Abstract: A turbine blade and a radial turbine having at least one blade is provided. The turbine blade includes a trailing edge and a leading edge opposite the trailing edge. The turbine blade also includes a cooling passage defined internally within the turbine blade. The cooling passage is in fluid communication with a source of cooling fluid via a single inlet to receive a cooling fluid. The cooling passage diverges at a first point downstream from the single inlet into at least two branches that extend along the at least one blade from the first point to a second point near a tip of the leading edge and the cooling passage converges at the second point.

Abstract: A turbine, e.g., with a blade arrangement, which receives an air flow in the radial direction and which is located on a carrier surface of the turbine wheel, is used as a drive motor for a rotary atomizer. The drive channel, which contains the turbine blades and which is limited by the carrier surface, is also closed on its other side by a cover element, which is attached to the turbine wheel and which rotates with the wheel for increasing efficiency. For an additional increase in efficiency, the inlet for the drive air of the turbine is configured as an ultrasonic nozzle with a cross section that expands continuously up to the opening.

Abstract: Rotary fluid handling apparatus employing a wheel to provide multi-stage compression or expansion. A wheel having a first set of vanes includes a shroud about those vanes with a second set of vanes outwardly of the shroud. One set of vanes provides for low specific speed flow while the other set of vanes provides for high specific speed flow. A transfer passage interconnects the outlet of the first stage with the inlet of the second stage. The difference in temperature between the inlet flow to the system and the outlet flow from the system may be exchanged to increase efficiency. The multi-stage wheel and associated passages may be configured for either compression or turboexpansion.

Abstract: In a flow control apparatus of an exhaust gas turbocharger turbine for an internal combustion engine including a rotor disposed in a turbine casing having a spiral guide channel arranged around the rotor with a mouth area defining an inlet opening for directing the exhaust gas to the turbine rotor, a control sleeve including a flow guide section with flow guide passage is axially movably supported between the spiral guide channel and the rotor. The flow guide passages have guide characteristics which vary depending on the axial location on the sleeve so that the characteristics of the exhaust gas flow admitted to the rotor can be changed by axial movement of the control sleeve. Adjacent the flow guide passages the control sleeve has an integral annular end section for blocking the exhaust gas flow so as to form a flow-throttling cross-section at the mouth area for engine brake operation.

Abstract: A pump is provided within a vortex generator having a plurality of equally spaced blades which rotate in a pump casing to form a nucleus of fluid in the shape of an ellipsoid having an upper tapered end and a lower tapered end with a thicker central section at the blades. Fluid flows in a synchronized flow from the lowered tapered end of the nucleus in a rotating vortex column of fluid which initially flows out of the pump inlet to swirl the ambient fluid about the inlet and causes a low pressure area and a swirling of the ambient fluid to flow inwardly through the pump inlet in a direction counter to the vortex column flow. A belt of fluid rotates between the nucleus and the pump casing. The blades are curved to retain fluid in the nucleus and momentum energy is cumulatively applied to keep the swirling column of fluid swirling through the pump outlet. A tapered section on the pump between the pump inlet and pump outlet assists in flow therebetween. A divider may be provided in the pump casing with an opening in the divider to allow the vortex column to flow from a vortex generating chamber to a pump discharge chamber while debris hits the divider and is prevented from flowing into contact with the blades. Pressure boosters may be added to the blades.

Abstract: A method and apparatus for pumping liquid includes a pump casing with a vortex generating member which generates a swirling column of liquid which swirls about a central axis and which is directed through the pump inlet to discharge into the ambient body of liquid at which its energy is quickly dissipated. The surrounding ambient liquid is drawn through the pump inlet in a counterflow to the vortex column flow and flows into the pump casing and then out through a pump discharge. The preferred vortex generating member has channels of decreasing size converging toward the axis of the vortex column with the streams of liquid increasing their respective velocities as they flow toward the axis at which the streams join and concentrate their energies to form the vortex column. Preferably, the vortex member is driven by a power source.
