Abstract
The compressed-gas device for the life-saving services which can be activated by water, more especially the automatic separating coupling for parachutes, comprises a channel (9) and two detector chambers (10, 11) which, via openings (12, 13), are connected to the channel (9) and, via openings (14, 15), are connected to one respective opposite outer surface (16, 17) of the device. The cross-section of the outwardly directed openings (14, 15) is larger than that of the connection openings (12, 13) to the channel (9). Only when the measuring block (2) is completely immersed in water are three pairs of electrodes (18, 19; 20, 21; 22, 23) bridged by water so that a fuel-gas charge is ignited via an electric circuit (7) with the aid of an igniter (8) (FIG. 2).
