Claims

[Claims for Utility Model Registration] ■ A state in which a conductive inner cylinder 1 and an outer cylinder 2 each having a spark electrode 3.4 at their front end are interposed with an electrical insulating material 5 behind the spark electrode 3.4. 1 on the outer circumferential surface facing the electrical insulating material 5 at the front end portion of the inner cylinder 1. A plurality of groove-shaped mixed gas flow paths 6 along the axial direction are formed in the circumferential direction, and the plurality of mixed gas flow paths 6 are formed at a position corresponding to the front part of the electrical insulating material 5.
A spark ignition type crater in which an annular flow path 10 is formed that communicates with the group at their outlet sides. (2) The spark ignition type crater according to claim 0, wherein the annular flow path 10 is formed by cutting the inner circumferential surface of the electrical insulating material 5. (2) The spark ignition type nozzle according to claim 0, wherein the annular flow path 10 is formed by cutting out the tip of the groove-shaped mixed gas flow path 6 at the front end of the inner cylinder 1. (2) The annular flow path 10 is formed by cutting off the inner circumferential surface of the electrical insulating material 5 and cutting off the tip of the groove-shaped mixed gas flow path 6 at the front end of the inner cylinder 1. The spark ignition type crater described in scope item 0. (2) The spark ignition type crater according to claim 0, wherein the electric insulating material 5 is made of ceramic.
