Description: |
| The key feature of the injector is the entire functional core is a single piece which can easily be removed and replaced. The patent is also of interest because it includes a special purpose wrench with two box ends and side screwdriver.
Finally, it is of interest because the specifications note it had already received British, French, and Belgian patents. |
