Combustion device

A method of igniting a combustion device having an elongated tube comprising a flame emitting section and a gas receiving section coupled to said flame emitting section, and a nozzle in said gas receiving section for ejecting said gas, said elongated tube having gas ignition means affixed thereto, said gas ignition means being activated by compression, said method comprising:

• encapsulating said ignition means with a cap assembly slidable along said elongated tube;
• supplying a combustible gas to said gas receiving section;
• and
• exerting a force on said cap assembly causing said cap assembly to slide along said elongated tube and contact and compress said ignition means thereby activating the same.

A torch tip comprising:

• a cylindrical forward section terminating in a front end;
• a rearward section for receiving combustible gas and air including fuel jet means having an axial orifice and having an air induction system, the forward end of said rearward section having an axial cylindrical passageway for receiving the air and combustible gas mixture, said passageway having a diameter smaller than the internal diameter of said forward section;
• a middle section, including a generally frustoconical portion, communicatively connecting said forward section to said cylindrical passageway and adapted to provide a Venturi effect;
• ignition means associated with said cylindrical forward section;
• and
• a cap assembly slidable along said rearward section and comprising a base portion having an annular groove and a top portion having a central bore for receiving said rearward section, said cap assembly encapsulating said piezo crystal.
