  • Exhaust ventilator
    Patent number: 10690375
    Abstract: A ventilator for exhausting gas from an exhaust port, by utilizing wind or relative wind around and through the ventilator to create a reduced pressure zone at an open exhaust port. Tapered intermediate portions extend from the opposite ends of a centrally located throat portion within a body of the ventilator to a pair of opposite mouths through which gas can flow out through the ventilator from the exhaust port. Each mouth of the ventilator has an opening with an area significantly larger than the area of a flow path within the throat portion. The throat portion may be of constant internal cross-sectional area over its entire length.

  • OMNIDIRECTIONAL VENT CAP
    Publication number: 20130045669
    Abstract: An omnidirectional vent cap for venting holding tanks is provided. By providing a 360 degree venturi channel, the present invention can use a small movement of air to reduce the air pressure above the exhaust port to draw out vapors or gasses. Since the device is symmetrical about the central axis the movement of air can be from any direction relative to the device.
