20100098532 | COMPRESSOR HOUSING - A compressor section ( | 04-22-2010 |
20100104424 | VARIABLE TURBINE GEOMETRY TURBOCHARGER - A turbocharger is provided having a turbine wheel ( | 04-29-2010 |
20100202877 | TURBOCHARGER DIFFUSER - A housing ( | 08-12-2010 |
20110173974 | VARIABLE FLOW WASTEGATE - A wastegate for a turbocharger wherein the valve is provided with a horn to provide a more progressive, optimally near linear, curve of turbocharger boost-to-valve opening than possible with the typical flat wastegate valve. The addition of a three-dimensional horn in the flow path is a far more cost-effective solution to acquire linear flow than an approach involving very finite, accurate control of the valve position. | 07-21-2011 |
20120036849 | SIMPLIFIED VARIABLE GEOMETRY TURBOCHARGER WITH VARIABLE FLOW VOLUMES - A variable geometry turbocharger is simplified yet able to maintain pulse energy. In a first embodiment, a turbine housing is provided with a pivoting wall which pivots about a point near the entry to the turbine housing. By moving the wall about the pivot point, the effective volume of the turbine housing volute is varied, thus effectively reducing the volume of exhaust gas in the volute, allowing control of exhaust gas flowing to the turbine wheel. In the second embodiment of the invention, a rotating wedge segment within the volute is rotated from a first position to a second position, changing the effective volume of the volute and allowing control of exhaust gas flowing to the turbine wheel. | 02-16-2012 |
20130152582 | COMPRESSOR RECIRCULATION INTO ANNULAR VOLUME - To solve the problems of compressor wheel blade flow separation causing surge type noises when a compressor return or recirculation valve is opened or closed, bypass airflow from a compressor recirculation valve is fed into an annular volume, defined between inner and outer walls or shaped as a radially expanded, axially flattened cylindrical space in the compressor inlet, so that the generally unidirectional radial flow from the compressor recirculation valve is re-directed and organized as it is turned from generally radial to generally axial, merging with the general inlet flow and presenting the compressor wheel with airflow of “circumferentially uniform” flow velocity. | 06-20-2013 |
20130219885 | SIMPLIFIED VARIABLE GEOMETRY TURBOCHARGER WITH INCREASED FLOW RANGE - A variable geometry turbocharger is simplified yet able to maintain pulse energy. In a first embodiment, a turbine housing is provided with a pivoting flow control valve which pivots about a point near the entry to the turbine housing. By moving the valve about the pivot point, the effective volume of the turbine housing volute is varied, thus effectively reducing the volume of exhaust gas in the volute, allowing control of exhaust gas flowing to the turbine wheel. In the second embodiment of the invention, a rotating wedge segment within the volute is rotated from a first position to a second position, changing the effective volume of the volute and allowing control of exhaust gas flowing to the turbine wheel. | 08-29-2013 |
