DRIVE
July 8, 2015
The invention relates to a fuel injector (10) with an injector housing (11) which forms a high-pressure chamber (30) connectable to a high-pressure source (33), in which an injection valve member (13) is arranged so as to be movable in stroke motion. According to the invention, it is provided that the high-pressure chamber (30) is bounded at least partially by two elements (16; 16a; 16b, 17; 17a), an inner first, sleeve-shaped element (16; 16a; 16b) with a first recess (52; 52a) arranged in the first element (16; 16a; 16b) for forming the high-pressure chamber (30), and a second element (17; 17a) immediately surrounding the first element (16; 16a; 16b) with a second recess (53; 53a), wherein the second recess (53; 53a) surrounds the first element (16; 16a; 16b) on its outer peripheral surface (51), and wherein the second element (17; 17a) is connected to the first element (16; 16a; 16b) while forming a radially acting pressure force on the first element (16; 16a; 16b).
