Publication number: 20180306209Abstract: A compressor assembly includes a shaft and a compressor wheel that is supported on the shaft. The compressor assembly also includes an electric motor with a stator and a rotor. The electric motor is configured to rotate the shaft and the compressor wheel. The compressor assembly additionally includes a housing assembly configured to house the stator, the rotor, and at least part of the shaft. The housing assembly includes a first member and a second member. Moreover, the compressor assembly includes a dampener disposed between the first member and the second member of the housing assembly. The dampener is configured to elastically deform to provide dampening of a force transferred between the first member and the second member of the housing assembly.Type: ApplicationFiled: April 19, 2017Publication date: October 25, 2018Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Milan Nejedly, Vit Houst, Zbynek Oslejsek, Michal Mokos, Daniel Turecek

Patent number: 10006290Abstract: A two-sided turbocharger compressor wheel and a housing forming a diffuser for the compressor. A first side and a second side of the compressor wheel are characterized by different values of a trim and of an annulus area. A first side of the diffuser surrounds the first side of the compressor wheel, and a second side of the diffuser surrounds the second side of the compressor wheel. The first and second sides of the diffuser are characterized by different annulus area ratios. The blades of the first and second sides of the compressor wheel are angularly offset from one another. The compressor wheel is configured for greater flow through the side of the compressor wheel that faces away from a related turbine wheel.Type: GrantFiled: August 27, 2013Date of Patent: June 26, 2018Assignee: Honeywell International Inc.Inventors: Vit Houst, Daniel Turecek, Vaclav Kares, Milan Nejedly, Michal Mokos, Hua Chen, Annie Li, Michael Zhao, Wei Dai, Jose Luis Lazaro Bercianos

Publication number: 20180119708Abstract: A multi-stage compressor for a turbocharger includes a compressor housing that defines an aperture for receiving a compressor wheel for successively compressing air in first and second stages. First- and second-stage inlets are fluidly connected to the aperture in opposite axial directions, and first- and second-stage volutes extend at least partially annularly therearound so that each volute is configured to receive gas flowing generally radially outward from the compressor wheel. First and second passages fluidly connect the first-stage volute to the second-stage inlet. The passages approach the second-stage inlet from opposite radially inward directions, and are asymmetric with respect to any pair of orthogonal axes having an origin lying on the turbocharger rotary axis as viewed on a transverse cross-section that is normal to the turbocharger axis.Type: ApplicationFiled: November 3, 2016Publication date: May 3, 2018Applicant: Honeywell International Inc.Inventors: Vaclav Kares, Vit Houst, Ondrej Lednicky, Milan Nejedly, Michal Mokos, Zbynek Oslejsek, Daniel Turecek

Patent number: 9869237Abstract: A turbocharger includes a two-stage serial compressor having first and second impellers, with a crossover duct for leading air from the first impeller into the second impeller for further compression. The compressor housing also defines a bypass duct from the crossover duct to the air discharge duct from the compressor, and a bypass valve disposed in the bypass duct. Under certain operating conditions (such as high-flow, low-pressure-ratio conditions) the bypass valve can be opened to bypass the second impeller, such that the compressor behaves like a single-stage compressor. At other operating conditions, the bypass valve is closed so that the compressor provides two-stage compression for higher pressure ratios.Type: GrantFiled: August 19, 2015Date of Patent: January 16, 2018Assignee: Honeywell International Inc.Inventors: Vit Houst, Daniel Turecek, Vaclav Kares, Milan Nejedly, Ondrej Lednicky, Michal Mokos, Zbynek Oslejsek

Patent number: 9856886Abstract: An assembly can include a first radial compressor wheel that has a rotational axis and that includes a hub surface that includes an annular ridge disposed at a radius measured from the rotational axis; a second radial compressor wheel that includes a hub surface; and an annular baffle disposed at least in part between the hub surfaces where the annular baffle includes an outer surface and an inner edge that defines an opening having a central axis where the outer surface includes a surface portion to one side of the inner edge that faces the hub surface of the first radial compressor wheel, where the surface portion includes an annular channel over a radial width measured from the central axis and where the radial width spans the radius of the annular ridge.Type: GrantFiled: January 8, 2015Date of Patent: January 2, 2018Assignee: Honeywell International Inc.Inventors: Vaclav Kares, Vit Houst, Ondrej Lednicky, Michal Mokos, Milan Nejedly, Zbynek Oseljsek, Daniel Turecek

Patent number: 9777737Abstract: An assembly can include a compressor housing, an adjustable wall disposed within the compressor housing that defines an air inlet to an inducer portion of a compressor wheel, and an adjustment mechanism to adjust the wall and thereby adjust at least a diameter of the air inlet. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.Type: GrantFiled: November 13, 2012Date of Patent: October 3, 2017Assignee: Honeywell International Inc.Inventors: Vit Houst, Josef Ferda, Milan Nejedly, Daniel Turecek

Publication number: 20160238012Abstract: A radial-radial compressor includes an inlet-adjustment mechanism in an air inlet for the compressor, operable to move between an open position and a closed position in the air inlet. The inlet-adjustment mechanism includes a tubular sleeve that is movable in the air inlet with an axial component of movement for adjusting a spacing distance of a trailing edge of the sleeve from an inducer portion of the wheel. In an “on” position the spacing distance is relatively greater, while in the “off” position the spacing distance is relatively smaller and the sleeve therefore reduces an effective inlet area into the inducer portion of the wheel, relative to the effective inlet area in the “on” position.Type: ApplicationFiled: February 18, 2015Publication date: August 18, 2016Applicant: Honeywell International Inc.Inventors: Milan Nejedly, Vit Houst, Daniel Turecek
