    A regulator for a damper assembly operable to control the flow of conditioned air through a supply duct. The regulator includes a pressure responsive member connected to the damper assembly to vary the position thereof within the supply duct in accordance with changes in the conditioned air supply pressure to maintain a substantially constant volume air flow downstream of the damper assembly irrespective of such changes. The regulator further includes control point setting means for obtaining the level of constant volume air flow including force generating elements acting in opposition to the pressure responsive member for providing a first force at a maximum level of constant volume air flow and for further providing a second force at lesser levels of constant volume air flow.

    The invention relates to ventilation and air conditioning and can be used to control the air flow of the supply ventilation system.
    Known regulator damper with a control mechanism for the control point / containing installed in the supply pipe of the air conditioning system damper and two springs [1J. 1
    A disadvantage of the known regulator is that it does not ensure the maintenance of an almost constant volume flow of air after the damper, regardless of the change in pressure; laziness to the flap.
    , The purpose of the invention is the maintenance of a practically constant volume flow of air after the damper, regardless of the change in pressure to the damper. 2
    This object is achieved in that a regulator valve mecha | IOM regulatory checkpoint containing installed in the supply line system 2 konditsioniro- Bani damper and two springs is provided with a pressure sensitive valve and connected to a diaphragm or bladder attached to the last rotatable element, three rods, the first 30 of which is rigidly connected to the rotary element and pivotally with one end of the second rod, while the latter is pivotally connected to the other end with the third, pivotally connected to its 35 alternating with the other end wall of the supply pipe ,, and a lever connected at one end with a shutter in the middle part first, and by a spring with the second link, etc. wherein the springs have different degrees of initial tension.
    The drawing shows a regulator, a cross section.
    The damper regulator with the control mechanism for the control point 45 contains a damper 2 and two springs 3 and * 4 installed in the supply pipe 1 of the air conditioning system, and the regulator is equipped with a pressure bubble 5 connected to the damper 2 and attached to the damper 2 by a rotary element b, three rods 7 - 9, and the rod 7 is rigidly connected to the rotary element 6 and pivotally with one end 55 of the rod 8, while the rod 8 with the other end is pivotally connected to the rod 9, pivotally connected in turn with the other end to the wall of the pipeline 1 and the lever 10 connected at one end to the shutter 2 in the middle portion 7 with thrust, while using the springs 3 and 4 with a thrust '8, wherein the springs 3 and 4 have different degrees of initial tension.
    The damper regulator operates as follows.
    When working, when you want to get the maximum level of air flow of constant volume passing through the pipe 1, the spring 3 acts on the rod 7, which in turn acts on the rotary element b, the latter rotates the valve 2 in a counterclockwise direction, opening the passage section of the pipe 1 . By increasing the pressure of the supplied air to fill the bubble 5, the shutter 2 is rotated clockwise. In this case, the spring 3 under the action of the lever 10 is stretched and using the rod 7 and the rotary element 6, the damper 2 blocks the cross-section of the pipeline 1. The rod 8 is rotated, and the spring 4, creating a restraining force, acts on the damper 2 together with the spring 3. *
    At a minimum flow pressure in the pipeline 1, the shutter 2 closes the bore of the pipe 1. As the pressure increases, the bubble 5 is filled and thereby causes the shutter 2 to rotate under the action of the lever 10 clockwise, while the springs 3 and 4 are stretched and hold the shutter 2 in closed position.
    At the maximum value of the flow passing through the pipeline 1, the spring 3 creates a restraining force by acting on the valve 2 and controlling its movement depending on the filling of the bubble 5. in order to maintain a certain constant volume. The force created by the spring 3 increases as the shutter 2 rotates clockwise, as a result of which the spring 3 stretches.
    At low levels of flow in the pipe 1, the spring 4 creates an additional force to the force exerted by the spring 3. By creating an additional restraining force, the rotational movement of the shutter 2 decreases when the pressure of the supplied air into the bubble 5 changes.
    Thus, the use of the proposed regulator ensures the maintenance of a constant volume flow of air after the damper, regardless of the pressure change to the damper.
