    • A metallic air admittance valve has a tubular body with a valve chamber integral to one end of the tubular body. The valve chamber has a valve and an air inlet configured to permit the flow of air when the pressure within the valve is less than the pressure outside of the valve, but to prevent the flow of air when the pressure within the valve equals or exceeds the pressure outside of the valve. The tubular body and valve chamber are fabricated from metal and, therefore, do not emit noxious or toxic fumes when subjected to fire. Plumbing systems in commercial buildings may have metallic air admittance valves located within the plenum area of the building without presenting the risk of the distribution of toxic fumes throughout the building when the air admittance valve is subjected to fire.

    • A protective damper for controlling the flow of fluid through a ceiling diffuser has a frame defining an opening through which the fluid flows. A barrier has a closed position which prevents the flow of fluid through the opening and an open position which allows fluid flow through the opening. The barrier is restricted to linear movement between the open and closed positions. A spring is operably coupled with a shaft and exerts a bias on the shaft tending to rotate the shaft on its longitudinal axis in one direction. An actuator is operably coupled with the shaft and rotates the shaft about its longitudinal axis in the opposite direction when the actuator is energized. An elongated rigid element is pivotally coupled with the shaft and with the barrier, respectively. The rigid element is for pulling the barrier by the shaft into the closed position when the shaft is rotated in the one direction and for pushing the barrier into the open position when the shaft is rotated by the actuator in the opposite direction.
    • 用于控制通过天花板扩散器的流体流动的保护阻尼器具有限定流体流过的开口的框架。 阻挡物具有闭合位置,其阻止流体流过开口和允许流体流过开口的打开位置。 屏障限于打开和关闭位置之间的线性运动。 弹簧与轴可操作地联接,并且在轴上施加偏压,倾向于使轴在其纵向轴线上沿一个方向旋转。 致动器与轴可操作地联接,并且当致动器通电时使轴围绕其纵向轴线在相反方向旋转。 细长的刚性元件分别与轴和屏障枢转地联接。 当轴沿一个方向旋转时,刚性元件用于将轴向阻挡件拉动到关闭位置,并且当轴由致动器沿相反方向旋转时,将挡板推入打开位置。

    • A closing device with a valve having a high speed reaction. A dome shaped valve is forced open by applying pressure to a piston which is attached to the dome. The opening pressure is provided by an electromagnetic jack and is transmitted through a lock which has a releasing threshhold. The displacement of the piston biases a return spring into a compressed state. Force applied to the lock by a solenoid counteracts the force of the return spring so as to keep the lock locked and thus keep the dome open. When enough force is applied to the dome so as to overcome the threshhold of the lock, or if the lock is intentionally released, the piston is freed and the return spring quickly forces the dome to a closed position.
    • 具有阀的闭合装置具有高速反应。 通过对附接到穹顶的活塞施加压力来迫使穹顶形阀打开。 打开压力由电磁千斤顶提供,并通过具有释放阈值的锁来传递。 活塞的位移将复位弹簧偏压到压缩状态。 通过螺线管施加到锁的力抵消了复位弹簧的力,以保持锁定,从而保持穹顶打开。 当足够的力施加到圆顶以克服锁的闸门时,或者如果有意地释放锁,则活塞被释放,并且复位弹簧快速迫使穹顶到关闭位置。
