Abstract

An apparatus for the dosed supply of liquefied gases characterized in that it comprises a tubular support hermetically sealed by its two ends and provided therein with means for its hermetic coupling to the gas supply tank and to the tank to be refilled, respectively; inside this support there is a tubular segment of flexible material that fits against the stops of the same, being hermetically coupled to the bodies that seal its ends, and a second tubular segment arranged in axial direction, whose longitudinal opening at the top it is communicated with the inside of the supply tank with the interposition of a steering valve, and at its lower end it opens into a conduit that on one side opens onto the chamber determined by the said flexible conduit and on the opposite side communicates through the conduit. a corresponding nozzle and with interposition of a control valve with the interior of the tank to be filled; finally, an essentially verifiable jaw system is provided from the outside, acting on said flexible duct, in the sense of reducing the volume of the chamber originated by it, communicating a pressure to the liquefied gas contained therein, which it forces this gas to penetrate inside the tank, and determines an aspiration, when recovering its resting position, which produces a suction on the air contained inside the tank to be filled.
