摘要： A fluid injector comprises an actuator unit, a cartridge, which comprises a recess, which on one of its open ends forms an injection nozzle and takes in a needle. The needle comprises a first and a second part (15, 17). The first part (15) is inserted into the recess and closes or opens the injection nozzle depending on the position of the first part (15). The second part (17) is coupled to the actuator unit on one of its free ends and is coupled to the first part (15) via a coupling unit. The coupling unit is arranged in positive connection to the first part (15) and is joined to the second part. In that way the material for the first part may be chosen for being highly wear resistant. On the other hand the material of the second part (17) may be chosen for being well-suited for a joining process.

摘要： A fluid injector comprises a housing (1), a valve body (2) and an actuator unit (3) that is inserted into the housing (1). The valve body (2) comprises a cartridge (21) with a recess (211) that takes in a needle (22). The valve body further comprises a hollow body (23) which is arranged in a fixed position to the needle (22) and forms a first spring rest (231). The valve body further comprises a valve cap (26), which takes in the cartridge (21) and forms a second spring rest (261). A return spring (25) rests on one hand on the first spring rest (231) and on the other hand on the second spring rest (261). The valve cap (26), the housing (1) and the cartridge (21) are formed such, that before the valve cap (26) and the housing (1) and the valve cap (26) and cartridge (21) are permanently fixed to each other the valve cap is moveable relative to the housing (1) and the cartridge (21) while the housing (1) and the cartridge (21) stay in a fixed position relative to each other.
