Definitions

  • the present invention relates to a safety gas lighter.
  • Gas lighters comprising a liquid gas tank and a valve disposed at the outlet of this tank, said valve comprising a movable assembly between a position where it closes the outlet of the tank and a position where it allows the passage of liquid gas from this orifice to a regulator where the gas is vaporized to be burned, said valve comprising a seal between its movable assembly and a fixed seat.
  • the movable assembly of the valve is biased by a spring towards the position where it closes the outlet orifice of the tank.
  • a pusher-type member keeps the valve open during the use of the lighter. As soon as this pusher is released, the valve closes by itself and the lighter goes out. This has various drawbacks, especially when the lighter is used to light a pipe.
  • the mobile assembly is biased by a spring towards the position where it allows the passage of liquid gas. In this case it is generally the closing of a lighter cover which causes the valve to close.
  • the most serious disadvantage of a lighter of this type lies in the fact that if it is dropped by its user while it is in operation it risks remaining so during its fall and possibly causing an accident. .
  • the present invention aims to overcome these drawbacks by providing a lighter which it is not necessary to keep a button pressed to allow its operation but which nevertheless goes out quickly after being actuated.
  • the subject of the present invention is a gas lighter comprising a liquid gas reservoir and a valve disposed at the outlet orifice of this reservoir, said valve comprising a movable assembly between a position where it closes the orifice of outlet and a position where it allows the passage of liquid gas from this orifice to a regulator where the gas is vaporized to be burned, said valve comprising a seal between its movable assembly and a fixed seat, characterized in that an intermediate chamber is provided in the valve between the seal and the regulator.
  • valve in such a lighter the valve can be opened and instantly closed. Indeed, during the opening time the intermediate chamber is filled with liquid gas which even after closing the valve, at the seal, can relax and burn. As long as liquid gas remains in the intermediate chamber, the pressure in it is constant so that the flame supplied by the lighter has a substantially constant height.
  • the intermediate chamber is a substantially cylindrical chamber formed inside the mobile assembly.
  • the mobile assembly may comprise at least one radial bore capable of making the intermediate chamber communicate with an annular passage for the liquid gas situated between the seal and the intermediate chamber.
  • the intermediate chamber may be an annular chamber formed between the movable assembly and a fixed outer part of the valve.
  • the mobile assembly may include at least one radial bore between the intermediate chamber and the regulator.
  • a seal may advantageously be provided between the movable assembly and the fixed outer part of the valve beyond the radial bore.
  • a wick is arranged in the intermediate chamber.
  • the lighter shown in Figures 1 and 2 has a body 1 which carries a valve 2 and forms a reservoir 3 for liquid gas.
  • the valve 2 is arranged in the orifice 4 of the reservoir 3 between a supply pipe 5 for the liquid gas and a burner 6 mounted on a closing cover 7 of the briqnet.
  • the valve 2 comprises in known manner a substantially cylinder body 8 engaged in the orifice 4 and of which the conduit 5 is integral. Inside the body 8 and bearing on the upper part of the conduit 5 is a member 9 which forms at its lower part a seat 10 for a seal which will be described below.
  • the member 9 is held in place by a member II which is threaded externally at its upper part to cooperate with an internal thread 12 of the body 8.
  • a member II which is threaded externally at its upper part to cooperate with an internal thread 12 of the body 8.
  • This movable assembly firstly comprises a member 13 which comprises at its lower part a seal 14 retained by a ring 15.
  • the member 13 is capable of sliding with play inside a bore formed in the organ 9.
  • the member 13 In its middle part the member 13 has a central bore 16 which communicates at its lower part by a radial bore 17 with the outside of the member 13, that is to say which opens into the bore of the organ 9.
  • the axial bore 16 communicates with the regulator 18 which will be described below.
  • a wick is arranged in the bore 16 between the bore 17 and the regulator 18. This wick improves the stability of the combustion of the gas mixture.
  • the movable assembly also comprises a member 19 above the member 13, the member 19 also being pierced axially.
  • the member 19 forms at its upper part an exhaust duct 20 ending near the burner 6 and comprises at its lower part a bore in which the threaded rod of a screw 21 is arranged.
  • the member 13 also comprises at its upper part an internal thread 22 capable of cooperating with an external thread of an adjustment member 23.
  • the lower surface of the member 23 is supported on a shoulder of the member 19 which is itself engaged in the member 13.
  • Between the member 13 and the member 19 is the head of the screw 21 as well as a material of any type known for forming the regulator 18.
  • a spring 24 is disposed between the bottom of the member 11 and an external shoulder of the member 13.
  • the member 13, the screw 21, the regulator 18, the member 19 and the member 23 form an integral assembly sliding axially inside the body 8 of the valve 2.
  • This movable assembly is pushed upwards by the spring 24 so that, in the absence of any external action, the seal 14 is in abutment on the valve seat 10.
  • a seal 25 is disposed between the member 9 and the member 13 above the radial bore 17, that is to say downstream of this bore in the direction of flow of the gas and another seal 26 is provided between member 13 and member 19.
  • a pusher 27 is provided at the upper part of the lighter in a place accessible by the user's finger and is capable of sliding through the cover 7 in the axial direction.
  • the pusher 27 is arranged to drive the free end of a leaf spring 28, the other end of which is secured with a screw 29 to the body 1 of the lighter.
  • the leaf spring 28 In its central part, the leaf spring 28 has an orifice which is traversed by the upper part 20 of the member 19 so that when the pusher 27 is pressed the spring 28 biases the mobile assembly of the valve 2 downwards against spring action 24.
  • the gas then rises in the threads of the screw 21 where it is homogenized and then it passes through the exhaust duct 20 from which it exits through the burner 6.
  • a spark triggered by the user then makes it possible to ignite the gas.
  • the intermediate chamber 16 Since the intermediate chamber 16 is full of liquefied gas, it continues to escape by vaporizing in the regulator 18. However, as long as liquid gas remains in the chamber 16, the pressure retains the same value so that the flame at the outlet of the burner 6 retains the same height.
  • the pusher 27 is pressed again, the intermediate chamber is again filled with liquid gas so that the flame returns to its initial height.
  • FIGS 3 and 4 show a variant of the lighter according to the invention and in these figures only the valve 30 has been shown.
  • the valve 30 comprises, as previously, a fixed external part 3 1 inside which is capable of sliding axially a movable assembly formed by a member 32, a member 33 disposed inside the member 32 and an adjusting member 34 externally threaded to cooperate with an internal thread of the member 32 and pressing by its lower surface on a shoulder of the member 33. Between the lower part of the member 33 and a bearing surface of the member 32 is disposed the regulator 35, the degree of compression of which can be adjusted by screwing the adjusting member 34.
  • the member 32 has at its lower part a seal 36 held by a ring 37 crimped on the member 32.
  • the seal 36 is capable of cooperating with a seat 38 formed at the lower part of the member 31.
  • the seat 38 consists of the outer surface of an annular rim, the inner surface of which serves as a support for a helical spring 39, the other end of which bears on a shoulder of the member 32.
  • Another seal 40 is disposed between the member 32 and the member 31 as well as a third seal 41 is disposed between organs 32 and 33.
  • An annular space 42 formed between the member 32 and the member 31 corresponds to its lower part which contains the spring 39 with the zone 43 for the arrival of the liquid gas via the valve seat 38 and to its upper part with the regulator 35 by means of a radial bore 44 located below the seal 40.
  • the body 33 has at its upper part an exhaust duct 45 for the vaporized gas.
  • the driving members of the mobile assembly formed by the members 32, 33 and 34 have not been shown but they allow this assembly to slide down against the action of the spring 39.
  • the seal 36 When the seal 36 is moved away from the seat 38 the liquid gas can penetrate into the annular intermediate chamber 42 (FIG. 4) from which it can pass into the regulator 35 by the radial bore 44. From the regulator 35 the gas passes through the exhaust duct 45 after which it is burned using a burner not shown.
  • the intermediate chamber 42 is again filled with liquid gas so that the flame returns to its initial level.
  • the invention therefore makes it possible to produce a lighter in which it is not necessary to keep a push button depressed to ensure the escape of the gas.
  • this lighter is safe to use because it goes out quickly in the event of a fall.
  • the user is warned that the lighter is about to go out by the reduction in the height of the flame so that it is sufficient for him to depress the valve lifter again to refill the intermediate chamber of liquid gas which can burn without the need to supply a new spark.
