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. Solution of this problem was achieved in a laser spark plug containing a housing, a microchip-laser insulator installed in a cavity inside an insulator, connected to it a vacuum tube, optical window, focusing lens, ignition cell with a cylindrical cavity that is converted into a conical, bounded by a conical wall and frontal bottom, washer with a central hole – between the optical window and the ignition cell, several outlets, on the conical wall, that a cylindrical cavity is installed on the inner surface of the cylindrical cavity with a twisting apparatus, and an axial opening is formed on the frontal bottom. Spinning machine can be made with an outer hub. Disc may be formed with an inner surface having a parabolic shape. Laser plug may comprise an additional optical window with a protective cavity between the optical window and an additional optical window. Microchip laser can be installed on a shock absorber. On the insulator, from the side of the inner cavity, a metallized coating may be applied contacting the body. Outlets can be made tangentially.

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.
