  • Power deflator mechanism for scuba buoyancy vests
    Patent number: 4045835
    Abstract: A power deflator for a buoyancy vest includes a Venturi tube attached to the vest fitting. A mouthpiece control unit has an actuator movable in a path. Initial movement opens a conduit for slow deflection powered by ambient pressure. Continued movement of the actuator sends pressurized air through the Venturi tube for faster deflation of the vest.
