  • Compressor wheel assembly for turbochargers
    Patent number: 6164931
    Abstract: Turbochargers experience tensile loads due their high rotational speeds. These tensile loads tend to expand surface defects present about a bore portion of a compressor wheel. Expansion of these surface defects may ultimately result in failure of the compressor wheel. Removing these surface defects or imparting residual compressive stresses on the bore portion reduces failure of the compressor wheel caused by tensile loading.

  • Interference connection between a fluid line and a fluid injector
    Patent number: 4765543
    Abstract: Conventional joints between a fluid line and a body of a fluid injector are typically threaded or brazed. Such threaded joints are sometimes too bulky for certain engine compartments of limited space and such brazed joints are sometimes difficult to make with repeatable high quality.The present invention provides a relatively compact and inexpensive sealed joint for a fluid injector which includes a housing, a body, and a fluid line. The sealed joint is solely formed by an interference fit directly between an end portion of the fluid line and both the housing and an end portion of the body.
