<p>The device according to the invention comprises : a plunger tube (6), capable of being introduced into the tank down to the imposed maximum filling level; a cylindrical chamber (10) communicating with the inside of the plunger tube and emerging via an orifice into an expansion chamber (11) provided with a vent (20) for aeration; a cylindrical core (12), mounted so as to slide in the cylindrical chamber (10); at the external part of this core, at least one longitudinal groove (21), capable of making the inside of the tube (6) communicate with the expansion chamber (11); in this expansion chamber (11), an elastic return means (17), against which the core (12) moves; also, in this expansion chamber (11), a temperature-measuring probe (27); and means slaved to this probe and capable of acting in response to a remote-control signal in order to halt the filling of the tank, when the measured temperature drops below the ambient temperature. <IMAGE> <IMAGE></p> |
