| 20160090993 | CENTRIFUGAL AIR BLOWER - A centrifugal air blower includes a casing having a spiral scroll, an impeller contained in the casing, an inlet side panel having an inlet, and a motor-fixing side panel fixing a motor. The centrifugal air blower further includes a first triangle wall and a second triangle wall at a discharge outlet opposite to a tongue. The triangle wall where air velocity inside the casing is slower is shaped with a longer vector component (length B) in the direction from the discharge outlet to the impeller than the other triangle wall. This configuration makes the air velocity near the discharge outlet uniform and suppresses a decrease of static pressure, an increase of power consumption, and turbulent flow noise. | 03-31-2016 |
| 20160102579 | SHEET METAL TURBINE HOUSING WITH CELLULAR STRUCTURE REINFORCEMENT - Systems are provided for a reinforcement element coupled to a sheet metal turbine housing that imparts desirable thermal-protective and structurally strengthening characteristics to the housing layers. In one example, a system may include a turbine comprising a housing surrounding a turbine rotor, the housing having an outer layer surrounding an inner layer at a distance to form an intermediate space between the inner and outer layers. Moreover, disposed in the intermediate space is a reinforcement element coupled to the inner and outer layers, providing strength and consistent rigidity without a significant increase in weight to the housing. | 04-14-2016 |
| 20160108920 | CENTRIFUGAL COMPRESSOR - Provided is a centrifugal compressor in which a malfunction such as shaft vibration due to rotating stall is suppressed, and degradation of performance due to friction losses or the like is suppressed. In a centrifugal compressor ( | 04-21-2016 |
| 20160108921 | CENTRIFUGAL COMPRESSOR AND TURBOCHARGER - A centrifugal compressor includes a housing, a wheel rotatably provided in the housing, a diffuser that decelerates compressed air and increases its pressure, a throttle portion provided between the wheel and the diffuser, and a scroll. The center of the inner peripheral edge of the diffuser is eccentric toward an area located on a winding start side of the scroll from the shaft center of the wheel toward an area. | 04-21-2016 |
| 20160131153 | INTAKE CHANNEL ARRANGEMENT FOR A VOLUTE CASING OF A CENTRIFUGAL PUMP, A FLANGE MEMBER, A VOLUTE CASING FOR A CENTRIFUGAL PUMP AND A CENTRIFUGAL PUMP - An intake channel arrangement includes an intake channel. The intake channel includes a first end with a first inner diameter, and a second end with a second inner diameter, the second inner diameter being smaller than the first inner diameter, a cross-sectional flow area and an adapter section arranged between the first and second ends, a first channel portion with a surface and the first inner diameter, an annular convex curvature surface joining at an angle to the surface of the first channel portion, the angle being 90°-110° between the surface of the first channel portion and a tangent of the convex curvature surface having a tangent point in an intersection of the surface of the first channel portion and the convex curvature surface, the annular convex curvature surface reducing the cross-sectional flow area from the first inner diameter to the second inner diameter. | 05-12-2016 |
| 20160138607 | CENTRIFUGAL PUMP CASING WITH OFFSET DISCHARGE - A pump casing having a casing body is configured with a discharge formed in the casing body where a midline of the discharge is offset from a tangent line of the casing body and offset from a centerline of the casing body, such that the midline of the discharge is located along a point between the defined centerline and defined tangent line of the casing body. | 05-19-2016 |
| 20160138608 | CENTRIFUGAL COMPRESSOR AND TURBOCHARGER - An annular diffuser is formed on an outlet side of a wheel in a housing. A spiral scroll is formed on an outlet side of the diffuser in the housing. An annular concave part is formed to be depressed to an inside in a radial direction in a boundary between a shroud-side wall surface of the diffuser and a wall surface of the scroll. | 05-19-2016 |
