Liquid Intrusion Sealing Structure Of A Urea Injector |
| 摘要 |
A fluid injector includes a body associated with an outlet of the injector. An inlet tube is coupled to the body and has an open end for receiving fluid to be injected. An inlet cup has an open end and covers the open end of the inlet tube and also covers a portion of the body. The injector includes sealing structure including a primary seal providing a seal between the inlet cup and the inlet tube, a secondary seal between the body and the inlet cup and constructed and arranged to prevent liquid that is external to the injector from entering an interior of the injector through the open end of the inlet cup, and a surface feature on the body or on the inlet cup constructed and arranged to compress a portion of the secondary seal between the inlet cup and the body. |
