초록 ▼

A portable gas hand torch igniter and burner assembly of the piezoelectric-type to be assembled onto a portable pressurized gas fuel cylinder which includes a handgrip housing body having an internal cavity gas conduit network, and an elongated burn tube having a venturi portion at its inlet end and an end-tapered orifice cylinder removably mounted in the venturi portion. A gas pressure regulator valve mechanism maintains a substantially constant predetermined gas supply pressure level at the inlet portion of said gas conduit network and a control valve associated with a push button normally closes the conduit network against passage of gas to the burn tube. A piezoelectric igniter in said housing body is actuated by inward depression of the push button to open the control valve to admit gas to the burn tube and generate a spark-producing voltage a predetermined short interval after opening of the control valve to produce a spark within the burn tube.

A portable gas hand torch igniter and burner assembly of the piezoelectric-type to be assembled onto a portable pressurized gas fuel cylinder, comprising a handgrip housing body having upper and lower cavities opening through top and bottom wall portions thereof respectively and an interconnecting gas conduit network therebetween, the lower cavity forming an internally threaded gas inlet to be threaded onto the neck of the fuel cylinder for rigidly mounting the housing body thereon, an elongated burn tube having a venturi portion at its inlet end and an end-tapered orifice cylinder removably mounted in the venturi portion, means removably supporting said venturi portion and orifice cylinder in said upper cavity for rigidly mounting the burn tube on said housing body, a gas pressure regulator valve mechanism adjustably supported in said lower cavity for maintaining a substantially constant predetermined gas supply pressure level at the inlet portion of said gas conduit network, means forming a valve chamber intercepting said gas conduit network having a control valve therein normally closing the conduit network against passage of gas to the burn tube, a push button on the housing body supported for rectilinear axial movement along an axis intercepting the control valve from a normal outward position projecting from the housing body, piezoelectric igniter means in said housing body having a case portion movable along said axis responsive to inward depression of said push button for opening said control valve to admit gas to the burn tube and having a plunger portion movable relative to its case portion responsive to such push button depression to activate the igniter to generate a spark-producing voltage a predetermined short interval after opening of the control valve, an electrode means extending from the igniter to a location within the burn tube near its exit end forming a spark gap with the burn tube for igniting the gas admitted thereto upon opening of said control valve.
