ABSTRACT:
A gas fuel torch assembly is provided for attachement to a portable pressurized gas fuel cylinder. The assembly includes a housing and a gas delivery system in the housing. The system delivers gas fuel from the cylinder within an adjustable operating pressure range to a burn tube connected to the housing. The gas delivery system includes a gas passageway, an on/off valve and a pressure regulator valve assembly. The pressure regulator valve assembly includes a regulator body slidably received in the housing and an adjustable regulator valve stem. A metering orifice provided in the gas passageway of the regulator body defines a maximum pressure at which gas fuel is fed into the burn tube. Both the on/off valve and regulator valve include spring biased resilient ball members loosely held within enlarged valve chambers.
