FIELD: process engineering.
SUBSTANCE: invention relates to production of throttling sections, first of all, in fluid bypass channels in fuel atomiser control valve. First, channel (14) is made in part (10) to form the profile of throttling section (32). Then, sharp-edge transition (44) is formed ahead of throttling section (32). Then, throttling section (32) is subjected to electroerosion processing to get the preset diameter (54). Note here that throttling section formed outlet part (38) is preserved.
EFFECT: whatever location of orifices with cavitation source.
10 cl, 6 dwg
