摘要： The power plant disclosed is an engine that derives its usefulness in the pursuit of energy generation by utilizing hydrostatic pressure differentials found or created in various liquids, gases or solutions, such as but not limited to water and air. It is generally provided as a configuration designed to create a pressure differential, and to use the pressure differential to increase the effective head seen via a penstock and turbine system. Pump systems that are employed include venturi systems, jet pump systems and other comparable mixed-pressure vacuum pumps. Multiple power generating systems are interconnected to provide continuous and constant power generation through a penstock and turbine system.

摘要： The compressor compresses gas in capillaries leading to a radially distant annular container space. Centrifugal force acts on gas bubbles entrained between liquid slugs moving radially outward through the capillaries which may be radial, tangential or continuously curved. Compressed gas is collected in the annular space. A gas-liquid emulsion is fed to the capillaries by an inboard emulsification device. The emulsification may include a vortex generator, an ejector or a venturi injector, all feeding the gas-liquid mixture into the inboard ends of the capillaries. The capillaries are formed in a series of discs, coaxially stacked with outer disc ends open to the annular space. Capillary inlets may be perpendicular, tangential or may define a venturi jet.

摘要： This invention relates to the area of jet technology, primarily to liquid/gas ejector devices used for the creation of a vacuum. The technical problem, solved by the invention, is the increase of the coefficient of efficiency of the liquid/gas vacuum ejector device. This problem has been solved by this invention due to the optimization of the process of mixing gas and liquid media. This has been achieved due to the optimization of mixing gas and liquid media in the mixing chamber of the liquid/gas vacuum ejector device, containing an active nozzle (1) and a mixing chamber (2), the area of the minimal section of the latter being 201 to 800 times the area of the minimal section of the active liquid nozzle (1), and the ratio of the distance from the outlet section of the mixing chamber (2) to the outlet section of the active nozzle (1) to the diameter of the minimal section of mixing chamber (2) is in the range from 10 to 300.

摘要： An apparatus for generating a stream in a body of water has at least one cylinder installed under water, and a water-jet pump housed in the cylinder. The pump draws water in through one end of the cylinder and produces a stream of water accelerated by a driving fluid supplied from an external source. The stream is discharged through another end of the cylinder to promote a flow in the body of water.
