Patent number: 11566537Abstract: A water-cooled compressor housing assembly for a turbocharger includes a compressor housing that defines an open-ended cavity extending axially downstream into the compressor housing, and a separately formed cover that is affixed to the compressor housing so as to close the open end of the cavity and thereby define a coolant passage for a liquid coolant to be circulated through. A coolant inlet and a coolant outlet are provided for supplying coolant into and exhausting coolant from the coolant passage. The compressor housing has a simplified geometry that is manufacturable by sand casting without needed a sand core for the coolant passage, or by die casting.Type: GrantFiled: October 12, 2020Date of Patent: January 31, 2023Assignee: Garrett Transportation I Inc.Inventors: Manuel Marques, Olivier Millotte, Emeric Genin, Jean-Pierre Toniolo

Patent number: 10844779Abstract: An e-charger includes an outer housing and a rotor supported for rotation within the outer housing. A motor assembly is housed within the outer housing and includes an electric motor and a motor case. The electric motor is encased within the motor case. The electric motor is configured to drivingly rotate the rotor within the outer housing. Furthermore, the e-charger includes a cooling system configured to receive a coolant. The cooling system includes a manifold passage defined in the outer housing. The cooling system includes a first motor cooling circuit and a second motor cooling circuit that are cooperatively defined by the outer housing and the motor case. The first motor cooling circuit and the second motor cooling circuit are fluidly connected to the manifold passage. The manifold passage is configured to distribute a flow of the coolant between the first motor cooling circuit and the second motor cooling circuit.Type: GrantFiled: September 11, 2018Date of Patent: November 24, 2020Assignee: GARRETT TRANSPORTATION I INCInventors: Frederic Hehn, Damien Guepin, Shankar Pandurangasa Solanki, Emeric Genin, Valerie Bribant

Patent number: 10731488Abstract: A turbine housing of a turbocharge can include a surface that defines a portion of a volute, an annular surface that extends radially inwardly to define a portion of a pressure chamber that is in fluid communication with the volute, a substantially annular plate that defines a portion of the pressure chamber, an annular component, at least one spacer that defines a minimum axial distance between the substantially annular plate and the annular component to define a nozzle that is in fluid communication with the volute and in fluid communication with a turbine wheel space where, responsive to fluid flow in the volute and through the nozzle to the turbine wheel space, the pressure chamber has a fluid pressure that exceeds a fluid pressure of the nozzle to apply a biasing force to the substantially annular plate in an axial direction toward a center housing.Type: GrantFiled: February 4, 2018Date of Patent: August 4, 2020Assignee: Garrett Transportation I Inc.Inventors: Emeric Genin, Giorgio Figura, Daniel Frank

Patent number: 8100639Abstract: An improved actuating rod end connector is connected with an actuating rod that extends from a turbocharger assembly actuator mechanism. The rod end connector has a body with an opening at one longitudinal end, and the actuator rod is disposed through the opening. An adjustment member is rotatably disposed within the body and has a threaded inside cavity in communication with the opening. The inside cavity is threadably engaged with a threaded outside surface of the actuator rod. The body includes an actuator rod opening disposed therethrough adjacent the adjustment member to receive a section of the actuator rod therein to facilitate contacting the actuator rod disposed within the body from outside of the rod end connector. An attachment opening is disposed through the body to facilitate attachment of the rod end connector with a linkage member, e.g., a linkage member connected with a movable member of the turbocharger.Type: GrantFiled: October 13, 2005Date of Patent: January 24, 2012Assignee: Honeywell International Inc.Inventors: Emeric Genin, Emmanuel Severin, Alexis Lavez, Frederic Gerard, Muller Philippe, Francois Grandjean
