| 20120037825 | ACTUATOR AND EXHAUST GAS RECIRCULATION VALVE, WASTEGATE OR VARIABLE TURBINE GEOMETRY DEVICE OF A TURBOCHARGER COMPRISING AN ACTUATOR - An actuator comprising a drive, at least one rotatable threaded element and at least one output element driven in translation thereby is described, characterized in that the threaded element has at least two regions of differing pitch and a rotational axis of the threaded element is inclined relative to a translational axis of the output element. | 02-16-2012 |
| 20120036950 | ACTUATOR FOR A WASTEGATE OR A VARIABLE TURBINE GEOMETRY DEVICE AND METHOD OF ACTUATION - An actuator has a rotary drive and a threaded element for converting the rotary motion of the rotary drive into a reciprocating motion of a tappet connected to a hinged wastegate and/or to a variable turbine geometry device of an exhaust gas turbocharger. The tappet and/or an axle between the tappet and the threaded element is received in at least one guide comprising at least one web and allowing for at least a slight tilting or pivoting movement of the tappet in at least one direction. At least some play is present between the web and at least one broadened portion on the tappet and/or on the axle. Methods of actuating a wastegate and/or a variable turbine geometry device. | 02-16-2012 |
| 20100176325 | EXHAUST GAS RECIRCULATION VALVE - An exhaust gas recirculation valve comprises a drive, at least one rotatable drive element and at least one translationally drivable driven element. The drive element comprises a thread element that is configured to convert rotational motion of the drive element into translation of the driven element. A rotational axis of the drive element is inclined with respect to a translational axis of the driven element. | 07-15-2010 |
