Definitions

  • This invention relates to an improved portable apparatus which utilizes pressurized gas fuel.
  • the fuel container consists of a pressure-tight container or cylinder provided with an outlet hole or discharge opening which contains a closure valve.
  • the burner appliance such as the torch head, stove, lamp or the like, has a tap arrangement provided with an elongated hollow stem.
  • the hollow stem is inserted in the discharge hole or opening in sealing contact with a sealing member positioned in this hole as, for example, a resilient O ring.
  • the elongated stem thendepresses the valve positioned in the discharge Opening, opening the same, and allowing gas communication from the interior of the cylinder through the hollow stem to the burner appliance.
  • An additional adjusting valve may be provided in the gas conduit leading from the stem to the burner appliance.
  • the discharge hole or opening from the container may be provided through a threaded plug which may be screw-connected with a corresponding threaded sleeve, at least partially surrounding the stem to make the connection.
  • the container may comprise a throw-away cylinder which is purchased full of the liquetied fuel and which is thrown away when empty.
  • One object of this invention is an improved discharge from a portable pressurized fuel container which completely overcomes the above-mentioned difiiculties and insures an even discharge from the cylinder under all operating conditions and positions of the cylinder.
  • Fig. 1 is a side elevation of an embodiment of a torch in accordance with the invention
  • Fig. 2 is a partial vertical section of the torch shown in Fig. 1;
  • Fig. 3 is a vertical section showing the details of the valve and pressure-reducing valve assembly in accordance with the invention.
  • the discharge passage from the cylinder leading to the burner appliance contains a valve which seats against the gas pressure in the container, and is resiliently urged towards its seating position, as, for example, by a spring with a predetermined force, that this valve will act as an accurate pressure-reducing valve, allowing the outlet passage of gas therethrough while minimizing the flow of liquid and will insure an even, uniform flow of gas to the burner of the appliance irrespective of pressure changes in the cylinder and/ or its operating position.
  • the throwaway pressure cylinder 1 as, for example, for liquid propane, has the torch head 2 attached.
  • the torch head 2 has a conventional burner for soldering, brazing, sweat-fitting, or the like.
  • the cylinder as may best be seen from Fig. 2, comprises a cylindrical pressure-tight hollow cylinder with an upper and lower cylindrical part, which may be formed, for example, by spinning or drawing.
  • the upper cylindrical part as shown, is fitted into the lower cylindrical part and joined thereto, as, for example, by brazing, welding or the like.
  • the upper cylindrical part has a hole indicated at 3 into which is inserted a substantially cylindrical plug 4 which is sealed in place in a pressure-tight manner by a pressfitting, brazing, soldering, Welding or the like.
  • the plug 4 has a central bore 5, which extends longitudinally therethrough, and which decreases in diameter in a step-Wise manner toward the interior of the cylinder.
  • a standard tire valve 8 is screwed into the threaded portion 6 of the bore and seals the bore with the gasket seal at 7.
  • the outer portion of the plug 4 is male-threaded at 9
  • the top connection and valve assembly 11 of the torch head 2 is formed at its base portion as a female-threaded sleeve 11, which is screwed in engagement with the thread 9 of the plug 4.
  • the assembly 11 has the elongated stem 12, which extends into the bore 5. As the assembly 11 is screwed into on the cylinder, the stem 12 makes contact with the elastic Q ring seal 13, sealing the annular space formed between the stem 12 and bore 5.
  • the stem 12 presses on the stem 14 of the tire valve 8,. opening the tire valve.
  • the stem 12 is hollow and has a. gas passage extending longitudinally therethrough in communication with the passage 15. Gas can thus pass from the cylinder through the valve 8, which is held in the open position by the stem 10 through the interior or the stem 10 to the passage 15.
  • the needle valve 17 controlled by the thumb screw 18, may close or vary the communication between the passage 15 and the passage 16, leading to the burner head.
  • the flame of the burner head may be controlled by the thumb screw 18.
  • the same may lead to the burner of any appliance as, for example, a burner of a stove or a lamp or the like.
  • the stem 12 has the hollow bore 19 extending longitudinally therethrough, in which there is positioned the valve 20.
  • the valve 29 has a resilient seal, such a a rubber seal 21, which seats on the shoulder 22 in the bore 19 to seal the bore.
  • the valve 20 has a guide pin 21 and a spring 22 urges the same toward the seated position.
  • the spring 22 is maintained in place, by means of a pressed plug 23 with an orifice 24, which allow passage of the gas therethrough.
  • the pressure of the gas from the cylinder acts against the valve 20 and lifts the same, allowing a constant and uniform flow of gas therethrough dependent on the pressure of the spring 22.
  • the valve 20 will prevent droplets of liquid from passing up through the bore 19 and thus prevent clogging and extinguishing of the flame during operation.
  • the tension of the spring 22 should be so set that the valve 20 will lift and allow the passage of gas therethrough at any pressure above the minimum pressure of satisfactory operation of the gas appliance.
  • the cylinder in operation may be utilized to the greatest maximum extent.
  • the flame will remain at this setting, regardless of the position of the container, etc., even if the container is completely inverted.
  • a portable gas fuel appliance having a container for pressurized fuel with a discharge opening, a valve member closing said discharge opening and a tap connection for said discharge opening including an elongated stem member with a longitudinal bore for insertion into said discharge opening to contact and forcibly open said valve member, the improvement which comprises a pressure reducer and regulator comprising valve means positioned in the longitudinal bore of said stem member freely movable to close in a direction against the pressure in said container, and means for resiliently urging said valve means closed with a lesser force than the force exerted by the pressure in said container on said valve means.
  • valve has an annular resilient sealing member seating against an annular shoulder defined in the longitudinal bore of said elongated stem member.
  • said portable gas fuel appliance is a portable liquefied propane hand torch.
  • said portable gas fuel appliance is a portable, liquefied fuel appliance.
  • an appliance having a container with a pressurized fluid, means defining a path of fluid flow from the interior of the container through the appliance, and a shutoff valve for interrupting fluid flow through said path
  • the improvement which comprises a pressure reducer and regulator comprising valve means positioned in said path of fluid flow movable to close in a direction against the pres sure in said container, and means resiliently urging said valve means closed with a lesser force than the force exerted on said valve means by the pressure of said pressurized fluid in said container with said shut-off valve open.
