Abstract: A thermal triggering element for sprinklers, valves or the like including an enclosed compartment with a container filled with a highly temperature-sensitive shattering fluid for precise and reproducible adjustment of a triggering temperature within the range of a few degrees Celsius. The invention increases the accuracy of the triggering temperature and identifies shattering liquids that allow precise sensitive triggering action in terms of temperature of the triggering element and open up further triggering temperatures ranges. The triggering fluid contains or consists of a hydrocarbon compound selected among one of the following substance groups or a mixture thereof: d) a heterocyclic hydrocarbon having a OH, NH or NH2 group bonded to a carbon atom; e) a hydrocarbon having at least one benzene ring with an OH group bonded to one of the carbon atoms of the benzene ring; f) a phosphate with at least one hydrocarbon moiety.

Abstract: A thermal release element for valves in the form of a completely enclosed inner space with a container filled with a release liquid in which the release liquid contains a hydrocarbon selected from one of the following substance groups or containing a mixture of the hydrocarbons of an aliphatic bromide, a hydrocarbon with a nitro group, a singly halogenated benzene ring, and an aliphatic ester compound with two double-bonded oxygen atoms.
