    摘要: A fluid injector has a housing (1) comprising a housing recess (3) taking in an actuator unit and a valve body (9) being coupled to the housing (1) and being penetrated by a valve body recess (11) in axial direction. The valve body recess (11) takes in a needle (13), which prevents in a closing position a dosage of fluid and enables the dosage of fluid apart from the closing position. The actuator unit comprises a solid state actuator (23) being taken in an actuator housing comprising an actuator tube (25) consisting along an axial extension of the solid state actuator (23) of aluminum titanate. The solid state actuator (23) is arranged such, that it acts on the needle (13). The actuator tube (25) is fixed to the valve body (9).

    摘要: A Compensation assembly (30) for an injector comprises a cup shaped compensation assembly body (32) having a bottom portion (34) and a recess (33). A piston (36) is arranged in the recess (33) of the cup shaped compensation assembly body (32) movable in axial direction. A first fluid chamber (44) is bordered in axial direction by a first side (37) of the piston (36) and by the bottom portion (34) of the cup shaped compensation assembly body (32). A second fluid chamber (46) is bordered in axial direction by a first membrane (35) and by a second side (39) of the piston (36) facing away from the first side (37) of the piston (36). A fluid path extends from the first to the second fluid chamber (44, 46). An elastic compensation device is checklessly hydraulically coupled to the second fluid chamber (46).

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.

    摘要: A fluid injector comprises a housing, an actuator and a valve body. The valve body has a cartridge (21) with a recess, that forms an injection nozzle on one end, and with a needle (22), that is arranged in the recess and closes the injection nozzle, if it rests with its seat area (224) on a needle seat (215) of the cartridge (21). The area (216) of the cartridge (21) adjacent to the needle seat (215) has a cylindrically-shaped outer contour and the needle (22) has a cylindrically-shaped area (223) adjacent to the seat area (224). The area (216) adjacent to the needle seat (215) and the cylindrically-shaped area (223) have the same diameter.
