<p>The invention relates to fire-fighting technology, and specifically to fire-extinguishing agents which can be applied automatically. The present invention is used for autonomously employing gas, powder and aerosol fire-extinguishing agents. A thermal mechanism for activating a fire-extinguishing generator includes, located in a housing, a hammer having a spring enveloping same, which spring loads the hammer in the direction of a capsule. The mechanism has a locking device which blocks the hammer from being displaced to a ready state, and has an initiating element, installed in a secondary housing, which holds the locking device in a ready state. The locking device is made up of a blocking bushing, which is located in the housing and which comes into contact with the hammer, and of a stopper, which comes into contact with a ready-state initiating element and which is installed so as to be capable of displacement at the junction of the housing and the secondary housing, partially entering each of said housings. The blocking bushing has petals which are made of a resilient material, and which enter a ready state when located in a gap between the housing and the stopper, and which exit the ready state when the initiating element is triggered. The spring is positioned within the blocking bushing. The invention provides for increased reliability when activating a fire-extinguishing generator.</p> |
