ABSTRACT:
In a transmission having input and output shafts drivingly connected by fluid pressure operated ratio establishing devices an improved centrifugally actuated valve is provided to disestablish the driving connection maximum angular velocity of the input shaft. The valve includes a sphere disposed in a stepped bore which sphere is spring biased to a closed position for normal operation and which shifts in response to centrifugal force to an open position in a fluid flow path thereby exhausting the drive establishing device and also being flushed of any contaminants.
