    摘要： A vent termination assembly for a vertical pipe, stack or tube including a hinged flapper to normally close the end of said vent termination assembly and at least one downwardly sloping normally open to the atmosphere side pipe bevelled to discharge generally upward. The flapper contains energy adsorbing side beams to reduce velocity of the flapper during opening.

    摘要： A clothes dryer vent hood is fabricated of plastic by an injection molding process, and is provided with an integral rearwardly open annular portion for receiving a tubular member or pipe, which pipe is made of metal, and has several radially inwardly projecting tabs formed at the open end which is to be assembled with the annular portion of the vent hood. This annular portion is molded to define L-shaped grooves for receiving the tabs, and each groove has an abutment defined therein such that the hood can be assembled with the tubular member by axially joining these parts to move the tabs past these abutments in the grooves, followed by a twisting motion of the parts to further lock them together.

    摘要： An exhaust air hood has a tubular body and at least one plate member having a chamber inside thereof. The plate member has a planar configuration including widths gradually decreasing toward two longitudinal ends of the plate member, the chamber having an opening at each longitudinal end of the plate member. The exhaust air hood discussed is capable of reducing backflows through exhaust air ports caused by wind pressure, thus enabling a proper ventilation system to be achieved.

    摘要翻译： 排气罩具有管状体和至少一个在其内部具有室的板构件。 板构件具有包括朝向板构件的两个纵向端部逐渐减小的宽度的平面构造，该室在板构件的每个纵向端部具有开口。 所讨论的排气罩能够减少由风压引起的排气口的回流，从而实现适当的通风系统。
