High-pressure injector

A high-pressure injector having the following assemblies:

• an injector unit (1),
• a drive unit (2) situated adjacent the injector unit (1) for driving the injector unit (1),
• a high-pressure connection (4), and
• a high-pressure storage unit (3) situated between the high-pressure connection (4) and the drive unit (2), on a side of the drive unit (2) opposite the injector unit (1), for supplying the injector unit (1) with fuel, wherein
• the high-pressure injector has a housing (5) in which a plurality of the named assemblies (1, 2, 3) are arranged behind one another in the longitudinal direction of the injector,
• the housing (5) completely envelops at least a first named assemble, in particular the drive unit (2) and/or the high-pressure storage unit (3),
• at least one of the named assemblies has cut-outs (13) in one of the contact zones (7) between adjacent (2,3) enveloped by the housing (5), to increase the contact pressure, and
• the cut-outs (13) are configured symmetrically to a longitudinal axis of the high-pressure injector.

A method for manufacturing a high-pressure injector having

• a drive unit (2) situated adjacent an injector unit (1) for driving the injector unit (1),
• a high-pressure storage unit (3) situated between a high-pressure connection (4) and the drive unit (2), on a side of the drive unit (2) opposite the injector unit (1), for supplying the injector unit (1) with fuel, said method comprising the steps of:
• arranging the injector unit (1), the drive unit (2), the high-pressure storage unit (3) and the high-pressure connection (4) behind one another in a longitudinal direction of the injector and aligning and pressing the same together;
• and
• arranging a housing (5) around the previously aligned and pressed injector unit (1), drive unit (2) and storage unit (3) so that the housing (5) completely envelops at least the drive unit (2) and/or the high pressure storage unit (3).
