The two pressure regulators (4,5), one near the cut-off valve (2) and the other near the breathing mask (6) are connected (3). A movement detector (17) is also provided with an activation device. Components (10,8,7,18) transmits pressure changes in the connection to the activation device (26) of the movement detector. The movement detector is activated when the pressure change has increased. - The components have pressure sensors (10) in the connection, which transmits monitored pressure changes to the activating device of the movement detector. The components have a conduit which is in fluid contact with the gas in the connection in front of the second pressure regulator (5). The other end of the conduit is connected to the movement detector activation device. |
