Abstract
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.
