LASER IGNITER Russian patent published in 2018 - IPC F02B19/12 F02P23/04 H01T13/40 

FIELD: machine building.

SUBSTANCE: invention relates to power machines, specifically to laser spark plugs with an ignition cell, and can be useful in transport and heat power engineering. Laser spark plug contains a housing, microchip-laser insulator installed in the cavity inside the insulator, vacuum tube connected to it, optical window, focusing lens, ignition cell with a cylindrical cavity, passing into a conical, bounded by a conical wall and frontal bottom, washer with a central hole – between the optical window and the ignition cell and target installed in the cavity of the ignition cell and fixed by means of a holder on the frontal bottom, several outlets, on the conical wall, inside the cylindrical cavity, two rotors of the birotate gas turbine are rotatable in opposite directions, with one impeller mounted on the inner surface of the cylindrical cavity, and the other on the holder.

EFFECT: technical effect: an increase in the service life of the laser spark plug by preventing contamination of the optics and the laser beam outlet.
