Abstract (en)
[origin: WO2022012805A1] The invention relates to a component (3), in particular fluid distributor (2), for an injection system (1) for mixture-compressing, applied-ignition internal combustion engines which apportions a fluid which is under high pressure, having a main part (14) and at least one connection piece (16A-19A) formed on the main part (14) which connects an injection valve (7-10), wherein the injection valve (7-10) can be inserted into a receiving chamber (27-30) of the connection piece (16A-19A) along an assembly axis (40-43) during assembly, wherein at least the main part (14) and the connection piece (46-49) are formed by single or multi-stage forging and wherein a recess (51, 51') is formed on an outside (52, 52') of the connection piece (46-49), into which, in an assembled state, an orientation element (50) of the injection valve (7-10) engages in order to restrict a degree of freedom of rotation of the injection valve (7-10) about the assembly axis (40-43). According to the invention, the connection piece (16A-19A) is reworked after forging such that at least one lateral face (56, 57, 56', 57') of the recess (51, 51') of the connection piece (16A-19A) on which, in the assembled state, in order to restrict a degree of freedom of rotation in a selected rotation direction (49) about the assembly axis (40-43), a contact between the orientation element (50) of the injection valve (7-10) and the connection piece (16-19A) is enabled, is designed at least approximately having a specified side height (58). Furthermore, the invention relates to an injection system having such a component (3) and to a method for producing such a component (3).
