LASER SPARK PLUG Russian patent published in 2018 - IPC H01T13/20 F02P23/04 F02B19/12 

FIELD: power machines.

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 body, insulator, laser microchip installed in the cavity inside the insulator, vacuum tube connected therewith, optical window, focusing lens, prechamber with cylindrical and conical cavities, between the optical window and the prechamber a washer with a hole and the target, installed in one of the prechamber cavities, several outlet openings entering the conical cavity. Target is installed on the shaft with possibility of rotation, and the aerodynamic turbine working blades are attached thereon. Shaft may comprise a conical and cylindrical portions and is made integral with the target. 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.

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.
