The LNG fuelling nozzles are plugged to the vehicles propelled by natural gas specifically in a coupling means of the fuel tanks. During the unplugging of said nozzles once the tank has been filled cause always inevitably a gas leak and in the event of a leak during the filling there is a leak near the user which, in addition to be hazardous, pollute the environment and economically harms the user. For this reason the invention proposes a solution consisting of channeling the gas from these leaks to a supplementary tank and, from it to the supply tank, recovering all the leaks, for which a pipe is used as main elements of the device, which is coupled to the bayonet by means of a seal connector made of Teflon or similar material and, a check valve at the inlet of the supplementary tank, said seal can be incorporated either in the bayonet or in the receptacle.
An anti-leak device applicable to gas fuelling nozzles, forming part of a LNG dispensing apparatus, said nozzles incorporating a quarter-turn bayonet which is formed by an upper part, a central part and a base, which in working position are introduced in a female socket base assembly or receptacle forming part of the fuel tank of the vehicle or source tank, wherein said anti-leak device includes means of recovery of the gas existing between the nozzle and the receptacle in the disconnection operation of the nozzle from the receptacle of the fuel tank, wherein said means of recovery of said residual gas comprises:
A gas fuelling nozzle to be coupled to an LNG receptacle of a fuel tank of a vehicle, said gas fuelling nozzle comprising an “Ice Breaker” type nozzle having hoses, the gas fuelling nozzle comprises an external body, an inner body that is moves axially of the outer body by means of levers, being connected to a central body, and in the lower part of the “Ice Breaker” type nozzle providing a quarter-turn bayonet which is engageable to a fuel tank receptacle of a gas-propelled vehicle, said quarter-turn bayonet which is formed by an upper part, a central part and, a base which in the working position is inserted in the receptacle, characterized in that the nozzle further comprises an anti-leak device including means for recovering the gas existing between the nozzle and the receptacle in the disconnection operation of the nozzle from the receptacle of the fuel tank, wherein said means for recovering said residual gas comprises:
