Abstract: An electronically commutated hydraulic machine is coupled to a drivetrain. Working chambers of the hydraulic machine are connected to low and high pressure manifold through electronically controlled valves. The phase of opening and closing of the valves has a default. In order to avoid cycle failure due to acceleration events, for example due to backlash in the drivetrain, the phase of opening or closing of the electronically controlled valves is temporarily advanced or retarded from the default timing.

Abstract: The invention consists of a system for converting wind energy (SCEE) into mechanical and then electrical energy. This system (SCEE) is not subject to the theoretical Betz limit (59%). The system (SCEE) has a wheel (F) provided with a series of blades arranged all around it. The wheel (F) rotates in a pivot connection about a fixed axle (L). Set on the axle (L), a support (E) ensures the fastening of the end-plates of a series of double-acting actuating cylinders (D). The rods of the latter are in a ball-jointed connection with the body (A) in order to offer the latter a maximum degree of freedom in space. A rigid arm (C) is set on one side of the wheel (F) and held on the other side, in a pivot connection, on a U-shaped section piece (B). Having a circular satellite motion, the latter rotates with the wheel (F) while sliding over a peripheral region of the body (A). When the wind acts on the body (A), the latter pivots with the section piece (B) and pushes the rods of the actuating cylinders (D). Having a circular satellite motion, the section piece (B) rotates while sliding over a peripheral region of the body (A), thus changing the fulcrum of the moment of the resultant force of the wind (the pivot connection of the section piece (B)) which is applied to the body (A). The rods of the actuating cylinders (D) will consequently be pulled and pushed, while having a cyclical translational motion. Set on the axle (L), a nacelle (J) primarily contains a hydraulic motor (H) and an electric generator (G), which can be coupled via a speed-increasing gear. During the reciprocal motions of the pistons of the actuating cylinders (D), a set of valves ensures a one-way flow of hydraulic fluid in the “go and return” hydraulic circuits, whether by pulling or by pushing. The “go and return” hydraulic circuits are, moreover, linked to the hydraulic motor (H). In order to allow the system (SCEE) to be held facing the wind and to pivot on the mast (1), its orientation can be ensured by a tail vane (K) fastened, via a support, to the nacelle (J).

Abstract: A compressed-air energy storage system according to embodiments of the present invention comprises a reversible mechanism to compress and expand air, one or more compressed air storage tanks, a control system, one or more heat exchangers, and, in certain embodiments of the invention, a motor-generator. The reversible air compressor-expander uses mechanical power to compress air (when it is acting as a compressor) and converts the energy stored in compressed air to mechanical power (when it is acting as an expander). In certain embodiments, the compressor-expander comprises one or more stages, each stage consisting of pressure vessel (the “pressure cell”) partially filled with water or other liquid. In some embodiments, the pressure vessel communicates with one or more cylinder devices to exchange air and liquid with the cylinder chamber(s) thereof. Suitable valving allows air to enter and leave the pressure cell and cylinder device, if present, under electronic control.

Abstract: A wind powered sea pump comprises a propeller, rotor, one or more pumps and one or more flywheels. The present invention relates to a pump powered by the wind to move cold subsurface water from a lower level of the sea to the warmer surface water. The wind powers the rotor causing the shaft to rotate, thereby transmitting power to: one or more pumps, to pump colder sub-surface water from the depths; one or more flywheels to provide gyroscopic stability to entire platform and to a propeller to offset the force of the wind pushing back the wind powered sea pump. The hull provides a sump for a single hose connector to feed water to pumps from a pickup hose of desired diameter to a desired depth. The force of the wind powers the sea pump to transport colder water from a lower depth to the sea surface. A sea anchor provides a pivot point to keep the wind powered sea pump oriented directly into the wind and the weather vane helps with the wind orientation as well as providing space for use as an advertising bill board.

Abstract: A positive displacement pumping system for use in deep wells includes a drive system and one or two pumps. In the preferred embodiment, the drive system includes an electrical motor, a speed reducer, and a rotary-to-reciprocal motion converter. Alternatively, the drive system includes a windmill, a variable transmission, and a counterbalance. The counterbalance can be either weights or a second alternating pump. The pumps include a central hollow discharge tube and one or more vertically aligned pumping chambers in fluid communication with the central discharge tube. Within each pumping chamber, a valve arrangement, which includes a piston or shuttle member and fluid intakes, causes fluid to fill and then drain from the pumping chambers as the central hollow discharge tube reciprocates. In operation, the drive system causes the central hollow discharge tube in the pump to reciprocate and thereby cause the fluid to travel from each pumping chamber into to the central discharge tube. In the preferred embodiment, fluid is pumped on both the upstroke and downstroke of the central discharge tube. Alternatively, fluid is discharged on only the upstroke. Fluid from the central discharge tube is discharged from the pump into a discharge field. The amount of fluid discharged on each stroke depends on the number and size of pumping chambers and the length of the stroke. A greater number of pumping chambers causes a greater discharge of fluid at a higher velocity into the discharge field.
