FUEL INJECTION VALVE Russian patent published in 2000 - IPC

FIELD: mechanical engineering; internal; combustion engines with compression of mixture and forced ignition. SUBSTANCE: valve has perforated atomizing disk 21. Separating disk 40 is installed behind atomizing perforated disk 21 in direction of flow in longitudinal hole 3 of valve housing 1. Separating disk 40 is installed with minor axial clearance limiting recess 47 in axial direction. Recess executes capillary outwards action onto fuel getting out of atomizing holes 25 in radial direction. Owing to installation of capillary disk 48 between atomizing perforated disk 21 and separating disk 40, capillary effect can be optimized through corresponding contours in capillary disk 48. EFFECT: prevention of formation of deposits and undesirable leaning of fuel air mixture. 10 cl, 2 dwg
