ABSTRACT:
A speed-sensitive device comprises a cylinder mounted on a shaft and rotatable therewith. The cylinder contains liquid that is pushed by the action of centrifugal force against a piston, the piston being connected to engage a clutch when the shaft speed reaches a predetermined minimum value. A speed-sensitive valve opens a bore connecting the opposite sides of the piston when the speed is above a minimum value to prevent a vacuum affecting the operation. The principal application is to a fluid coupling and the device operates a mechanical clutch that "locks up" the fluid coupling above the predetermined speed to prevent slip losses therein.
