WASTEGATE VALVE AND TURBOCHARGER HAVING SAME

摘要

Wastegate assemblies and turbocharger assemblies including the wastegate assemblies are described. The wastegate assemblies include a housing enclosing both an actuator and a valve. The valve is operatively coupled to the actuator and the housing terminates with a crush seal. The housing also includes a mounting member connectable to a turbocharger to place the crush seal in sealing engagement with a wastegate opening in the turbocharger. The turbocharger assemblies include a housing enclosing a turbine and a compressor wheel that are operatively coupled together on a common shaft that defines an axis of rotation, and have a wastegate assembly removably mounted to an outlet end of the housing proximate the turbine and extending therefrom in a direction away from the turbine and the compressor wheel. Here, the wastegate assembly has a longitudinal axis that is parallel to the axis of rotation.

主权项

1. A wastegate assembly comprising:
a housing enclosing an actuator operatively connected to a valve, the housing terminating in a crush seal and having a mounting member connectable to a turbocharger to place the crush seal in sealing engagement with a wastegate opening in the turbocharger; wherein the crush seal corrects for tolerance variations between at least the mounting member and a surface of the turbocharger to which the mounting member is mounted.
