Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A wastegate assembly for a turbocharger comprising: a housing enclosing an actuator operatively connected to a wastegate valve, the housing terminating in a crush seal at an end of the housing; and at least one mounting member connectable to a mounting surface of the turbocharger to place the crush seal in sealing engagement against a surface of the turbocharger defining a wastegate opening in the turbocharger; and wherein the wastegate valve includes an…
