摘要： The specification describes a flow regulator for ducts in the case of which the free cross-section of the duct is arranged to be varied by a flap which can be turned against spring force by the flow in the closing direction. The flap is angled adjacent to the shaft and its one limb in the open position is directed substantially parallel to the axis of the duct to the rear and its other limb is directed in the closed position substantially perpendicularly to the duct axis. The spring force is adapted to act from the direction of the wall of the duct on a lever arm attached to the shaft in such a manner that the point of action of the force on rotation of the flap out of the open position into the closed position describes a circular arc, which are at the beginning is more oblique to the direction of the spring force than at the end.

摘要： An air distribution unit for discharging conditioned air into an area to be treated, including a variable volume control chamber regulating the volume of conditioned air supplied to the area. A control valve is operable to regulate the variable volume control chamber to maintain a substantially constant discharge of conditioned air into the area, irrespective of changes in supply air pressure. The control valve includes a first orifice for passage of a minimum quantity of control air through said valve to the control chamber. A bleed thermostat associated with the control valve regulated the quantity of control air supplied to the variable volume control chamber through the valve in response to area temperature.

摘要： 1,072,505. Ventilators. CONNOR ENGINEERING CORPORATION. June 25, 1964 [Dec. 4, 1963], No. 26397/64. Heading F4V. A device for controlling flow of conditioned air from a plenum to a room comprises a pair of dampers operated by the pressure of air flowing over them and a further manually controlled air flow throttling device. As illustrated, the manual device comprises two slotted troughshaped casing members 5 and 8, the former being fixed and the latter movable by a screw 51 to form a hit-and-miss damper. The member 8 is held in place by a coil spring 20. The air flow controlled dampers comprise flaps 33 and 34 pivoted on rods 31 and 32 secured to end walls of the casing. The flaps are pivotally connected by pairs of links to a block 39 slidable on a threaded rod 40 under the action of air flow pressure against a spring 44. The effect of the spring is adjusted by turning the rod 40 in a fixed threaded boss 41. In another embodiment, Fig. 4 (not shown), the hit-andmiss damper arrangement is replaced by pivoted casing members (54 and 55) which are adjusted against the action of springs (58) by turning a rod (59) around which is wrapped a wire (60).

摘要： 962,460. Fluid-pressure servomotor control systems. GARRETT CORPORATION. Aug. 2, 1960 [Aug. 3, 1959], No. 26809/60. Heading G3P. [Also in Division F2] At least two valves 14, 20 are provided to control the flow of air from a chamber 10, fed by a pump 11, such that the flow through the valves are maintained in a predetermined porportion. Each valve comprises a closure member 27 which is clamped to a diaphragm 32 forming chambers 35, 36 which receive a preselected pressure through conduits 84. The preselected pressure is provided by a controller 66 providing a preselected pressure loading on diaphragm 59 of valves 54, 55. The diaphragm 59 actuate valves 80 which control the leak of fluid from chambers 61, fed from the chamber 10 through ports 77, to provide the preselected pressure in the conduits 84. The flow through the valves 14, 20 are measured by venturis 124, 127 which provide a proportion pressure in conduits 123, 126 lending to a differential pressure controller 110. This controller comprises a housing divided into three chambers 111, 112, 113 by diaphragms 115, 119 connected to a member 147. The chamber 112 is connected to the chamber 10 while the chambers 111,113 receive the flow responsive pressures from conduits 123, 126. Variations in the flow proportion through the valves 14,20 actuate the diaphragms 115, 119 to control valves 133,141 which control the leak - age from the chambers 36, 35 through conduits 134,142 thus adjusting the valves 14, 20 in the opposite sense to maintain the predetermined proportion. This proportion is set by the adjustment of a spring loading 137. In a modification only one control valve, such as 133, is provided and the flow responsive pressures not on either side of a diaphragm to actuate this valve which controls the pressure in one of the chambers, such as 36. Thus the valve 20 only is adjusted to maintain the predetermined flow proportion.

摘要： A fluid flow device that can accurately and inexpensively measure a flow of a fluid can be implemented in a fan-powered unit, comprising a fan or other fluid-moving device. By accurately measuring the flow of the fluid to the fan, insights or efficiencies can be determined regarding operation of a larger system such as a heating, ventilation, and air conditioning (HVAC) system or other system. For instance, various procedures, including measuring, controlling, balancing, maintenance, prediction, or calibration procedures can leverage differential pressure measurement and/or the determined flow to the fan. As an example, current settings of the fan can be compared to historical fan settings to identify changes in fan load for a given fluid flow demand. Such can indicate changes in downstream or upstream devices, which can be used to indicate a device requires maintenance or another indicator.
