Abstract
An injector includes a nozzle portion to inject fluid, a coil to generate a driving force to open and close the nozzle portion, and a molded resin that seals the coil. A cooling jacket has a flow path to cause cooling fluid to flow therethrough. The cooling jacket houses the injector and has an opening in an end opposite to the nozzle portion. A sealing material is filled in a space between the cooling jacket and the molded resin.
Claims9
A fluid injection device comprising:
- an injector that includes:
- a nozzle portion configured to inject fluid;
- a coil configured to generate a driving force to drive the nozzle portion to open and close the nozzle portion;
- and
- a molded resin that seals the coil;
- a cooling jacket that has a flow path configured to cause cooling fluid to flow therethrough, that houses the injector, and that has an opening in an end opposite to the nozzle portion;
- and
- a sealing material that is filled in a space between the cooling jacket and the molded resin, wherein
- the sealing material covers an end of the molded resin opposite to the nozzle portion, and
- the sealing material is exposed to the opening.
