  • Patent number: 9784118
    Abstract: A steam valve control device of this embodiment controls a steam valve. The steam valve has: an upper cover in whose through hole a bush is installed; and a valve rod which is installed so as to penetrate through the through hole of the upper cover via the bush. The valve rod has a contact surface which is formed so as to come into mechanical contact with the bush when the steam valve is opened to a maximum opening degree. The steam valve control device has a control part. When a governor free operation is performed, the control part controls the steam valve by setting a limited opening degree limited to be smaller than the maximum opening degree as an upper limit. When a load limiter operation is performed, the control part controls the steam valve by setting the maximum opening degree as the upper limit.

    Abstract: A variable geometry turbocharger is simplified yet able to maintain pulse energy. In a first embodiment, a turbine housing is provided with a pivoting wall which pivots about a point near the entry to the turbine housing. By moving the wall about the pivot point, the effective volume of the turbine housing volute is varied, thus effectively reducing the volume of exhaust gas in the volute, allowing control of exhaust gas flowing to the turbine wheel. In the second embodiment of the invention, a rotating wedge segment within the volute is rotated from a first position to a second position, changing the effective volume of the volute and allowing control of exhaust gas flowing to the turbine wheel.

  • Patent number: 8769948
    Abstract: An exhaust gas system configured for an internal combustion engine includes a cylinder head having at least two cylinders, a single exhaust duct emerging from the cylinder head, an individual exhaust duct provided between each cylinder and the single exhaust duct, and a reservoir of fixed volume integrated in the cylinder head and coupled to the single exhaust duct via a connecting duct. A reservoir valve is provided in the connecting duct in some embodiments. According to one embodiment, a method is disclosed in which the reservoir valve is commanded to an open position when flow through the single exhaust duct is large and commanded to a closed position when flowrate through the single exhaust duct is small. In some embodiments, a turbine, with a selectable volume upstream of the impeller, is coupled to the cylinder head.

  • Publication number: 20140105722
    Abstract: A wind compressor system having one or more wind turbines and a plurality of wind compressors located proximate the one or more wind turbines. The wind compressors optimize the energy created by the wind turbines by redirecting and converging the wind from the wind compressor to the wind turbines. Each of the wind compressors comprises an obstruction having a size and shape adapted to converge the wind currents by means of a Venturi effect toward the one or more turbines thereby increasing the velocity and force of the wind hitting the wind turbine. A plurality of transporters coupled to the wind compressors. The transporters configured to move at least one wind compressors to a location that maximizes the force of the wind encountered by the turbine.

  • Patent number: 8667773
    Abstract: A turbomachine comprises a flow duct with coaxially arranged radially inner and outer endwalls, first and second sets of axially spaced rotor stages arranged between the inner and outer endwalls, and a plurality of variable endwall segments arranged along the inner endwall. The first set of rotor stages rotates in a first direction, and the second set rotates in a second direction. The first and second sets alternate in axial series along the flow duct, such that axially adjacent rotor stages rotate in different directions. The variable endwall segments are radially positionable, in order to regulate loading on the first and second sets of rotor stages by changing a cross-sectional flow area between the inner and outer endwalls.
