20090074567 | Positive-displacement turbine engine - The invention attains frictionless positive displacement by keeping its flat rectangular turbine blades constantly in lateral orientation throughout engine shaft rotation, the blades within a close-fitting combustion channel that accordingly widens and narrows so as to accomplish intake, positive compression, combustion, expansion and exhaust continuously during every rotation. The turbine blades are kept mutually parallel by means of an integral crank on every blade-supporting rod's opposite end, all cranks positioned by a disk constrained to rotate about an offset axis, in synchronism with the rotor. The invention operates at the rotational speed range of piston engines. Free of piston engines' gross internal sliding friction, therefore needing no cooling system, the invention will double the fuel economy of piston-powered automobiles, trucks and motor vessels. Light in weight, it can directly replace geared gas turbines in aircraft. It offers long service life without oil changes or periodic maintenance other than air-filter replacement. A regenerative braking system that utilizes the slightly modified invention is described. Air-cycle air-conditioning employing the slightly modified invention is described. | 03-19-2009 |
20090116954 | PITCH CONTROL RING FOR STATOR VANES OF A TURBOMACHINE - A turbomachine including a variable-pitch stator vane stage. A control ring that is coaxial around the casing comprises two segments that are assembled together by side connection straps fastened on either side of the segments with mutual insetting and in the vicinity of the ends of the segments. | 05-07-2009 |
20100021285 | Gas turbine engine compressor variable stator vane arrangement - A compressor variable stator vane arrangement comprises at least one stage of variable stator vanes. A speed sensor measures the rotational speed of the compressor rotor. A pressure sensor measures the outlet pressure of the compressor. A second pressure sensor, a temperature sensor and a third pressure sensor measure the total inlet pressure, the temperature and the ambient pressure at the inlet of the gas turbine engine. A processor determines a target operating line as a function of ambient pressure and total inlet pressure. The target operating line is defined to ensure the gas turbine engine operates simultaneously at both the minimum required compressor speed and the minimum required compressor outlet pressure when commanded to idle to minimise idle thrust and fuel burn. The processor determines if the operating point of the compressor, defined in terms of corrected outlet pressure and corrected rotational speed of the compressor rotor is above or below the target operating line of the compressor. The processor adjusts the angle of the variable stator vanes to make the operating point operate on the target operating line. | 01-28-2010 |
20100119358 | FLUID-POWERED MOTORS AND PUMPS - Fluid-powered devices are detailed. The devices may be utilized as motors or pumps, for example, and are capable to switching dynamically between these functions. They additionally may use surface-area, rather than solely pressure, differentials to produce rotary motion. | 05-13-2010 |
20100196142 | POWER GENERATING APPARATUS USING FLUID - It is about a power generating apparatus using fluid, which can obtain maximum power from natural energy with converted rectilinear motion into rotary motion, such as water. As the present invention, the apparatus using fluid includes; a bucket to put fluid in for loading itself; an Opening-and-shutting valve, which installed under the bucket to control the direction of water; a controller of opening and shutting, which connected with the opening-and-shutting valve for opening and shutting the valve; a motion converter, which connected with the bucket for convert rectilinear motion of the bucket into rotary motion; as well as subsidiary equipments for connection for connect the bucket to the motion converter. | 08-05-2010 |
20130216358 | ROTOR ASSEMBLY FOR A TURBINE - A rotor assembly for a turbine includes a substantially enclosed, cylindrical outer housing that is shaped to define an interior cavity into which a rotor is disposed. The rotor includes a main rotatable shaft in coaxial alignment with the outer housing and a plurality of pivotable blades, each blade being connected to the shaft by upper and lower spokes. In use, fluid flow enters into the interior cavity through a selectively enclosable inlet port in the outer housing, applies force to blades within the primary fluid flow path which causes the main shaft to rotate, and exits the interior cavity though a selectively enclosable outlet port in the outer housing. As the main shaft rotates within the outer housing, a control mechanism maintains each blade in a position of limited resistance when located outside the primary fluid flow path in order to maximize efficiency. | 08-22-2013 |
20130251512 | ROTARY VALVE UNIT FOR TURBOCHARGER - A turbocharger system is disclosed, including a turbine and compressor and a rotary valve unit. The rotary valve unit comprises a fixed valve seat and a rotary valve member arranged coaxially with the valve seat. The valve member is disposed against the valve seat and is rotatable about the axis for selectively varying a degree of alignment between respective orifices in the valve seat and valve member. The valve unit includes a valve housing that defines a first flow passage and a second flow passage, and the valve member and valve seat are disposed in the second flow passage. A turbocharger system is also disclosed, including a turbine and compressor and the rotary valve unit. The rotary valve unit is coupled with the turbine such that exhaust gas that has passed through the turbine wheel is fed into the first flow passage of the rotary valve unit, and exhaust gas that has bypassed the turbine wheel is fed into the second flow passage of the rotary valve unit. | 09-26-2013 |
20130302145 | WIND TURBINE - A vertical axis wind turbine having multiple blades in which the root of each blade is oriented at an angle to a radial direction from a drive shaft and at least a portion each blade is swept back. The blades preferably have a symmetric partial aerofoil shape of generally V-shaped cross section of generally constant cross section. | 11-14-2013 |

20160186766 | HOUSEHOLD FAN WITH GUSTS AND VARYING AIRFLOW - A household fan for providing the feel of a natural breeze includes a motorized impeller for providing airflow, a controller, an interface, and a breeze setting. The controller is coupled to the motorized impeller for changing one or more characteristics of the airflow. The interface is in communication with the controller for receiving human instructions for the controller. The breeze setting may be selected by way of the interface and implemented via the controller to operate the motorized impeller. When functioning in the breeze setting, the motorized impeller changes volumetric flow rate of the airflow with respect to time. | 06-30-2016 |
