a fluid. The booster apparatus has at least one inlet (123) through which a first fluid passes to be entrained in the second fluid when the second fluid is flowing through the booster housing. The present invention also provides a booster assembly (12) comprising a booster apparatus (10) and a fluid motive mechanism such as a turbine unit (11).

A wind and water power generation system is presented. The wind and power generation system has a roof mounted gutter system with an internally integrated turbine. The internally integrated turbine has a connection to an externally positioned wind scope. Thus, the rain run-off causes the internal turbine to rotate to generate power and the external wind scope allows the internal turbine to turn without rain.

The hydraulic generator includes a first structure; a second structure, such that a water passageway from the inflow port to the outflow port is formed by the first structure and the second structure in a state that the second structure is attached to the first structure; a water turbine; and an electrical generator. The second structure is removable from the first structure, and includes a fixing portion fixing the fixed shaft.

A method and device are provided for generating electricity from a body of water including a power generating tube having inside walls, outside walls, a top and an inlet at the bottom. The tube includes a neck comprising an inlet to the bottom and an outlet open at the top. A gate valve blocking the inlet is opened by remote control signals. Alternatively, an explosive plug blocking the inlet is removed by an explosion initiated by a remote control device. The power generating tube loaded with a means for generating electricity and empty of water is installed in the water with the inlet located deep in the water below the top that is positioned above the surface of the water.
