Patent number: 11525390Abstract: An exhaust gas-conducting section of an exhaust turbocharger comprises a duct with a through-flow opening which can be fully or at least partially blocked or released by a closure element of a control device. The closure element is designed as a poppet valve. The closure element can be moved by an actuator can be disposed in a wall of the exhaust gas-conducting section. The closure element has a closure body with an annular section surface on its bottom surface which faces the through-flow opening. The section surface corresponds to an element seat formed in the wall. Its top surface faces away from the bottom surface and is designed in a profiled manner in order to produce a top surface at least partially corresponding to another element seat and/or to achieve flow-optimized circulation.Type: GrantFiled: June 5, 2019Date of Patent: December 13, 2022Assignee: IHI Charging Systems International GmbHInventors: Hermann Burmester, Manfred Guthörle, Daniel Senz

Patent number: 10662868Abstract: The invention relates to a regulating device for a turbocharger. The regulating device (8) is received in a turbocharger (2) exhaust gas conducting section (1) through which exhaust gas can flow, and a fluid flow to a turbine wheel which is rotatably received in the exhaust gas conducting section (1) can be conditioned using the regulating device (8). A flow channel (10; 31) which is formed in the exhaust gas conducting section (1) is to be opened and closed using a cover element (9) of the regulating device (8), and the cover element (9) is arranged on a regulating device (8) pivot arm (38) which can be pivoted about a rotational axis (34). According to the invention, the cover element (9) is designed to open and close a flow channel designed as a bypass channel (31) for bypassing the turbine wheel and/or for opening and closing a flow channel, which is designed as a through-flow opening (10), between a first spiral channel (4) and a second spiral channel (5) of the exhaust gas conducting section (1).Type: GrantFiled: February 9, 2017Date of Patent: May 26, 2020Assignee: IHI Charging Systems International GmbHInventors: Hermann Burmester, Klaus Sperling, Manfred Guthörle, Rohit Pawar, Jason Walkingshaw, Daniel Senz

Patent number: 9683456Abstract: In a heat shield for an exhaust gas turbocharger, by means of which at least a first area of the exhaust gas turbocharger is to be shielded against a second area in a heat insulating manner wherein the heat shield comprises at least one fastening structure by which the heat shield is attached to one of the housing parts of the exhaust gas turbocharger, the fastening structure is in the form of locking elements for interlocking the heat shield with the respective housing part. The invention also resides in an arrangement of a heat shield between two housing parts of an exhaust gas turbocharger in such a way that it is firmly attached to one housing part without contacting the other housing part.Type: GrantFiled: February 7, 2014Date of Patent: June 20, 2017Assignee: IHI CHARGING SYSTEMS INTERNATIONAL GMBHInventors: Hermann Burmester, Joachim Delitz
