  • FIG. 8 is a side view illustrating the jetting of fuel through the window of the outer, stationary valve member, particularly the clearance between the pattern of jetting fuel and the window through which simultaneous venting occurs;
  • FIG. 9 is a side elevation in section illustrating simultaneous charging and venting when the lighter reservoir is approximately half filled.
  • FIG. 10 is a side elevation in section illustrating overflow of fuel after completion of filling.
  • the filling valve of the present invention consists generally of an outer stationary member 10 and an inner movable member 12.
  • the top cylindrical section 14 of the outer stationary member 10 is provided with a threaded portion 16 while the casing 18 of the cigarette lighter is provided with a threaded portion 20, permitting the entire filling'valve assembly to be screwed within the lighter casing 18, gasket 22 preventing leakage of fuel.
  • the inner cylindrical wall 21 of the top segment I4 defines an opening or port within which the stem or spout 23 of the fuel-containing refill capsule is inserted.
  • the top segment 14 of the stationary member 10 is preferably metal.
  • the lower segment 24 of the outer stationary member 10 is cylindrical in configuration terminating downwardly in a bottom 26 which functions as a support, as explained hereinafter.
  • a single window 28 is provided within one side of the lower segment 24 while the other side of the segment 24 includes a flattened portion or abutting surface 30.
  • the lower segment 24 is preferably constructed of metal capable of being cold worked.
  • top and bottom segments are connected by cold welding; is. the top portion 32, cylindrical as manufactured and having an inner diameter smaller than the outer diameter of the lower portion 34, is forced over the lower portion 34.
  • the cold-welded connection the extremities of which are designated by reference numerals A-B, is airtight. Finally, the uppermost segment 33 of top portion 32 is compressed within the groove 36 of the lower portion 34.
  • the inner movable member I2 is a thermoplastic material, for example, DURACON acetal copolymer manufactured by Polyplastics Co., Ltd., Osaka, Japan. Since the inner, movable member 12 is a thermoplastic, for example, a copolymer of trioxane and others produced by polymerization, this most important element of the filling valve possesses many desirable engineering properties such as toughness, retention of shape under stress, springiness and stability under longtime service. Since acetal copolymers such as DURACON can be formed by injection molding, extrusion, blow molding and other established techniques, the cost of manufacturing the inner movable member I2 is reduced.
  • the heart of any gas lighter filling valve is the inner, movable member.
  • the inner movable valve member 12 should be capable of being produced at low cost by mass production techniques.
  • the inner movable valve member I2 must be designed so as to permit easy installation within the outer stationary member 10.
  • the inner movable member 12 must resist failure under stress and retain its shape during long periods of use. Permitting the introduction of fuel into the lighter reservoir and proper sealing of the reservoir from the outside when the valve is closed.
  • the inner movable member 12 must resist abrasion, particularly from the stem 23 of the refill capsule during the filling operation. It is important that the shape of the furrow 39 be retained throughout the life of the lighter.
  • the inner movable member 12 is unitary in construction, including from top to bottom a flattened tip 37, a conical section 38 provided with a furrow 39, a cylindrical section 40, a conical section 42, a cylindrical section 44, an inwardly spaced cylindrical section 46 (FIG. 2) around which gasket 48 is fitted, a conical section 50, a cylindrical section 52 and a large generally cylindrical base 54 provided with a hollow portion defined between sidewall 56 and central portion 58 within which a spring 60 is located.
  • the side wall 56 of the cylindrical section 54 is provided with a flattened portion or abutting surface 62 complimentary in configuration with respect to the flattened portion 30 of the lower segment 24 of the outer stationary member 10.
  • the inner movable member 12 is normally biased upwardly in its closed position (FIG. 2) by the force of spring 60.
  • Gasket 48 prevents the leakage of fuel between the top surface of the conical section 50 of the inner movable member 12 and the inclined surface or seat 35 of the upper segment 14 of the outer stationary member 10.
  • the stem 23 of the fuelcontaining refill capsule is pushed downwardly into the opening or port defined by the inner cylindrical wall 21 of the top segment 14 of the outer stationary member 10.
  • the stem 23 moves the inner member 12 downwardly against the force of spring 60 until the bottom 57 of the sidewall 56 contacts the bottom 26 of the lower segment 24 of the outer stationary member 10.
  • Suitable means are provided in the refill capsule permitting fuel to be released through stem 23.
  • a valve assembly is provided within the refill capsule for releasing the fuel as the lighter filling valve is opened.
  • the filling operation begins and liquified gas passes downwardly within the stem 23 and jets outwardly through the furrow 39 into the lighter reservoir along stream 64.
  • the direction of jet stream 64 is defined by the axis of furrow 39 and, accordingly, the taper of conical section 38.
  • a clearance or space is defined between the window 28 and the area occupied by the jetstream 64 within the window 28.
  • the liquified gas jetstream 64 impinges upon the walls of the lighter reservoir 66 and the level 68 of liquified gas begins to rise. Simultaneously, some fuel in gaseous state is exhausted or vented along path 70.
  • the level 68 of charged liquid fuel approximates the window 28 and the jetstream 64 collides against the charged liquid fuel level 68 near the window 28 and rebounds spraying back liquified gas along path 72, while gas bubbles 71 also begin to spray back.
  • This exhausting of significant quantities of liquified gas along path 72 is easily detected by the user signifying complete filling, at which time the refill capsule is removed and the inner movable member 12 permitted to rise to its closed position (FIG. 2).
  • a valve for filling the reservoir of a cigarette lighter with a low-pressure gaseous fuel from a refill capsule having a spout comprising:
