20090003998 | COMBUSTORS FOR USE IN TURBINE ENGINE ASSEMBLIES - An engine assembly includes a scroll assembly including an inlet, an outlet, an inner section, and an outer section. Each of the inner section and the outer section extend between the inlet and the outlet with the outer section being longer than the inner section. The engine assembly further includes a combustor having an entrance for receiving fuel to be mixed with air and combusted in the combustor, an exit coupled to the inlet of the scroll assembly for delivering the combusted air-fuel mixture, including a hot stream, thereto, and a wall coupled between the entrance and the exit and including a plurality of dilution holes therethrough for deflecting the hot stream toward the outer section of the scroll assembly. | 01-01-2009 |
20090290980 | MIXED FLOW TURBINE - To provide a mixed flow turbine in which supply of working fluid is designed to be supplied at a hub and a shroud, and the shape of the inlet-side edges of the blades is made to work effectively, thereby reducing incidence loss. A mixed flow turbine including blades whose leading edges are formed in a convex shape toward the upstream side; and a scroll that is a space formed upstream of the blades by a casing having a shroud that covers the radially external edges of the blades, the space being for supplying working fluid toward the leading edges of the blades, wherein the scroll is separated by a scroll partition wall into a shroud-side space and a hub-side space; and a shroud-side partition wall surface and a hub-side partition wall surface at the rear edge side of the scroll partition wall form a shroud-side inlet channel in which the working fluid flows substantially radially and a hub-side inlet channel in which the working fluid flows substantially in the same direction as the inclination direction of the hub side at the inlet of the blades between the partition wall surfaces and portions facing the partition wall surfaces, respectively. | 11-26-2009 |
20100098535 | Centrifugal blower - A centrifugal multi-blade fan has multiple blades about a rotational shaft and draws in air along the rotational shaft and then blows the air approximately perpendicular to the rotational shaft to reduce wind noise. A scroll casing encloses the multi-blade fan and defines a scroll-shaped airflow passage for directing the air blown from the multi-blade fan. The scroll casing has an intake opening and an outlet opening at a scroll end, in a downstream scroll casing portion. The scroll casing expands such that a flow passage cross-sectional area on the airflow downstream side is larger than that on an airflow upstream side. A ratio of a blade length to a diameter of the multi-blade fan is greater than or equal to 0.12, and an outer scroll casing radius, relative to the rotational axis, increases as a logarithmic spiral, its expansion angle being from 3.3° to 4.8°. | 04-22-2010 |
20110091318 | Turbine housing for an exhaust gas turbocharger of an internal combustion engine - In a turbine housing for an exhaust gas turbocharger of an internal combustion engine with at least one spiral channel, which can be coupled into an exhaust gas flow of an exhaust tract of the internal combustion engine, and a receiving space for a turbine wheel which is disposed downstream of the at least one spiral channel and can be acted upon by the exhaust gas of the internal combustion engine passing through the at least one spiral channel of the turbine housing, there is at least one partial housing including the at least one spiral channel, and a housing module which is fastened to the partial housing and has a vane structure disposed upstream of the receiving space which also includes an attachment surface for a bearing section of the exhaust gas turbocharger. The invention also resides in an exhaust gas turbocharger with such a turbine housing as well as to a method for producing such a turbine housing. | 04-21-2011 |

20130121821 | CENTRIFUGAL PUMP APPARATUS - This centrifugal blood pump apparatus includes an impeller provided in a blood chamber, a first permanent magnet provided in one surface of the impeller, and a second permanent magnet provided in an inner wall of the blood chamber, for attracting the first permanent magnet. The attractive force between the first permanent magnet and the second permanent magnet on the opening side of a sidewall of the blood chamber is set to be smaller than the attractive force between the first permanent magnet and the second permanent magnet on the opposite side of the opening. As a result, inclination of the impeller with respect to a dividing wall during pump operation can be prevented. | 05-16-2013 |

20140356153 | TWIN-SCROLL TURBOCHARGER - To provide a turbocharger capable of turbocharging efficiency and reducing cost by suppressing a rapid expansion of exhaust gas blown from an outlet of a scroll in the vicinity of an inlet of a rotor blade, a twin-scroll turbocharger ( | 12-04-2014 |
20140377059 | INTRODUCTION OF EXHAUST GAS RECIRCULATION AT A COMPRESSOR BLADE TRAILING EDGE - Methods and systems are provided for injecting exhaust gases from an exhaust gas recirculation system proximate to a trailing edge of a compressor wheel of a compressor. In one example, a compressor of a turbocharger may include an exhaust gas recirculation inlet volute within a casting of the compressor. The exhaust gas recirculation inlet volute may include an injection port positioned downstream of the trailing edge of the compressor wheel for injecting exhaust gases into intake air flow. | 12-25-2014 |
20160108928 | CENTRIFUGAL FAN AND AIR CONDITIONER HAVING THE SAME - A centrifugal fan includes: an impeller; and a scroll housing surrounding the impeller, the scroll housing having suction hole and discharge hole formed therein. The scroll housing includes: a base plate; a scroll wall connected to the base plate, the scroll wall being formed in a scroll shape from a cutoff; and a discharge wall extending from the scroll wall. In the centrifugal fan, a flow path extending portion having a flow path sectional area extending toward an air flow direction convexly protrudes in the outer direction of the scroll housing in the base plate. Accordingly, a flow path is formed to extend in two directions including a direction in which the scroll wall extends and a direction in which the flow path extending portion protrudes. Thus, the static pressure of a discharge air current can be quickly recovered, and the blowing performance of the centrifugal fan can be improved. Further, the flow path extending portion is formed to protrude from the base plate, so that it is possible to enhance utilization of space near the flow path extending portion. | 04-21-2016 |
