Abstract (en)
[origin: EP1253326A2] The valve has a setting throttle (2) with a transverse aperture (14) across the main connecting line (13), in which a control element can move reciprocally against an elastic counter-force (15). This element has a control aperture, and is subject to the gas pressures on either side of the valve membrane, so that the aperture cross section depends on the pressure difference before and after the valve.
