Controller for gaseous medium e.g. oxygen, has intermediate connection in transition region of discharge passage and outlet below diaphragm, and comprised of variable cross-section connecting channel to diaphragm chamber
摘要
<p>The controller (1) has a spindle drive for continuous change and adjustment of operating pressure at an outlet (15) by actuation along with a diaphragm (6). A transmission link (9) transmits manipulated variable of the operating pressure to valve tappet (18) of control insert (10). A discharge channel (23) is provided with an opening width smaller than that of the outlet. An intermediate connection (27) is formed in the transition region of discharge passage and outlet, below diaphragm and comprised of variable cross-section connecting channel (29) to a diaphragm chamber (32).</p>
