Definitions

  • ABSTRACT [30] Foreign Application Priority Data For a gas lighter to be replenished with liquefied gas May 30.
  • I972 German 12226224 from a filler bottle with a nozzle, a filler valve has within a housing a valve stem spring loaded to close a 52 us. c1 141/295; 251/323 a with the housing- The clearance between the m [51 ⁇ Int. Cl. ,4 Flfik 15/02; F23 2/52 and the housing provides a filler channel and the end [58] Field of Sear h 137/323; 141/2 [8, 193 face of the valve stem facing the nozzle has at least 141/291-296. 31 l. 329. 34635l. 353. 367.
  • valve housing having a sloping internal sholder around the outer end of the valve [56] References Cited stern to seal off the nozzle.
  • Thissinvention relates tofillervalvesfor-lighters to-"be replenished itwith liquefied gas from a; filler! bottle wherein a. movable valve element vincluding a stern within a valve housing is spring loaded-f seal against the valve housing.
  • the clearance around the valve stem provides a filler channel
  • the end surface of the valve stem facing the nozzle has one or more depressions or elevations providing a path opening to the inner wall of the valve housing and the valve housing is provided with a sloping internal shoulder somewhat beneath the upper edge to seal off the nozzle.
  • valve consists of only two parts movable against one another under spring pressure, i.e., the smallest possible number of parts
  • the sloping shoulder conveniently integral with the housing, provides a seal, the shoulder acting like a ball seal in cooperation with the nozzle of the filler bottle, conventionally of a plastics material.
  • seal consistsof an O-ring lying against a flange or shoulder of the valve stem to; encircle .the latter and to be fpr essed against the valvjeghousing.
  • FIG. 1 is a sectional view through a-filler valve in the rest position and in the position during filling
  • FIG. la illustrates a variant construction of the upper "part of a fillerv valve
  • FIG. 2 illustrates a variant constructio part.
  • the filler valve comprises a mov- -able valve element'l havinga 'springloaded stem 14 which slides loosely in a valve: housing2 and carries at its inner end a sealing ring 3 on a flange or shoulder 12.
  • the sealing ring 3 is pressed against an end face 26 of the housing to close the valve.
  • the pressure results from the spring loading provided by a helical spring 4 encircling the valve stem 14 within the housing 2, which spring is seated on a shoulder 11 of the valve stem and on an internal end face 22 of the housing.
  • the outer end face 13 of the valve stem 14, that is, the exposed and uppermost end face when the lighter is held in position for filling, has a depression extending across it to the face edges to provide paths opening to the inner wall of the housing.
  • the valve housing 2 is screwed into a lighter case 20 by means of a thread 24 and sealed gas-tight by a seal 21.
  • the depression 130 in the upper end of the valve stem is shown in FIG. 1 and to the right of FIG. 10 as a wide shallow trough extending diametrally across the face 13, so that the face presents, along the sides of the trough, two rising lands to be engaged by the nozzle of the filler bottle.
  • the face may be shaped in other ways for the free flow of liquefied gas to the inner wall of the housing.
  • the face 13 may for example have sides 13! sloping to a diametral elevation or peak providing a rising land to be engaged by the nozzle of the filler bottle.
  • the flat seal 3 of FIG. I is replaced by an O-ring 33.
  • a flange or shoulder I21 has an annular rim 122 which lies against the O-ring 33 tightly surrounding the valve stem 14. The O-ring is pressed by spring 4 against the end face 26 of the valve housing and a face 140 of the flange or shoulder 12] of the valve stem and thus forms a gas seal 27 between the valve element comprising stem 14 and valve housing 2. In this way, a gas-tight connection of the flange or shoulder 12] with the valve stem 14 is no longer necessary.
  • the flange or shoulder 121 may be a ring affixed by riveting.
  • a filler valve for a lighter to be replenished with liquefied gas from a filler bottle having a nozzle comprising a valve housing providing a throughway with an inner end presenting a valve seating face and an outer end stepped to receive and then to seal with the nozzle of an applied filler bottle, a depressible valve stem with clearance in the throughway, a sealing ring on said stem. and spring loading means for urging the stem to press the sealing ring against said valve seating face to close the valve, said stem having for engagement by the applied nozzle an end face which is substantially flush with the outer end of the throughway when the valve is closed and has at least one depression providing a flow path across said end face to the edge thereof, so that.
  • a filler valve according to claim 1, wherein said end face having at least one depression is a face with a trough extending across from edge to edge.
  • a filler valve according to claim 1, wherein said end face having at least one depression is a face with a peak extending across from edge to edge.
