Definitions

  • the present invention relates to a disposable gas lighter of the type comprising a pressure reducer constituted by a porous body maintained applied against a shoulder formed in the channel provided in the valve body for the passage of fuel and whose porosity characteristics, which correspond at the desired flow rate as a function of the desired flame height, are determined during manufacture, the upstream face of this pressure reducer communicating directly with the interior of the liquid fuel tank.
  • the present invention aims to reduce this cost price by considerably simplifying the construction of their valve.
  • the shoulder against which the pressure reducer is kept applied is formed directly in the body of the lighter of which it is an integral part, and with which it is produced. simultaneously in a moldable or injectable material and poor conductor of heat.
  • the support shoulder of the pressure reducer forming an integral part of the body of the lighter therefore eliminates the need to provide an attached valve body and its mounting before its installation, which obviously reduces the cost price of the lighter.
  • the pressure reducer of this lighter can be made by a disc of sintered material fixed by gluing, wedging or the like against its bearing shoulder. It can also be constituted by a porous or mesoporous membrane fixed to the shoulder provided for its support in any suitable manner, for example by gluing or welding carried out annularly around the fuel passage channel which surrounds the shoulder.
  • the pressure reducer is constituted by a porous or mesoporous membrane
  • its retention applied, by one of its faces, against the shoulder provided for its support is obtained by application, against its other face and under a predetermined pressure necessary for its peripheral sealing, an annular disc fixed to the body of the lighter by any suitable means such as by wedging, gluing or welding.
  • the pressure reducer In all cases where the pressure reducer consists of a porous or mesoporous membrane, it may be associated with a fibrous sheet applied against its downstream face in order to facilitate the circulation of the fuel radially in the direction of the channel leading to the burner.
  • this lighter in which there is no provision of calories from the valve burner to the downstream face of the pressure reducer, requires that the fuel passes through this reducer in the gas phase and that, consequently, part of the fuel is in the gaseous phase between the pressure reducer and the upper level of the liquid fuel contained in the tank, which prohibits its use in a strongly inclined position, or even completely overturned.
  • the fuel risks, in the liquid phase, penetrating into the pores of the reducer and thereby causing an unpleasant flickering of the flame.
  • the downstream face of the porous or mesoporous membrane is covered by a sheet of porous material and good conductor of heat such as a sheet of porous metal.
  • a sheet of porous material and good conductor of heat such as a sheet of porous metal.
  • valve burner in this lighter, there is no provision of calories between the valve burner and the downstream face of the pressure reducer allows the valve burner to be made of a moldable or injectable material which is poor in heat conductivity. .
  • the upper wall of the body (2) of this lighter which also constitutes the body of its tank (3) inside which is visible the upper level (4) of its liquid fuel, has two coaxial cylindrical projections (5) and (6) projecting, respectively on the outer face and on the inner face of the wall (2).
  • These two coaxial cylindrical projections (5) and (6) delimit a common cylindrical bore (7) closed by an annular shoulder (8) near the free end of the inner cylindrical projection (6).
  • the upper face of the annular shoulder (8) is shaped as a seat (9) on which normally rests the seal (11) of a valve burner (12) arranged in a manner known per se to be kept normally in closed position by spring means, not shown in the drawing, and to be brought into the open position during each operation of the ignition mechanism of this lighter.
  • the underside (8a) of the shoulder (8) is intended to constitute the bearing face or bearing shoulder of the pressure reducer (13) of this lighter, a pressure reducer which, in this example, is constituted by a mesoporous membrane (13a) on the upper or downstream face of which a fibrous sheet (13b) is applied.
  • the pressure reducer (13) is maintained by a disc (14) having a central fuel supply channel (15) which is fixed by gluing, welding, wedging or in any other way. re at the free end of the inner cylindrical projection (6), so as to exert on the pressure reducer (13) the annular zone delimited by an annular boss (14a) provided on the bearing face of the disc (14 ), sufficient pressure to ensure the peripheral tightness of the pressure reducer (13) and to oppose any circulation of the liquid fuel radially in the direction of the periphery of this pressure reducer.
  • the annular shoulder (14a) of the disc (14) provides in its center a cylindrical chamber (16) whose diameter determines the useful section of the pressure reducer (13).
  • the presence of the porous sheet (13b) of the reducer (13), downstream of the mesoporous membrane (13a), allows the circulation of the fuel radially in the direction of the channel (17) formed in the center of the annular shoulder ( 8), to allow the circulation of gas in the direction of the valve burner (12,11).
  • the shoulder (8) on the upper face of which is arranged the boss (9) constituting the seat of the valve (11), and the lower face of which constitutes the bearing shoulder of the pressure reducer (13 ), is an integral part of its body (2), which eliminates any need to provide an independent valve body previously mounted in isolation and placed in a well intended to receive it, as exists in lighters currently known .
  • this fixing is carried out by welding and more precisely by ultrasonic welding, the disc (14) being of a plastic material capable of being welded in this way to that constituting the body (2 ) and the projection (6) of the lighter.
  • the pressure reducer (13) is associated with a layer of porous material of good thermal conductivity (13c) which is applied to it against its downstream face, that is to say say sandwiched between the mesoporous membrane (13a) and the fibrous sheet (13b).
  • This layer (13c) can for example be produced by a porous metallic sheet. It results from the presence of this layer (13c) a temporary supply of calories sufficient to ensure instant evaporation of the fuel possibly present in the liquid phase in the pores of the mesoporous membrane (13a).
  • the pressure reducer (13) consists only of the single mesoporous membrane (13a) which allows it to be held against its support shoulder (8a) by bonding or welding which, in this case must be made annularly as illustrated in (18) in this figure 2.
  • the diameter of the bead (18) of bonding or welding obviously determines the useful section of the membrane (13a).
  • the pressure reducer (13) can also be formed not by a porous or mesoporous membrane but by a disc made of porous material of greater thickness, the fixing of which. can be provided in n i m - door any suitable manner and in particular by clamping or bonding.
  • valve burner (12) in this lighter, there is no provision of calories between the valve burner (12) and the downstream face of the pressure reducer (13), makes it possible to produce the valve burner ( 12) in a moldable or injectable material that is poor in heat conductivity.
