  • Patent number: 6860720
    Abstract: A wind power system includes a rotary drive, used in conjunction with a mechanical and self-energizing coupling system. The rotary drive can be used as a wind power system in all areas. The electromagnetic coupling system can be used in all industrial areas, in all areas and types of vehicle technology, and in all electrical engineering areas. The combination of a wind power system with a rotary drive with mechanical and self-energizing coupling system indicates that the wind force can be utilized more effectively than in the case of conventional wind-driven rotors, irrespective of the physical size. This is achieved by virtue of the blade arrangement and the special design of the housing. The self-energizing coupling system furthermore has the physical advantage that the magnet is combined in one space with the iron core and, on the other hand, a short-circuited coil is energized. The current for the electromagnetic coupling may also be taken directly from the generator stage.

  • Publication number: 20040253100
    Abstract: A drum-type rotor carries an annular row of moving blades having root portions held within a slot in the periphery of the rotor. A turbine casing surrounds the rotor and carries a static blade assembly with an annular row of static blades which, together with the annular row of moving blades, constitutes an impulse turbine stage. The static blade assembly has a radially inner static ring confronting a periphery of the rotor with a seal acting therebetween. The static blade assembly has an outer static ring which has a substantially greater thermal inertia and stiffness then the inner static ring and is capable of sufficient radial sliding relative to the casing so as to accommodate relative thermal expansion and contraction of the outer static ring and the turbine casing.

    Abstract: A centrifugal blower with an eddy blade is disclosed. The centrifugal blower includes a multiblade impeller with a plurality of blades, and a scroll casing surrounding the multiblade impeller, with a spiral passage defined between the scroll casing and the impeller to guide air radially accelerated in the impeller to an air outlet port of the scroll casing, thus discharging the air from the scroll casing through the air outlet port. The eddy blade is installed in the spiral passage at a position around the air outlet port to generate a uniform current velocity distribution of air, thus preventing generation of an eddy at variance with a main current in a stream of air.

A plurality of perforated baffle plates are installed in the annular bypass duct downstream of the stator vanes. The perforated baffle plates extend in a generally axial direction and are unevenly, circumferentially spaced apart from one another to divide a major section of the annular bypass duct into a plurality of axial flow-path segments in an asymmetrical pattern to disrupt continuity, destroy a symmetrical pattern and absorb sound energy of a spinning mode of sound pressures imbedded in the air flow downstream of the stator vanes, without substantially affecting a thrust provided by the air flow when discharged from the bypass duct.

  • Publication number: 20020110453
    Abstract: An apparatus for diverting, revectoring and accelerating a mass of gas, for example, a rapidly moving air mass traversing the landscape, wherein the apparatus comprises first and second spaced-apart upstanding walls, the first wall being disposed relative to the second wall such that the lower terminus of the first wall is disposed above the lower terminus of the second wall, thereby forming an entry inlet for high velocity air mass to pass between the walls and exit at the other end; the walls are disposed in a convergent rotation in the direction of the exit outlet of the apparatus and further, the upper terminus of the second wall being positioned relative to the upper terminus of the first wall such that an air mass flowing through the space between the first and second walls will exit the apparatus at an accelerated flow rate relative to the entry flow rate and with a vector divergent from the flow vector at the entry inlet and the walls being disposed.

    Abstract: A fan shroud is provided for a cooling fan that is partially offset relative to a core portion of a vehicle mounted heat converter. The fan shroud has an arcuate portion that is offset from the core portion. The fan shroud also has an arcuate portion and a connection portion that are not offset from the core portion. The fan shroud has an overlap ratio defined as a ratio of the portion of the fan blades covered by the fan shroud in the cooling fan to the axial depth (front end to rear end) of blades. The overlap ratio at the arcuate portion is set smaller than the overlap ratio at the arcuate portion and the connection portion.

  • Patent number: 6312222
    Abstract: At a volute casing of a centrifugal fluid machine, pressure pulsation and vibrating forces acting upon the volute casing are mitigated or cancelled so as to abate the noise from the centrifugal fluid machine. The fluid machine having an impeller 3 rotating about a rotating shaft 2 within a casing 1 and having a volute 12 fixed to the casing 1 is constructed such that radius of the vane trailing edge of the impeller 3 and radius of the volute tongue is varied in the direction of axis of rotation and inclinations, on a meridional plane, of the vane trailing edge of the impeller 3 and the vane leading edge of the volute tongue are set in the same orientation, thereby reduction in head and efficiency or occurrence of an axial thrust may be restrained to the extent possible to optimally abate the noise and pressure pulsation of the centrifugal fluid machine.

  • Patent number: 6299409
    Abstract: In a centrifugal type blower unit, a diameter of an air suction port is set to be larger than a minimum inner diameter of a centrifugal fan, and a slanting portion is formed in each blade of the centrifugal fan at a side of the air suction port so that an inner radius dimension of the centrifugal fan is increased toward the air suction port. Therefore, it can prevent sub-flow air which is sucked into the centrifugal fan from an end side of the blades in an axial direction from interfering with main-flow air which is sucked into the centrifugal fan from an inner radius side of the blades. Thus, the blower unit can reduce second noise generated therefrom without greatly reducing air-blowing capacity.
