Transmission throttle valve system

摘要

An automatic power transmission control system having a throttle valve adapted to be connected mechanically through a linkage to the adjustable engine carburetor throttle valve in an automotive vehicle driveline wherein provision is made, in the event of a failure of a mechanical linkage, for an increase in the effective throttle pressure signal made available to the control valve elements of the transmission system thereby assuring that the transmission clutches and brakes will have sufficient control pressure to maintain torque transmitting capacity for both torque delivery to the traction wheels as well as during engine braking of the vehicle at high speeds.
