Stephen T. Konwinski has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Partially plastic fuel injector component and method of making the same
    Patent number: 6631857
    Abstract: Use of pump and line fuel injectors has become more common in fuel injection systems. While these fuel injectors do not typically include individual electrical actuators or fuel pressurization means, they still include a number of components that must be intricately machined in order for the fuel injector to perform as desired. The present invention is directed to reducing the number of machining steps, and therefore the cost, of producing such a fuel injector by utilizing a plastic component that can allow for a reliable and cost effective replacement of more intricately machined fuel injector components.
