Patent number: 10570905Abstract: A centrifugal compressor for a turbocharger includes an inlet-adjustment mechanism in an air inlet for the compressor, operable to move between a closed position, an open position, and a super-open position. The compressor also includes a ported shroud system. The inlet-adjustment mechanism includes a plurality of blades disposed about the air inlet and movable radially inwardly and outwardly for defining the various positions. In the closed position, the effective diameter of air inlet is reduced and the blades block flow through the ported shroud system. In the open position, the blades still block the ported shroud but the effective inlet diameter is increased relative to the closed position. In the super-open position, the blades unblock the ported shroud so that an additional amount of flow can pass through the ported shroud, thereby shifting the compressor's choke flow line to higher flow rates.Type: GrantFiled: August 11, 2017Date of Patent: February 25, 2020Assignee: Garrett Transportation I Inc.Inventors: Hani Mohtar, Stephane Pees, William Joseph Smith, Junfei Yin

Patent number: 8690524Abstract: Various embodiments of ported-shroud centrifugal compressors are described. In some embodiments a wall of a compressor housing defines a pair of bulb-shaped hollow spaces or “bulbs”, one located proximate the compressor wheel and the other spaced upstream from the wheel, and having a connection therebetween. The downstream bulb is connected to the main flow path of the compressor by a port slot through the wall. The upstream bulb is connected to the inlet area of the main flow path by a passage through the wall. The bulbs can provide acoustic wave cancellation through multiple internal reflections in various directions. In one embodiment, the upstream bulb has a second passage connected to it, facing axially upstream, for receiving a portion of the total flow in a choked-flow operating regime, and conducting that portion through the upstream bulb, through the connection to the downstream bulb, and through the port slot into the main flow path.Type: GrantFiled: October 6, 2010Date of Patent: April 8, 2014Assignee: Honeywell International Inc.Inventors: Junfei Yin, Romil Tanna, Stephane Pees

Patent number: 8272832Abstract: A centrifugal compressor for compressing a fluid comprises a compressor wheel having a plurality of circumferentially spaced blades, and a compressor housing in which the compressor wheel is mounted. The compressor housing includes an inlet duct through which the fluid enters in an axial direction and is led by the inlet duct into the compressor wheel, and an inner surface located radially adjacent the tips of the blades. A bleed port is defined in the inner surface of the compressor housing at a location intermediate the leading and trailing edges of the blades, for bleeding off a bleed portion of the fluid, the bleed port leading to a recirculation flow channel that feeds the bleed portion back into the inlet duct. Highly cambered vanes are disposed in the recirculation flow channel for turning the bleed portion to take out and in some cases reverse the swirl in the bleed portion.Type: GrantFiled: April 17, 2008Date of Patent: September 25, 2012Assignee: Honeywell International Inc.Inventor: Junfei Yin

Patent number: 7942625Abstract: A housing is incorporated as part of a compressor having blades that impart to a fluid a momentum along a main gas flow direction and a swirl. The housing includes a channel that has at least one channel wall and defines an axis substantially aligned with the main gas flow direction. The channel is configured to duct at least some of the fluid. The channel wall defines an internal cavity that extends axially within the channel wall. A bleed passage connects and provides fluid communication between the channel and the cavity. The channel wall defines a plurality of injection passages providing fluid communication between the cavity and the channel at a location spaced in a direction opposite the main gas flow direction from both the bleed passage and the blades. The injection passages have a portion configured to direct fluid from the cavity into the channel with a component along the main gas flow direction and a component opposed to the swirl.Type: GrantFiled: April 4, 2007Date of Patent: May 17, 2011Assignee: Honeywell International, Inc.Inventors: Borislav Sirakov, Nicolas Deschairattes, Junfei Yin, Nick Nolcheff, Gary Vrbas, Dennis Thoren

Publication number: 20090255250Abstract: A switch valve for an exhaust gas-driven turbocharger system comprises a valve body defining an inlet passage, an outlet passage, and a generally annular volute in fluid communication with the outlet passage via a plurality of openings extending generally radially inwardly from the volute. A valve seat is disposed adjacent the outlet passage. A movable valve member is slidable between an open position spaced from the valve seat and a closed position engaged with the valve seat. The volute is bounded on a radially outer side by an outer wall extending about the circumference of the volute. The inlet passage enters into the volute at a first circumferential location. At a second circumferential location diametrically opposite from the first circumferential location, the volute has a dam presenting a substantial impediment to circumferential flow.Type: ApplicationFiled: April 11, 2008Publication date: October 15, 2009Inventors: Junfei Yin, Philippe Renued, Peng Yuan
