Definitions

  • the present invention relates to gas appliances, in particular with liquefied petroleum gas, comprising a burner supplied by a injector.
  • gas appliances in particular with liquefied petroleum gas, comprising a burner supplied by a injector.
  • These devices can be stoves, lamps, torches and others.
  • FR 1 368 185 describes a valve box for bottles with liquefied gas allowing to feed indifferently, from gas cylinders at various pressures, such as propane and butane, the same device receiver.
  • the valve box regulates the flow rates by transposing the stroke of the pressures in the ratio of the diameters of a differential piston.
  • FR 1 508 276 describes a supply nozzle for a burner gas can be used equally on devices supplied with butane or propane.
  • the invention relates to a gas appliance which is very simple to manufacture and which can be connected either to a gas source having a first vapor pressure or another source of gas having a second voltage vapor different from the first.
  • the invention therefore relates to a gas appliance, in particular a liquefied petroleum gas according to claim 1.
  • the size of the outlet openings and in particular their diameter, easily and automatically adapts to the gas source.
  • the first gas is in particular butane and the second gas propane.
  • the axis of the burner is vertical which implies that the injector is subjected to the force of gravity and moves in depending on its weight and the forces applied to it by the gas of liquefied petroleum, namely, pressure and also variation in flow.
  • German patent application No. 3700233 (Buderus), we describes a device in which the injector 2 is subjected to the action of a gas relaxed from 20 to 50 millibar and the force applied by a spring 3. There are thus antagonism only between the forces of pressure and the forces of the spring, while, according to the invention, there is in addition to an antagonism of pressure forces and the force of gravity, a force due to the variation of flow, which causes the secondary injector 6 to rise suddenly.
  • the invention has the advantages of not requiring a precise calibrated spring practically impossible in fact to produce in large series in injector diameters of about 10 mm, and expensive. She does not also does not require precise machining so that the injector does not get stuck not in the upward movement, on the one hand because there is an interval between them and on the other hand, because the injector is not subject to the action of a spring which can be misaligned.
  • the envelope can be in particular cylindrical and the secondary injector have a polygonal cross section inscribed in the envelope section.
  • sealing means acting are provided between the casing and the secondary injector in the second position. These means sealants ensure as much as possible that propane does not pass directly through the main outlet port without first passing through the secondary outlet which limits the flow.
  • the stove shown in Figure 1 includes a body 1 with vertical axis defining a burner 2, which communicates through an orifice 3 main outlet with the inside of an envelope 4, which has a part conical upper into which opens the main orifice 3 and a part cylindrical which opens downwards through a fitting 5 inlet into a cylinder B of liquefied petroleum gas.
  • the part of the envelope 4 in which slides the injector Secondary 6 has a circular section, while the injector section 6 secondary is polygonal by being inscribed in the section of envelope 4 so that there are gaps 8 between the casing 4 and the injector 6 secondary, intervals 8 by which gas from cylinder B and inlet 5 connector can go directly to the main outlet port 3 without pass through the secondary outlet orifice 7 when the secondary injector 6 is, under the effect of gravity, in the lowest position near the bottle B.
  • the diameter of the secondary outlet orifice 7 is smaller than that of the main outlet 3.
  • the secondary injector 6 has a central chimney 9 connecting the secondary outlet orifice 7 and the connector 5 of the bottle.
  • An O-ring 10 is also provided which, in the second position shown in Figure 1, applies to the frustoconical part envelope 4 and thus prevents gas from coming directly from the bottle B via connection 5 and gap 8 at main outlet 3. In however, when the secondary injector 6 is in the lower or first position position, the O-ring 10 moves away from the wall of the casing 4 and allows butane gas from a cylinder B arriving directly at port 3 main output.
  • the main injector 6 takes the position shown in the figure and the propane can only reach outlet 3 by first passing through secondary outlet 7 of smaller diameter and therefore with a flow rate less.
