FIELD: energy.
SUBSTANCE: invention relates to power engineering. Method of ignition in combustion chamber of turbomachine includes fluid inlet phase into chamber through inlet hole, during which piston compresses resilient means under fluid pressure so, that said resilient means are applied force to piezoelectric element sufficient for, that latter caused occurrence of electric voltage between electrodes, which enables formation of electric arc, until piston reaches preset position for closing of valve to seal said inlet opening, and outlet phase of said fluid medium, for which said resilient means push piston back so, that to cause displacement of fluid from said chamber through outlet opening, and said valve opens.
EFFECT: higher efficiency of turbomachine combustion chamber ignition.
