Eine weitere Ausführungsform der Einrichtung ist in Fig. 2 dargestellt. Es wird hier das   Hilfsauslassventil   nicht von dem Rückschlagventil, sondern von einem Kolben oder einer Membrane betätigt, auf dessen bzw. deren beiden Seiten Drücke herrschen, deren Unterschied dem Quadrat der Abgabe des Ventilators oder Kompressors proportional ist. Zu diesem Zweck wird, wie Fig. 2 zeigt, der unterhalb des Kolbens 7 befindliche Raum des diesen Kolbon enthaltenden Zylinders mit einer Pitotschen Röhre   8   verbunden, die an irgendeiner Stelle der Rohrleitung 9 angeordnet ist, während der oberhalb des Kolbens befindliche Raum mit einem Rohr 10 in Verbindung steht, das unmittelbar, d. h. ohne jede Verlängerung, in ein Leitungsrohr 9 einmündet.

Another embodiment of the device is shown in FIG. Here the auxiliary outlet valve is not actuated by the check valve, but by a piston or a diaphragm, on whose or both sides there are pressures whose difference is proportional to the square of the output of the fan or compressor. For this purpose, as FIG. 2 shows, the space located below the piston 7 of the cylinder containing this piston is connected to a Pitot tube 8 which is arranged at any point in the pipeline 9, while the space located above the piston is connected to a tube 10 which is directly, i. H. without any extension, opens into a pipe 9.



     Both arrangements (Fig. 1 and 2) can also be combined with one another,
