Definitions

  • the present invention relates to a device for adjusting the gas flow rate for a liquefied gas lighter and, in particular, a device for adjusting the maximum flow rate and therefore the maximum height of the flame delivered by the lighter to a given value.
  • lighters are known in which the flame delivered is limited below a given value, using means causing an additional pressure drop, these means being arranged in series with the normal device for flow adjustment.
  • Such devices as soon as they use a compressible pad, have, of course, the same creep defects as conventional regulators.
  • the present invention aims to propose a device for adjusting the gas flow rate of the aforementioned type which allows, on the one hand, to adjust the flame supplied below a given value and which, moreover, makes it possible to minimize the phenomenon creep and its consequences on the stability of the flame.
  • this device for adjusting and limiting the gas flow rate for a liquefied gas lighter of the type comprising at least one compressible element traversed by the gas, and means for compressing this element more or less according to the flow rate.
  • this device being characterized in that said compressible element consists of a permeable disc in contact at its periphery with a coaxial permeable ring, in that the path of the gas in the disc and the ring is substantially radial, and in that each of the external faces of said disc and of said crown is in contact, by substantially all of its surface, with any element of the device or of the lighter, in order to avoid or reduce the creep phenomena of said compressible element.
  • the permeable disc is made of a compressible material whose adjustment of the compression level makes it possible to adjust the flame to the desired given height.
  • the permeable crown may be made of a sintered material, the porosity of which, determined during manufacture, makes it possible to define the maximum flame delivered by the lighter. It also ensures that the permeable disc is maintained and, therefore, prevents any creep of the latter at its periphery. On the other hand, in the case where the gas is supplied from the periphery, the permeable ring makes it possible to ensure a uniform supply of the central disc, since it is carried out over the whole of its entire external surface.
  • said disc can be made of a rigid material, for example sintered, and the crown be of a compressible material.
  • feeding can take place from the center of the disc and exit from the periphery surface of the crown.
  • the permeable disc in order to avoid creep at the level of the central channel (gas inlet or outlet), the permeable disc is in contact by substantially all of its external surface with any element of the device. It is thus possible to have in the central channel a stud crossing the compressible disc, or a cylinder made of a permeable material, such as, for example, a sintered material, the space provided between this stud and the channel as well as the dimensions of the pores of the sintered material being both large enough not to cause a significant pressure drop, and small enough so that the compressible material cannot flow therein.
  • a permeable material such as, for example, a sintered material
  • the disc and the crown are each made of a compressible permeabal material, so as to allow both the preset of the maximum flame and the adjustment of the flame of use.
  • the disc and the crown which is associated with it are made up of a single piece compressed into two different zones: on the one hand, a central circular zone and, on the other hand, an annular zone surrounding it.
  • This arrangement simpler and easier to implement, has the same advantages as the previous embodiment.
  • the flame height adjustment device is arranged inside an internally threaded cavity 5, formed in a tube 1 secured to the bottom 3 of the body of the lighter.
  • a resilient permeable disc is disposed on the bottom of the cavity 5.
  • a permeable crown 7, made of sintered metal, is disposed at the periphery of this disc, in contact with it.
  • a washer 8 seals the gas between the crown 7 and the tube 1.
  • the crown 7 is held by a screw 9 screwed into the cavity 5, with the interposition of a washer 10 between the screw 9 and the crown 7.
  • the disc 12 is compressed in its central part by a compression element 13 screwed by a thread 15 in the tube 1.
  • Two O-rings 17 and 19 ensure respectively the seal between the compression element 13 and the screw 9, of a on the other hand, and between the body 3 and the compression element 13.
  • the tube 1 is pierced with orifices 20 and 22 communicating respectively the interior of the cavity 5 with the gas tank of the lighter and with the burner.
  • the compression element 13 is provided with a stud 11 passing through the disc 12.
  • the space existing between this stud and the channel 22 is such that it is large enough not to cause significant pressure drop, and sufficiently small so that the disc 12 cannot flow there.
  • the operation of the device is as follows: the gas coming through the orifices. 20 from the reservoir borrows the capillary channel defined by the threads of the screw 9 and the cavity 5 to reach the periphery of the disc 7. It passes through this disc undergoing a first pressure drop depending on the porosity of the sintered crown, determined during manufacture. It then crosses the disc 12 radially, undergoing a second pressure drop depending on the state of compression of this disc. When the valve 23 is open, the gas finally borrows the channel 22 of the burner not shown in the drawing. Note that the disc 12 is held on all its faces by the various elements of the device and, therefore, cannot, over time, undergo significant creep phenomena.
  • Fig. 2 is a partial view of an alternative embodiment of the device of FIG. 1.
  • the organs already described in relation to FIG. 1 or having equivalent functions are designated by the same reference numbers, assigned the index '.
  • the crown 12 is replaced by a disc 12 '.
  • the crown 7 ′ and the disc 12 ′ consist of two permeable compressible materials and are compressed respectively by the screws 9 ′ and 13 ′ which make it possible to adjust the height of the maximum flame and the height of the use flame delivered by the lighter.
  • a porous cylinder 6, made of a sintered material, is fixed in the gas outlet channel in contact with the disc 14. Its porosity is sufficient not to create a significant pressure drop as the gas passes. During compression, the disc 12 'bears on said cylinder 6 and, therefore, cannot flow in the gas outlet channel 22'.
  • the central disc and its crown are made up of a single piece, a disc 34, and the flame height adjustment is carried out from the upper part of the lighter.
  • This is pierced with a cavity 31, in which is housed a sub-assembly consisting of a support 32, in an internal recess 35 of which is disposed the elastic permeable disc 34.
  • the latter is compressed axially by a screw 36 screwed into an internal thread of the recess 35.
  • a centering pin 36a of the screw 35 is engaged in an axial orifice of the disc 34.
  • the upper part of the support 32 is pierced with an orifice 37 in which a compression element 38 is engaged.
  • This is applied against the central part of the disc 34 by a screw 40, which is screwed into the cavity 31 of the body of the lighter and which can be operated from the outside.
  • This screw 40 has a central channel 42 receiving a burner 44, one end of which is provided with a valve 46. The latter bears on the upper face of the compression element 38 and closes a channel 48, making the disc communicate. 34 with the burner.
  • the operation of the device is as follows: the gas arrives from the reservoir through a channel 50 opening at the base of the cavity 31, passes through the capillary part between the threads of the screw 36 and of the support element 32, to arrive at the periphery of the disc 34. It then crosses it radially to gain channel 48 of the compression element. When the valve 46 is open, the gas then reaches the channel 52 of the lighter burner.
  • the device for adjusting the gas flow rate according to the invention is housed in a cavity 60 of a tube 62.
  • the bottom of this cavity communicates with a burner, not shown in the drawing, by a channel 66 which can be closed off by a valve 68.
  • a metal disc 70 provided on its upper part with fine radial grooves 61 and comprising a central stud 72 oriented towards the inside of the cavity 60 is disposed on the bottom 64 of said cavity.
  • the permeable disc and crown are combined into a single disc 74, compressed on its annular part by a screw 76 screwed into the tube 62, and in its central part by a piston 78 passing through a bore 80 of screw 76.
  • the piston 78 is hollowed out with a gas inlet channel 82 and a stud 72 of the metal disc 70 crosses the disc 74 to penetrate the channel 82, thereby minimizing creep at the level of the central channel.
  • the operation of the device is as follows: the gas coming from the lighter tank, not shown in the drawing, is admitted through the capillary channel formed by the space formed between the bore 80 and the piston 78 and reaches the center of the permeable disc 74 by borrowing the conduit 82. It then crosses the two compression zones of the disc 74, where it undergoes a pressure drop depending on the position of the piston 78 and of the screw 76, then it gains the channel 66, by borrowing the grooves 64.
  • the invention therefore provides a simple and safe device for adjusting the gas flow rate of a liquefied gas lighter, which, at the same time, remedies the creep problems posed by the devices of the prior art and makes it possible to adjust to a value given the maximum flame and the use flame delivered by a lighter.
