Charging apparatus for liquefied gas lighters

Claim 1

A CHARGING APPARATUS FOR LIQUEFIED GAS LIGHTERS, COMPRISING IN COMBINATION: A FIRST FUEL GAS CONTAINER, AN INJECTION VALVE AND A SUPPLEMENTARY FILLING VALVE, SAID INJECTION VALVE COMPRISING AN OUTER CYLINDRICAL BODY MEMBER ADAPTED TO BE SECURED TO SAID FIRST FUEL GAS CONTAINER AND HAVING TWO OPPOSITELY DISPOSED OPENINGS IN THE SIDE WALL THEREOF, AS WELL AS AN INNERMOST INNER FACE, SAID OUTER CYLINDRICAL BODY MEMBER INCLUDING AN INWARDLY DIRECTED ANNULAR VALVE SEAT DISPOSED OUTWARDLY OF SAID OPENINGS, AN INNER VALVE BODY AXIALLY MOVABLE IN SAID OUTER CYLINDRICAL BODY MEMBER AND INCLUDING AN INWARDLY FACING SHOULDER PORTION NEAR ITS OUTER END, A FIRST PACKING MEANS RECEIVED IN AND DISPOSED ON THE OUTER FACE OF SAID VALVE BODY AND ENGAGING SAID ANNULAR VALVE SEAT IN THE CLOSED POSITION OF SAID INJECTION VALVE, A FIRST COIL SPRING DISPOSED BETWEEN SAID INNERMOST INNER FACE OF SAID OUTER CYLINDRICAL BODY MEMBER AND SAID SHOULDER PORTION OF SAID VALVE BODY AND URGING THE LATTER INTO ITS OUTERMOST VALVE SEAT ENGAGING POSITION, SAID SUPPLEMENTARY FILLING VALVE COMPRISING A CONTAINER BODY AND A VALVE STEM PROJECTING FROM SAID CONTAINER BODY AND HAVING A NECK PORTION AND AN AXIAL PASSAGE CLOSED AT ITS INNER END AND OPEN AT ITS OUTER END, A SKIRT MEMBER HAVING AN INNER BASE FACE AND RECEIVING THE INNER END OF SAID VALVE STEM, SAID SKIRT MEMBER BEING RETAINED IN THE OUTER END OF SAID CONTAINER BODY, A SECOND PACKING MEANS DISPOSED AT THE OUTER END OF SAID SKIRT MEMBER AND RECEIVED IN SAID NECK PORTION OF SAID VALVE STEM, A SECOND COIL SPRING DISPOSED BETWEEN SAID INNER BASE FACE OF SAID SKIRT MEMBER AND SHOULDER OF SAID VALVE STEM TO URGE THE LATTER INTO ITS OUTERMOST POSITION, THE OUTER PORTION OF SAID VALVE STEM EXTENDING INTO SAID OUTER CYLINDRICAL BODY MEMBER OF SAID INJECTION VALVE AND THE OUTER END OF SAID VALVE STEM ENGAGING THE OUTER FACE OF SAID FIRST PACKING MEANS IN ITS OPERATIVE POSITION WITH SAID INJECTION VALVE, SAID VALVE STEM HAVING A FIRST RADIAL PASSAGE DISPOSED AT THE INNER END OF SAID AXIAL PASSAGE THEREOF AND A SECOND RADIAL PASSAGE DISPOSED AT THE OUTER END OF SAID AXIAL PASSAGE THEREOF, BOTH SAID RADIAL PASSAGES COMMUNICATING WITH SAID AXIAL PASSAGE, SAID SECOND PACKING MEANS SEALING SAID FIRST RADIAL PASSAGE IN THE INOPERATIVE POSITION OF SAID VALVE STEM, SAID FIRST RADIAL PASSAGE FEEDING FUEL, UPON PRESSING SAID VALVE STEM AGAINST SAID INNER VALVE BODY TO MOVE THE LATTER INWARDLY AGAINST THE PRESSURE OF SAID FIRST COIL SPRING, THROUGH SAID AXIAL PASSAGE OF SAID VALVE STEM AND SAID SECOND RADIAL PASSAGE INTO SAID INJECTION VALVE IN THE OPERATIVE POSITION OF THE LATTER, WHEREIN SAID VALVE STEM IS PUSHED INTO SAID CONTAINER BODY AGAINST THE PRESSURE OF SAID SECOND COIL SPRING, AND THROUGH ONE OF SAID OPENINGS OF SAID OUTER CYLINDRICAL BODY OF SAID FIRST INJECTION VALVE INTO SAID FUEL GAS CONTAINER, THE OUTER DIAMETER OF SAID VALVE STEM BEING SMALLER THAN THE INNER DIAMETER OF SAID OUTER CYLINDRICAL BODY MEMBER TO DEFINE AN ANNULAR CHANNEL THEREBETWEEN AND SAID ANNULAR CHANNEL COMMUNICATING WITH ANOTHER OF SAID OPENINGS OF SAID OUTER CYLINDRICAL BODY IN THE OPERATIVE POSITION OF SAID VALVE STEM, THEREBY PERMITTING BLEEDING OF SAID INJECTION VALVE DURING THE FILLING OPERATION.
