  • Fluid flow controller
    Patent number: 4454768
    Abstract: A pivotal shaft is connected to an actuator with the actuator being pivotally mounted with one end extending into a conduit and the other end being pivotally connected to the shaft. Actuation of the actuator through fluid flow causes the shaft to pivot and, if desired, causes actuation of a switch.The pivotal shaft is carried in a housing which has an opening connected to an opening in the conduit. The actuator is pivotally mounted within the housing opening where a dam is provided to substantially prevent bypass of water through the housing around the actuator to provide better and more reliable actuation force.
