| 415212100 | Scroll or helical type casing with specific exit nozzle | 8 |
| 20100310363 | TURBOCHARGER - Turbulence of fluid in a turbine impeller outlet is reduced with a simple structure so as to improve efficiency of a turbine. | 12-09-2010 |
| 20100310364 | Turbine housing and method for producing a turbine housing - In a turbine housing, for an exhaust gas turbocharger of an internal combustion engine with an exhaust gas guide section which has at least one spiral channel that can be coupled to an exhaust path of an exhaust tract and a reception chamber for accommodating a turbine wheel arranged downstream of the at least one spiral channel, at least one first and one second partial housing are provided, which include complementary wall regions of the at least one spiral channel and which are joined so as to form the at least one spiral channel. Also, an exhaust gas turbocharger with such a turbine housing is provided and a method for producing such a turbine housing. | 12-09-2010 |
| 20100310365 | TURBOCHARGER - A turbocharger includes an exhaust nozzle arranged between a scroll passage of a turbine housing and a turbine impeller, a gap formed between a rear surface of the exhaust nozzle and the turbine housing, and a sealing device for closing the gap. The sealing device includes a seal member which is C-shaped, i.e., an annulus with a part cut out to provide a slit, and has an inner peripheral end arranged along the turbine housing. The seal member is configured such that, by action of gas pressure in the scroll passage, the outer peripheral end approaches the rear surface of the exhaust nozzle, slit ends approach to each other, and the inner peripheral end approaches the turbine housing, leading to reduction in diameter. With a simple structure, gas is prevented from leaking from higher to lower pressure sides through a gap between a turbine housing and an exhaust nozzle. | 12-09-2010 |
| 20110250065 | CENTRIFUGAL FAN - An exemplary centrifugal fan includes a casing defining an air outlet, and an impeller in the casing. An air channel is defined in the casing between a sidewall of the casing and outermost free ends of the impeller. The sidewall includes a first curved section adjoining a second curved section. The first curved section is located at a more upstream portion of the sidewall than the second curved section along a rotation direction of the impeller. The first curved section extends along a part of an Archimedes spiral or a part of a logarithmic spiral. The second curved section is located farther away from the impeller than an imaginary extension line of the first curved section along the Archimedes spiral or the logarithmic spiral. An air guide plate is formed in the casing and extends from the air outlet to an inner region of the air channel. | 10-13-2011 |
| 20120201670 | BLOWER FAN - A blower fan includes a motor unit including a rotary unit; a plurality of blades fixed to an outer surface of the rotary unit and arranged to be rotated about a center axis by the motor unit; and a lower plate portion defined by a magnetic body and positioned below the motor unit and the blades. The lower plate portion includes a motor fixing portion, a curved portion, a peripheral portion, and a plurality of ribs arranged to interconnect the motor fixing portion and the peripheral portion either directly or through the curved portion, the curved portion including a standing portion extending upward from the outer edge portion of the motor fixing portion and an upper surface portion extending radially outward from an upper end of the standing portion, a plurality of openings positioned below the blades being defined by the curved portion, the peripheral portion, and the ribs. | 08-09-2012 |
| 20120251315 | TURBINE HOUSING MADE OF SHEET METAL - In the neighborhood area X of the tongue part | 10-04-2012 |
| 20140178194 | BLOWER FAN - In a blower fan according to a preferred embodiment of the present invention, a side wall portion includes a tongue portion arranged to project between an air outlet and an impeller. A side surface of the tongue portion includes a tongue portion tip arranged to touch a first imaginary plane including a central axis; a first tongue portion side surface arranged to extend from the tongue portion tip along an outer envelope of the impeller; and a second tongue portion side surface arranged to extend from the tongue portion tip toward a side edge, the side edge being a line of intersection of the air outlet and the side wall portion. The second tongue portion side surface is arranged to cross a second imaginary plane including the central axis and touching the side edge. | 06-26-2014 |
| 20160115965 | DAMPER-INTEGRATED BLOWER HAVING IMPROVED AIRTIGHTNESS - The present invention relates to a damper-integrated blower having improved airtightness, which comprises a blower casing a having a suction port and a blower casing b fastened to the casing a from the opposite side; a vane stopper protrusion is formed on bottom surface of the exhaust port, and a vane contact housing part is formed above the exhaust port; damper motor screw fixing parts integrally protrude from the outer upper surface of the vane contact housing part of the blower casing a; a damper motor shaft hole is bored in a damper motor shaft hole protrusion part which is integrally formed on the outer upper side of the vane contact housing part of the blower casing a; a vane rotation shaft protrudes from the inner surface of a damper motor shaft hole protrusion part of the blower casing b facing the damper motor shaft hole protrusion part; an eccentric damper motor shaft of a damper motor is introduced into the damper motor shaft hole so as to connect with the blower casing a; a vane as a single member is connected to the damper motor shaft and the vane rotation shaft so as to open and close the exhaust port; and a gasket is coupled to the four edges of the vane providing a vane module. | 04-28-2016 |
