Gary W. Kotchi 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).

  • Injection molded throttle body
    Patent number: 6491020
    Abstract: The subject invention is a throttle body for an intake manifold of a spark ignition internal combustion engine. The throttle body includes a throttle plate member comprising a shaft, a throttle plate and a lever. The throttle plate member is integrally molded as one piece from an engineering resin. The throttle body also includes an air intake portion and an air discharge portion. Either the air intake or the air discharge portions may be integrally attached to the intake manifold prior to assembly of the throttle plate member.
    Type: Grant
    Filed: October 22, 2001
    Date of Patent: December 10, 2002
    Assignee: BorgWarner Inc.

  • Fail safe throttle positioning system
    Patent number: 5429090
    Abstract: A fail-safe throttle positioning device is disclosed for an engine induction system. A throttle body is provided having a fluid passage. A movable throttle valve is disposed within the fluid passage for at least idle speed control. An actuator mechanism is connected to the throttle valve for operably moving the throttle valve between a minimum fluid flow position and a maximum fluid flow position. A fail-safe mechanism urges the throttle valve toward an intermediate position between the minimum and maximum fluid flow positions to prevent inoperability of the engine during failure of the actuator mechanism.
