摘要： A reaction turbine capable of providing unidirectional rotation under a reversible fluid flow is disclosed. The turbine comprises inflow and outflow fluid channels, a turbine chamber, and a working wheel with a plurality of airfoil-shaped blades mounted transversely to the direction of fluid flow for rotation in a plane parallel to the fluid flow. A channel directs the fluid flow to the blades. In the turbine chamber, the channel has a curved configuration having opposed changes in elevation or bulges directed towards the center of the turbine in a plane parallel to the flow of fluid to optimize the angle of attack of the fluid on the blades. In one embodiment, the channel also has a V or other linear or non-linear shape in transverse cross-section in the turbine chamber to smooth and direct the fluid flow. In another embodiment, the blades have a delta or other curvilinear shape, which smooths and directs the fluid flow and allows the channel to have a simpler rectangular cross-section. The turbine is capable of achieving high speeds at which electric generators conventionally operate and is suitable for use in hydro-pneumatic, hydro, wind, or wave power systems.

摘要： A reaction turbine capable of providing high speed unidirectional rotation under a reversible ultra low head pressure and/or high velocity fluid flow is disclosed. The turbine comprises a working wheel with a plurality of airfoil-shaped blades mounted transversely to the direction of fluid flow for rotation in a plane parallel to the fluid flow. The blades are arranged in a helical configuration, a modification of a delta turbine, which ensures that a portion of the blades are always positioned perpendicular to the fluid pressure, thereby creating maximum thrust to spin the turbine and ensuring a continuous speed of rotation with no accelerations and decelerations. The skewed leading edges further reduce resistance to the turbine rotation. A channel having a rectangular cross-section may be provided to direct the fluid flow to the blades. The channel may have a curved configuration having opposed changes in elevation or bulges directed towards the center of the turbine in a plane parallel to the flow of fluid to optimize the angle of attack of the fluid on the blades. At ultra low head fluid pressures, the turbine is capable of achieving high speeds, which, for gas turbines, are the speeds at which electric generators conventionally operate. For hydro applications, the helical turbine requires minimal gearing multiplication. The turbine is suitable for use in hydro-pneumatic, hydro, wind, or wave power systems.

摘要： A rotor is provided wherein an rotor core and a jacket cooperate to provide a continuous variation of area left for fluid transit. This continuous variation of area left for fluid transit produces a continuous axial acceleration of fluid and provides a first pressure gradient. The invention also provides simultaneously for blades having a continuously varying angle provided in the area left for fluid transit and causing a second pressure gradient. The varying of the fluid transit area and the angle of the blade are designed to have the first and second pressure gradients to be complementary and maintain the pressure of the fluid substantially constant. Such a continuous varying angle of inclination of the blades provides a continuous angular acceleration of the fluid and corresponding torque. The blades of continuously varying angle of inclination rotate together with the rotor core producing the torque.

摘要： An apparatus for power production from low velocity fluid flow includes a lateral support arm assembly extending from a vertical drive shaft. A power blade is pivotally secured to the distal end of the support arm, and constrained to pivot within a defined operating angle. The center of force on the power blade is proximal to the power blade pivot, so that at the limit of travel of the support arm the thrust on the power blade moves the power blade into an over-center position, causing the power blade to pivot in retrograde fashion. The pivoted power blade then drives the support arm away from the extreme position, through a neutral position, to the opposite angular position, where the process reiterates and reverses. Thus the lateral support arm is driven continuously in oscillating, lateral motion. An exciter blade joined to the proximal end of the support arm creates a force that augments the torque created by the power blade, and drives the arm past the over-center point of the power blade, causing the power blade to rotate and drive the arm retrograde toward the neutral position. A latch maintains the exciter blade aligned with the arm as it pivots from the neutral (midline) position toward the angular limit of the arm.
摘要翻译：用于从低速流体流动产生功率的装置包括从垂直驱动轴延伸的侧向支撑臂组件。动力刀片枢转地固定到支撑臂的远端，并且被限制为在限定的操作角度内枢转。动力刀片上的力中心靠近动力刀片枢轴，从而在支撑臂的行进极限下，动力刀片上的推力将动力刀片移动到过中心位置，使动力刀片枢转以逆行方式。枢转的动力叶片然后将支撑臂驱动离开极限位置，通过中间位置到达相反的角度位置，在该角度位置，过程重复和反转。因此，侧向支撑臂以振荡的横向运动连续地驱动。连接到支撑臂的近端的激励器叶片产生增加由动力叶片产生的扭矩的力，并且驱动臂经过动力叶片的超中心点，使得动力叶片旋转并驱动臂逆向中立位置。当闩锁从中立（中线）位置朝向臂的角度限制枢转时，闩锁保持激励器叶片与臂对准。

摘要： The pump isolation valve provides a means by which the pump may be selectively isolated from the remainder of the coolant system while being compatible with the internal hydraulic arrangement of the pump during normal operation of the pump. The valve comprises a valve cylinder disposed around the pump and adjacent to the last pump diffuser with a turning vane attached to the lower end of the valve cylinder in a manner so as to hydraulically match with the discharge diffuser. The valve cylinder is connected to a drive means for sliding the valve cylinder relative to the diffuser support cylinder so as to block flow in either direction through the discharge diffuser when the valve is in the closed position and to aid in the flow of the coolant from the discharge diffuser by means of the turning vane when the valve is in the open position.
