The regulating valve has a valve housing (1) with a valve seat (2) arranged between a valve inlet space (9), which is under the admission pressure, and a valve outlet space (10). The inlet side of the valve seat (2) cooperates with an adjustable measuring diaphragm (11), and its outlet side cooperates with a valve cone (12) actuatable by an adjusting device (8) controlled by differential pressure. A piston-shaped or diaphragm-shaped adjusting member (7, 43), connected to the measuring diaphragm (11) and subjected to the admission pressure, is mounted in the adjusting device (8) in such a way that it adjusts the measuring diaphragm (11) within an admission-pressure range, only counter to the effect of a desired-value spring (6), according to the value of the admission pressure and to the spring force of the desired-value spring (6). <IMAGE> |
