摘要： According to the present invention a damper for controlling the flow of conditioned air supplied through a supply duct to a conditioned space is provided. The damper includes a support housing which defines a flow passage which communicates the supply duct with the conditioned space. A plurality of damper blades are mounted within the support housing for pivotal movement about respective spaced apart parallel axes. A blade link interconnects the damper blades in a ganged relation so that a common pivoted orientation of the damper blades is determined by the position of the blade link. Means are provided for selectively exerting a force on the blade link which will either move the link toward the second position to increase the flow of air through the damper or for exerting a force on the blade link to move the link toward the first position to decrease the flow of air through the damper. Means are provided which allows the blade link to move toward the second position (maximum flow) in response to a force imparted on the damper blades by a build-up of pressure in the supply duct. Under such circumstances the force imparted upon the damper blades is sufficient to overcome the force exerted on the blade link to move the link toward said first position (flow substantially blocked).
摘要翻译：根据本发明，提供了一种用于控制通过供应管道供应到调节空间的调节空气流的阻尼器。阻尼器包括支撑壳体，其限定使供应管道与调节空间连通的流动通道。多个阻尼器叶片安装在支撑壳体内以围绕相应的间隔开的平行轴线枢转运动。叶片连杆以联合关系将阻尼器叶片互连，使得风门叶片的共同枢转方向由叶片连杆的位置决定。提供了用于选择性地在叶片连杆上施加力的装置，其将使链节朝向第二位置移动，以增加通过阻尼器的空气流，或者用于在叶片连杆上施加力以使连杆朝向第一位置移动以减小空气流过阻尼器。提供了一种装置，其允许叶片连杆响应于通过供应管道中的压力增加施加在阻尼器叶片上的力而朝向第二位置（最大流量）移动。在这种情况下，施加在阻尼器叶片上的力足以克服施加在叶片连杆上的力以将连杆移向所述第一位置（流动基本上被阻挡）。

摘要： A valve chamber which communicates through flue openings with bottom flues has therein a pair of dosing frames, each mounted on a pivot and movable thereby between a closed position against the openings and an open position withdrawn from the openings. Each pivot is attached to one end of an elongated eccentric member to the other end of which is attached a spring which urges the respective dosing frame to the closed or open position thereof. One or two pull rods are attached to the eccentrics to sequentially move the closed dosing frame away from the openings to the open position thereof, and to then move the open dosing frame to the openings to the closed position thereof.

摘要： A method of controlling indoor air humidity includes determining a dew point set point and determining a dew point of air from a space within a building. The method also includes, in response to determining that the dew point satisfies the dew point set point, determining a vent air dew point of air in an external environment surrounding the building. The method further includes, in response to determining that the vent air dew point is below the dew point set point by a dew point threshold, controlling a connecting member of a damper assembly to position a first damper of the damper assembly in an open position to draw in vent air from the external environment into the space, and to position a second damper of the damper assembly in a close position to substantially prevent recirculation of air through the dehumidifier.

摘要： The present invention provides a valve that controls a flow of gas or solid objects through a pipe, and particularly a z-valve used in an elevated rail transportation system. The valve includes vanes hinged to a valve stem that fold into a z-shape and retract into the valve body when the valve is open. A valve cap positioned at the top of the valve stem matches the contour of the inner surface of the pipe, allowing unobstructed flow. When the valve is closed, the valve stem is elevated into the interior of the pipe and the valve cap rotates 90° to match the contour at the top, providing a seal. The vanes extend from the z-shape to completely block a cross-section of the pipe, stopping the flow. The flow may be modulated by varying the extension of the vanes to allow a portion of the flow to pass the valve.

摘要： A novel fire, smoke and air control damper is disclosed wherein one or more hook-shaped hinge portions formed intermediate between the longitudinal edges of each damper blade engage complementally configured hook-shaped hinge elements formed on opposite sides of the damper frame. Formed on each of the ends of each damper blade are additional hook-shaped sealing portions which are adapted to mate with the hook-shaped sealing portions of adjacent blades in the closed position in order to form a double seal. A "dead" air chamber is formed between contiguous portions of adjacent blades when those blades are in the closed position. As the blades are slightly displaced towards the open position, a seal is nonetheless maintained between the blades due to the configuration of the sealing portions thereof. As the blades are further displaced, a serpentine air path is formed having a maximum fluid frictional resistance, which resistance is further amplified by the provision of a spoiler disposed adjacent to the tip of each hook-shaped sealing portion of each blade. Finally, the blades are movable to any of a variety of open positions so that volume control is easily effectuated.In the closed position, various blade portions also engage opposite sides of an inwardly depending flange in said frame to form a seal therebetween, thereby providing a positive pressure resistant seal.
摘要翻译：公开了一种新型的防火，烟气和空气调节阻尼器，其中形成在每个阻尼器叶片的纵向边缘之间的中间的一个或多个钩形铰链部分接合形成在阻尼器框架的相对侧上的互补配置的钩状铰链元件。在每个阻尼器叶片的每个端部上形成有附加的钩形密封部分，其适于在闭合位置与相邻叶片的钩形密封部分配合，以形成双重密封。当这些叶片处于关闭位置时，在相邻叶片的相邻部分之间形成“死气”气室。由于叶片稍微朝向打开位置移动，因此由于其密封部分的构造，密封件仍然保持在叶片之间。当叶片进一步移动时，形成具有最大流体摩擦阻力的蛇形空气路径，该阻力通过设置邻近每个叶片的每个钩状密封部分的尖端设置的扰流板进一步放大。最后，刀片可以移动到各种打开位置中的任一个，从而容易实现音量控制。

摘要： A fluid-flow apparatus having a damper frame provided with walls forming separate side-by-side flow paths for hot, cold and bypass air. Damper elements are pivotally mounted on shafts and arranged in the flow paths for blocking and unblocking same. Each shaft has a pinion gear mounted thereon for pivotal movement with the shaft and associated damper element. Rack gear segments are provided on a longitudinally slidably mounted carrier bar for engaging the pinion gears in a predetermined sequence which places in a blocked position one of the hot and cold air flow paths whenever the other flow path of that pair is simultaneously in an unblocked position. The bypass air flow path is unblocked when either the hot or cold air flow path is only partially unblocked. Spring or cam elements cooperate with flats on the damper element shaft for releasably retaining them in preselected positions.
