FIELD: manufacturing technology.
SUBSTANCE: invention relates to a heat trigger element (1) having vessel body (1) having outer wall (7) made of a cracking material and cavity (2) enclosed by outer wall (7) lying inside vessel body (1), in which triggering liquid is enclosed, wherein this body (1) of the vessel is elongated along the axial direction and has an axially extending tubular mid section (8) and two end sections (3, 4) located on each of the axial ends, in which cavity (2) is closed by some kind of plug. In order to reliably protect such heat trigger element (1) from damage caused by bumps, and not only before installation, but also in a situation of use, in which it is built into a valve structural element or the like, it is proposed that trigger element (1) has intensifying cracking material in relation to impact loads acting across longitudinal direction, long-acting reinforcement (9).
EFFECT: thermal triggering element is described.
