| 摘要 |
The invention relates to an injector comprising an actuator, a valve (26) and a nozzle. The actuator body (22), the valve body (50) and the nozzle body are rigidly interconnected in a coaxial stack by means of an injector nut. The injector also comprises a device (92) for coaxially positioning the actuator body (22) and the valve body (50). The positioning device (92) comprises a radial positioning means (94) which prevents the actuator body (22) and the valve body (50) from moving out of alignment, and an angular positioning means (96) which prevents the same two bodies (20, 50) from rotating relative to one another, the two positioning means (94, 96) being separate from and independent of one another. |
