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).

An apparatus energized by a flowing fluid includes at least one turbine blade having a trailing edge angle and an elastic deformation member connected to the at least one turbine blade. The deformation of the elastic deformation member changes an orientation of a trailing edge angle of the at least one turbine blade.

A generator having a coupling adapted to couple at least two fluid conduits together; an axial flow channel defined by the hose coupling and having an axis; a conductive coil in the hose coupling enveloping the axial flow channel; a rotor rotatable relative to the conductive coil and encircled by the conductive coil; a plurality of vanes coupled to the rotor and projecting radially toward the axis, but not intersecting the axis.

An energy production device for a chargeable energy storage is arranged on a fluid conduit of an existing fluid circuit in a device through which a fluid flows. The fluid flow in the fluid conduit primarily serves a predetermined purpose different from that of the energy production device. The energy production device is arranged to produce energy from the kinetic energy of the fluid flow to charge the chargeable energy storage. A module insertable into the device may include the energy production device. The device may be a washer disinfector for processing medical instruments, systems and/or products that include at least one handpiece having a chargeable energy storage. The energy storage is configured as a rechargeable battery or as a power cell and is adapted to be processed together with the handpiece in the washer disinfector.

A hydroelectric power generation system includes a water turbine disposed in a channel that carries a flow of a fluid, a generator driven by the water turbine, and a controller that performs a first control. The channel includes a first channel located on an inflow side of the water turbine. The controller controls, in the first control, a flow rate or a head of the water turbine so that any one of a pressure of the fluid in the first channel, a flow rate of the fluid in the first channel, and a liquid level of the fluid in a first reservoir from which the fluid flows out to the first channel approaches a first target value.

Apparatuses, systems, and methods are provided for generating power. A pipe having an input flow is coupleable to an input section configured to receive at least a portion of the input flow. A generation section is coupleable to the input section and includes a pipe section to carry the at least a portion of the input flow, a turbine coupleable to the pipe section and configured to capture energy from the at least a portion of input flow carried by the pipe section, and a generator coupleable to the turbine and configured to generate power from the energy captured by the turbine. An output section is coupleable to the pipe and configured to provide output of the generation section to the pipe.

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.

A fluid flow device has a body with a mechanism for altering state of a fluid flowing through the device, an inlet conduit providing inlet of the flowing fluid to the body of the device, an outlet conduit providing outlet of the flowing fluid from the body of the device, and a micro-generator assembly installed in either the inlet conduit or the outlet conduit, the micro-generator assembly having an impeller driven by the flowing fluid, the impeller turning a shaft driving a generator producing a voltage across two output conductors.

A System for Electricity Generation Using Heat Pump and Hydro Turbine, having very high efficiency is disclosed herein. The said system comprises Circular pipes arranged in rectangular pattern to form close circuit of water (10), water pump (1)attached to first end of said closed circuit (10), heat pump, hydraulic turbines (T1(3), T2(4) and T3(5)) placed at other three corners of the closed circuit (10), heater (2). Present invention uses pressure raised after low temperature heating of water in closed circuit (10) for energy generation. The hydraulic turbines are used to capture pressure generated in the closed circuit (10) and to convert it in mechanical work. As system works on low temperature it avoids huge losses of heat energy occurring at currently available mechanisms. The system is simple in construction, compact, low in capital cost, suitable for operation with local water and over a wide range of climatic conditions.
