Patent number: 11378003Abstract: A compressor for a supercharging device of an internal combustion engine and a supercharging device are described. The compressor has an iris diaphragm mechanism that has a special drive. The drive includes an adjusting ring as an integral constituent part of an actuator of the drive and is formed as a rotor, which surrounds an air supply channel, of an electric motor. This results in a significantly simplified structural form of the drive.Type: GrantFiled: December 16, 2020Date of Patent: July 5, 2022Assignee: Vitesco Technologies Germany GmbHInventors: Mathias Bogner, Hartmut Claus

Patent number: 7600380Abstract: The present invention provides a two-stage turbocharger unit having a valve that will help to create a smooth transition of exhaust gas energy from the high-pressure turbine (HP) turbine to the low-pressure (LP) turbine. The LP and HP turbines are positioned such that the valve can be in one position to force all of the exhaust gas to flow through the HP turbine and when in another position to force all of the exhaust gas through the LP turbine. When the valve is placed in an intermediate position, the exhaust gas can be variably directed to flow through both turbines, with the percentage of exhaust gas flowing through each turbine being dependent on the position of the valve.Type: GrantFiled: May 10, 2005Date of Patent: October 13, 2009Assignee: BorgWarner Inc.Inventors: Thomas A. Grissom, Hartmut Claus

Patent number: 7089737Abstract: A housing for a turbocharger comprises a housing shell which surrounds, at least partially, a rotor space, at least one manifold of a combustion engine, a pipe for connecting the housing shell with at least one manifold of the combustion engine, and a cylinder head of said combustion engine. All these parts are integrally cast as one single piece. This may be effected by a method which comprises the steps of: joining and bonding sand cores for part of a housing shell of the turbocharger with sand cores for shaping the cavities of the manifold, and these, in turn, with sand cores for shaping the cylinder head. Subsequently, inserting said joint and bonded sand cores into respective firmly interconnected molds for molding said part of a housing shell of said turbocharger, for said manifold and said cylinder head, and filling molten metal into said molds and allowing solidification of said metal.Type: GrantFiled: November 29, 2004Date of Patent: August 15, 2006Assignee: BorgWarner, Inc.Inventor: Hartmut Claus

Publication number: 20050019158Abstract: A twin flow turbine housing for two intake channels (13a, 14a) separated from one another in terms of fluid technology and intended for a fluid which is to be fed under pressure to a turbine, for example of a turbocharger, consists of two substantially symmetrical half-shells (13, 14) which between them enclose a substantially flat partition (18). The two half-shells (13, 14) and the partition (18) consist of sheet metal and are welded to one another. The outer contours of the half-shells have bent-over edges (20, 20?) and notches (30?) which are engaged by extensions (30) of the partition (18), the extensions (30) projecting outwards through the notches (30?) to enable them, after assembly of the half-shells, to be welded to the edges thereof. This manufacturing technology can be used for uncontrolled turbochargers and also for turbochargers controlled by a bypass.Type: ApplicationFiled: July 23, 2004Publication date: January 27, 2005Inventors: Hartmut Claus, Michael Mayer
