Abstract:
1. A valve having an inlet, an outlet, and a passageway therebetween, the valve comprising: a damper element pivotally arranged within the passageway, the damper element being pivotally movable between a first position in which fluid flow through the passageway is substantially unaffected by the damper element, and at least a second position in which fluid flow through the passageway is substantially reduced by the damper element; and a solenoid having a moveable operator, wherein the damper element is engaged with the moveable operator and in said first position when the solenoid is not actuated, and the damper element pivotally moves to said second position against a first adjustable stop when the solenoid is actuated; and a first spring for biasing the moveable operator towards engagement with a second stop that limits the movement of the movable operator towards the damper; and a second spring, which biases the damper element to engage the moveable operator for establishing said first position when the solenoid is not actuated, and which biases the damper element against the first adjustable stop to establish said second position when the solenoid is actuated.
