Throttle modulator

DETAILED DESCRIPTION An object of this invention is to provide a mechanism for controlling fuel delivery to a prime mover independent of throttle pedal position during shifting of a transmission driven by the prime mover.
Another object of this invention is to provide such a mechanism for controlling shifting shocks.
Another object of this invention is to provide such a mechanism for effecting synchronism in an automatic mechanical transmission.
According to a feature of the invention, the mechanism of the present invention is adapted to be interposed between an engine throttle pedal and an engine fuel control device such as a throttle valve or a fuel injection device.
The mechanism comprises moveable means including a first portion adapted for movement in response to movement of the throttle pedal, a second portion adapted to be connected with the fuel control device for slaved movement therewith, and a third portion; and actuator means for moving the third portion of the moveable means such that the second portion moves to vary the fuel control delivery independent of throttle pedal position during shifting modes of the transmission.
According to another feature of the invention the mechanism, as adapted in the previous feature, including a rigid member having a first portion at one end adapted for movement between fuel increasing and decreasing positions by the throttle pedal, a second portion disposed between the ends of the member and slaved for movement with the fuel control device, and a third portion at the other end of the member mounted for pivotal movement on an actuator operative to move the third portion between first and second positions.
