  • Torsion spring assembly for electronic throttle
    Patent number: 6672280
    Abstract: An electronic throttle body uses a spring and an insert to generate a force tending to oppose the motion of opening a throttle. The insert locates and centers the coils of the spring and also acts during assembly to place the proper amount of torsion on the spring and the throttle body system. Once a throttle body motor or other force ceases to exert force against the spring, the spring causes the throttle to close.

  • Electronic throttle return spring assembly
    Patent number: 6364287
    Abstract: Disclosed herein is a throttle return spring assembly for use in an electronic throttle unit having a throat and a valve rotatably fixed within the throat to close and open the throat. The throttle return spring assembly includes a shaft extending along a rotation axis and connected to the valve for opening and closing the throat of the throttle. A return spring has a first leg connected to the shaft and a second leg extending axially into an opening of a guide. The guide allows rotation of the return spring about the rotation axis and restricts lateral translation of the return spring. The guide has an arcuate inner radial wall defining a catch projecting radially inward. The return spring is wound by rotating the second leg to follow the arcuate surface and engage the catch. A special winding tool having a radial slot which engages the second leg can be piloted about the end of the shaft to wind the return spring.
