Patent number: 11221054Abstract: An e-charger includes a shaft supported for rotation about an axis. The e-charger also includes a compressor wheel that is attached to the shaft. The e-charger further includes an electric motor configured to drive the shaft and the compressor wheel in rotation. Also, the e-charger includes a housing that houses the electric motor and at least part of the shaft. Moreover, the e-charger includes a dampening system incorporated in the housing and configured to dampen loads transferring through the housing. The dampening system includes at least one solid-state dampener that is resiliently flexible, and the dampening system includes at least one fluid viscous dampener.Type: GrantFiled: November 26, 2019Date of Patent: January 11, 2022Assignee: GARRETT TRANSPORTATION I INCInventors: Milan Nejedly, Vit Houst, Daniel Turecek, Pavel Krejci, Zbynek Oslejsek

Patent number: 10539160Abstract: 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: GrantFiled: April 19, 2017Date of Patent: January 21, 2020Assignee: GARRETT TRANSPORTATION I INCInventors: Milan Nejedly, Vit Houst, Zbynek Oslejsek, Michal Mokos, Daniel Turecek

Patent number: 10190596Abstract: 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: GrantFiled: November 3, 2016Date of Patent: January 29, 2019Assignee: Garrett Transportation I 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
