Abstract
An improved ball controlled float control unit wherein a slotted raceway housing pivotally accomodates a narrow ball cage within the slot and with the ball cage being in constant contact with said ball while the ball is permitted to be rollingly supported by the edges defining the slot, with the ball being precluded from getting out of or behind the ball cage, thereby eliminating any possibility of the ball locking up the control function of the unit.
