ABSTRACT:
A throttle valve supplies a pressure substantially proportional to the throttle position established by the operator. The throttle pressure is used as a control signal in automatic transmissions to effect the timing of ratio interchanges. A detent sleeve is slidably disposed in the body of the valve and prevented from movement in one direction by a locking ring. The sleeve is slidably positioned on the manual plunger and urged against the locking ring by hydraulic pressure. The sleeve is disposed in a position to be engaged by the operator input when the full throttle or "detent throttle" position is reached. After abutment of the sleeve by the operator input, a step function increase in operator input force is necessary for further throttle movement. This informs the operator that a predetermined throttle position has been reached.
