Abstract: The invention provides a heat accumulator (1) for vaporizing fog liquid in a fog generator, the heat accumulator comprising multiple closely contiguous, parallel oriented rods (2) with a diameter of between 0.2 mm and 15 mm.

Abstract: The present invention relates to a fog-generating device comprising a reagent (1), ignition means (2), a reservoir (3) containing a fog-generating material (4), and a heat exchanger wherein gas generated by ignition of the reagent (1) drives fog-generating material from said reservoir to said heat exchanger. Further it relates to a removable housing for a fog-generating device comprising a reagent and a reservoir containing a fog-generating material, wherein in that said removable housing further comprises means to allow transmission of an ignition signal from said fog-generating device to said reagent. The invention further provides the use of said device and/or removable housing for the generation of fog, in particular to protect against intruders and physical treat by persons. In a particular embodiment, the fog-generating device of the present invention or the removable housing therefore comprises depressurizing means (18).

Abstract: The current invention provides for a fog generator. More specifically, it provides for a housing comprising a fog generating liquid and a valve that, in a closed position, prevents the fog generating liquid from flowing out of the housing, in which the said valve is kept in a closed position by means of a fuse wire (6).

Abstract: The present invention is directed to a fog generator comprising a vessel that contains a fog generating fluid, driving means for driving the fluid from the vessel into a heat exchanger which transforms the fog generating fluid into steam and is connected with the vessel, a means for ejecting the steam in the form of a fog and connected to the heat exchanger, a valve for switching on and off the fluid flow from the vessel into the heat exchanger, and a means for purging non-ejected steam out of the heat exchanger into the ambient connected to the means for driving the fluid, characterized in that the means for driving the fluid and the means for purging are connected such that by switching off the fluid flow non-ejected steam can be purged out of the heat exchanger

Abstract: The present invention is directed to a fog generator comprising a vessel that contains a fog generating fluid and a compressed propellant gas for driving the fog generating fluid from the vessel into a heat exchanger which transforms the fog generating fluid into steam and is connected with the vessel, and a valve positioned between the vessel and the heat exchanger, characterized in that the valve is adapted for controlling the fog generating fluid flow rate by varying its orifice resistance as a function of vessel pressure, such that the fluid flow rate is independent of vessel pressure.
