Claims

[Scope of utility model registration request]

Conductive cylindrical bodies 2 and 3 having an inner and outer heavy structure are electrically insulated from each other and have a cutting oxygen flow path 32 in the center and a mixed gas flow path 1 of preheating oxygen and combustible gas on the outer periphery. is,
It has a crater a with spark electrodes 4 and 5 formed at its tips, and flow passages 17, 21, 15, and 16 that communicate with the respective flow passages 32 and 1 of this crater a, and the crater a
In the cutting oxygen flow path 21 at the rear of the crater a, there are piezoelectric mechanisms 6, which collide with each other and generate an electromotive force due to the cutting oxygen pressure. 7 and the piezoelectric mechanisms 6, 7, an actuator pull-back mechanism 8 using a magnet is incorporated, which returns the member (7 or 6) on the side that moves due to the cutting oxygen pressure to the standby position and holds the position. Electrode 6 of piezoelectric mechanism 6, 7
A, 6B and the spark electrodes 4, 5 are electrically conductively connected to each other in an automatic ignition type gas cutting torch, in which the movable member (7 or 6) and the member 22 that comes in contact with the movable member (7 or 6) when it is in the standby position. An automatic ignition type gas cutting torch is provided with a pressure relief passage 9 that communicates a flow passage 17 portion upstream near the contact surface with a flow passage 21 portion downstream of the contact surface.
