Patents by Inventor Willy A. Fiedler

Willy A. Fiedler 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).

  • Fuel control and injection system for I.C. engines
    Patent number: 4265209
    Abstract: Intake air flowing through a controlling device turns a spring constrained rotor and an attached metering valve to control the fuel flow. The aerodynamically computed turn angle depends on air velocity and density and on vortices generated with vanes actuated with device-integral means responding to operational needs. The fuel is delivered to intake ports or to cylinders.
    Type: Grant
    Filed: January 19, 1979
    Date of Patent: May 5, 1981
    Inventor: Willy A. Fiedler
  • Fuel distribution in internal combustion engines
    Patent number: 4170205
    Abstract: In a low-pressure fuel control system increments of fuel and air flow from a vented receptacle sequentially into multiple fuel valves which are either actuated or responding to air pressure differentials and the latter can also be used for spark ignition.
    Type: Grant
    Filed: October 5, 1977
    Date of Patent: October 9, 1979
    Inventor: Willy A. Fiedler
  • Fuel control of internal combustion engines
    Patent number: 4068626
    Abstract: Vanes in an air duct, independently controlled, one by the engine operator and others by environmental factors, generate vortices determining the speed of a turbine and thereby the flow of fuel through a fuel meter and fuel valves into prechambers for vaporization and mixing with spiraling air.
