  • Electronic throttle return mechanism with a two-spring and one lever default mechanism
    Patent number: 6286481
    Abstract: An electronic throttle control system having a housing 22 with a motor 40, throttle valve 60, gear mechanism 100, and failsafe mechanism. A main spring member 130 positioned between the housing 22 and a gear mechanism 104, which in turn is attached to the throttle valve shaft 62, biases the throttle plate 60 towards the closed position. A spring-biased default mechanism 132, 134 biases the throttle plate 60 from its closed position to a default or “limp-home” position.
    Type: Grant

  • Electronic throttle control system with two-spring failsafe mechanism
    Patent number: 6173939
    Abstract: An electronic throttle control system having a housing 22 with a motor 40, throttle valve 60, gear mechanism 100, and failsafe mechanism 130. A spring member 150 attached between the housing 22 and a gear member 104 attached to the throttle valve shaft 62 biases the throttle plate 60 towards the closed position. A spring-biased plunger member 134 biases the throttle plate 60 from its closed position to a default or “limp-home” position.
