A release mechanism is provided for a fire protection sprinkler having a body, including an output orifice sealed with a seal cap. The body has two arms extending therefrom that meet at a hub having a preload mechanism. The release mechanism includes a lever having a first end mounted on the preload mechanism. The mechanism further includes a strut having a first end mounted on the seal cap and a second end mounted on the first end of the lever. A thermally-responsive element is mounted in a second end of the lever, opposite the first end, and the thermally-responsive element has a displaceable member extending therefrom, so as to contact the strut.

L'invention porte sur un mécanisme de déclenchement pour gicleur à incendie comprenant un corps ayant un orifice de sortie fermé hermétiquement par un capuchon d'étanchéité. Deux bras s'étendent depuis le corps pour se rejoindre sur un moyeu doté d'un mécanisme de précharge. Le mécanisme de déclenchement comprend un levier doté d'une première extrémité montée sur le mécanisme de précharge. Le mécanisme comporte également une entretoise ayant une extrémité montée sur le capuchon d'étanchéité et une seconde extrémité montée sur la première extrémité du levier. Un élément thermosensible est monté dans une deuxième extrémité du levier, face à la première extrémité, et l'élément thermosensible est doté d'un élément mobile partant dudit élément pour venir au contact de l'entretoise.
