FIELD: engines and pumps.
SUBSTANCE: coaxial spray injector includes a housing with a hollow tip, in the outlet part of which there are radially located slots made in the form of alternating projections and cavities, and attaching the oxidiser cavity to combustion zone, a sleeve enveloping the tip with a gap and attaching the cavity of the main fuel to combustion zone; radially located slots are made so that perimetre of central part of the jet, which is restricted with generatrixes of beams, is not more than 3s, and beam length is 2.3…2.5s, where s is beam thickness; number of beams is equal to three; in the sleeve between projections of the tip there made are channels, the outlet part of which opens to combustion zone, and the inlet part is connected to additional fuel cavity.
EFFECT: possibility of using and injector as a three-component injector with improved completeness of mixture formation.
