Patent number: 11781472Abstract: A flap arrangement 10 for a turbine 2 of an exhaust-gas turbocharger 2, is disclosed, in particular for a wastegate valve of the turbine, having a spindle 100 for rotatable mounting of the flap arrangement 10 in a turbine housing 3, a lever arm 200 coupled to the spindle 100, and a flap plate 300 coupled to the lever arm 200. The flap plate 300 has a flexible part 330 in a radially outer region of the flap plate 300, such that by applying a closing force to the flap arrangement 10 when the flap plate 300 is in contact with a flap seat 500 in the turbine housing 3, elastic and/or plastic deformation of the flexible part 330 of the flap plate 300 can be caused to compensate for thermal deformation of the turbine housing 3, exhaust deposits and/or wear.Type: GrantFiled: February 1, 2022Date of Patent: October 10, 2023Assignee: BorgWarner Inc.Inventors: Marcel Golz, Jason Robert Walkingshaw, Jens Watanpour, Anna Gilbert

Patent number: 11624315Abstract: The disclosure relates to a valve assembly 10 for controlling a volute connecting opening 324 of a multi-channel turbine 500. The valve assembly 10 comprises a housing portion 300, a valve body 100 and an internal lever 200. The housing portion 300 defines a first volute channel 312, a second volute channel 314 and a volute connecting region 320. The housing portion 300 further comprises a cavity 340. The cavity 340 is separated from the volutes 312, 314 and can be accessed from outside the housing portion 300 via a housing opening 342 which extends from outside the housing portion 300 into the cavity 340. The volute connection region 320 is located between the first volute channel 312 and the second volute channel 314 and defines a volute connecting opening 324. The valve body 100 is inserted in the cavity 340 of the housing portion 300 and comprises at least one fin 120.Type: GrantFiled: November 30, 2020Date of Patent: April 11, 2023Assignee: BorgWarner Inc.Inventors: Jason Robert Walkingshaw, Ondrej Cempirek, Ivan Injac

Patent number: 11434813Abstract: The invention relates to a valve assembly (100) for a multi-scroll turbine (10) for controlling an overflow of exhaust gases between a first spiral (36) and a second spiral (38) and for controlling a bypass opening (50). The valve assembly 100 comprises a lever (110) and a valve closing element (120) which is operatively connected to the lever (110). Furthermore, the valve assembly (100) comprises a spring element (130) which is designed to pre-bias the valve closing element (120) the against lever (110).Type: GrantFiled: February 22, 2019Date of Patent: September 6, 2022Assignee: BorgWarner Inc.Inventors: Stefan Ebert, Ondrej Cempirek, Ivan Injac, Patrick Witteck, Jason Robert Walkingshaw
