摘要： A control system for an HVAC system serving at least two zones, each zone receiving conditioned air by way of a zone duct, each zone duct including a zone damper having a first portion and second portion controlled by a actuator to move between an open and a closed position in response to a zone thermostat, a second portion responsive to the static pressure in a HVAC system to open and bleed an amount of conditioned air past the damper when the static pressure of the system increases above a selected level, and a weight adjustment for modifying the torque exerted by the second portion against the system static pressure to adjust the selected level.

摘要： A shutter device reduces resistance in an air passage while maintaining air-tightness, thus reducing a load to a fan and a motor. A shutter mount is provided between an intake port adapted to be connected with a side from which air enters and a discharging port adapted to be connected with a side from which air is discharged. A shutter frame is inserted into an inside of the shutter mount. A shutter for preventing outside air from entering from the discharging port is mounted to the shutter frame. The shutter mount has a rib thereof for sealing a gap produced between the shutter and the shutter mount when the shutter is closed. The rib has an inner diameter substantially equal to a diameter of the discharging port as seen from the discharging port

摘要： An arrangement for regulating the flow of a gaseous medium in a conduit includes a flap valve pivotably mounted in the conduit and biased by a spring toward its open position and by the pressure of the gaseous medium flowing through the conduit towards its closing position. A rod-shaped member is pivotally mounted on one section of the flap valve, and a sleeve-shaped member is pivotally mounted on a plate-shaped element rigid with the conduit and extending axially thereof downstream of the flap valve. The sleeve-shaped member has a passage therein in which the rod-shaped member is received with play so that, upon rapid movement of the rod-shaped member in the passage, the sleeve-shaped member is entrained by friction on pivots, thus seizing the rod-shaped member. In this manner, the flap valve is prevented from fluttering, while its responsiveness to gradual pressure changes of the gaseous medium is unaffected.

摘要： A ventilating damper assembly particularly adapted for use in conjunction with an evaporative cooler system for architectural structures includes a duct inserted into the ceilings of rooms cooled by the evaporative cooling system to discharge air from within the room through an attic space located above the ceiling and out into the atmosphere through vents in the attic. The ventilating damper assembly has a gravity-closed pivotally-mounted lid on the upper end of the duct to keep the duct closed whenever the evaporative cooling system is not in operation or whenever backdrafts from the attic occur. Positive air pressure within the room moves upwardly through the damper assembly, opening the lid to permit air to escape from the room into the attic, thereby maintaining the air flow necessary for efficient operation of an evaporative cooler and additionally exhausting the relatively cool air into the attic space above the ceiling to further improve the cooling efficiency of the system. Temperature sensitive normally-open self-closing anti-draft dampers close the duct whenever abnormally high temperatures occur.

摘要： The shaft for the flap of a fluid flow regulator extends through the tubular housing of the regulator and its end portions are received in thrust bearings which subject the shaft to axial stresses. The bearings have internally threaded sleeves which are bonded to the housing, externally threaded plastic plugs which mate with the respective sleeves and have sockets for the respective end portions of the shaft, and hard metallic balls in the innermost portions of the respective sockets. The flap has two mutually inclined sections at the opposite sides of the shaft and is biased to open position, in which one of its sections lies flush against a centrally located partition in the housing, by a helical spring whose characteristic can be changed from the outside of the housing.

摘要： A flow regulator for air ducting comprises a flap which can be rotated about a shaft against the action of a spring, by the air current, to regulate air flow therepast. The flap has two portions which are disposed at an obtuse angle to each other about a bend line, one of the portions, in an open condition of the regulator, being directed downstream of the shaft generally parallel to the ducting axis, and is obliquely oriented in the closed condition and the other portion, in a closed condition of the regulator, is disposed in a plane lying at right angles to the ducting axis, and is obliquely oriented in the open condition. The obtuse angle of the flap portions is preferably of the order of 145.degree. to 155.degree..
