A fuel system for a vehicle comprising a fuel tank having a fuel tank reservoir. A lift pump is outside of the fuel tank and includes an inlet, and first and second outlets, with the inlet being configured to receive fuel from the fuel tank. The lift pump is configured to output fluid from the first outlet at a first prescribed pressure. A venturi pump is located within the fuel reservoir and defines a venturi pump reservoir. The venturi pump includes a venturi jet including a drive inlet configured to be fluidly connectable to the first outlet of the lift pump to receive fluid therefrom. A suction inlet is configured to be placeable in fluid communication with the fuel tank reservoir and to draw fluid from the fuel tank reservoir into the venturi pump reservoir in response to fluid flowing through the venturi jet at the first prescribed pressure.

A jet pump comprising a jet nozzle for accelerating a propellant. The jet nozzle has a convergent inlet part and an outlet part connected to the convergent inlet part. The outlet comprises an inner wall diverging at an opening angle. The opening angle is designed such that a propellant flowing through the outlet part at subsonic speed is detached from the inner wall and a propellant flowing through the outlet part at supersonic speed is guided by the inner wall. An automatic, cost-effective and simple changeover of the jet pump to different pressure ratios is hence provided.

An example injector includes a first conduit defining a first flow path including a first choke for a first fluid and a second conduit defining a second flow path including a second choke for a second fluid. The second choke is defined by a converging region upstream and a diverging region downstream of the second choke. The example injector further includes a mixing region after both the diverging region of the second flow path and the first choke and configured to receive the first fluid the second fluid, and an outlet configured to allow the first fluid and the second fluid to exit the mixing region. The first and second chokes are configured to allow a constant mass flow of the first and second fluids, respectively, to flow into the mixing region independent of a pressure at the outlet.

An ozone injector device comprising a housing, a corona tube disposed within the housing and configured to generate ozone, a check-valve having a first end removably coupled to the water passageway and a second end configured to receive ozone, the second end having a cavity with a movable float contained therein, an ozone inlet fitting removably coupled to the second end of the check-valve, the ozone inlet being in fluid communication with the corona tube via a corona discharge tube such that ozone entering the water passageway through the ozone inlet must pass through the check valve, and a spring-loaded clearing piston positioned to move into and out of the water passageway directly opposite the ozone inlet, the clearing piston being biased upwards, and configured to prevent flow of ozone into the water passageway.

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.
