发明名称 A CONSTANT GAS FLOW REGULATING DEVICE
摘要 <p>A constant gas flow regulating device includes an inlet chamber, an outlet chamber and a movable wall that delimits the inlet and outlet chambers from each other. The moveable wall carrics a body comprising an opening that permits communication between the inlet and outlet chambers. An elongate element extends centrally in the opening of the body in the moving direction of the wall. The opening within the body surrounds a portion of the elongate element. In a first position the opening in the movable wall is placed in the vicinity of a first end of the elongate element. The element has a sectional size that gradually increases from the first end to a second end thereof. The size of the opening in the movable wall is larger than the sectional size of the elongate element. A helical spring biases the movable wall towards a first position.</p>
