Summary: | A fluid injector includes a fluid inlet, a fluid outlet, and a fluid path from the fluid inlet to the fluid outlet. An actuator unit is disposed within the fluid injector. A valve assembly operatively couples to the actuator unit. A spacer member is disposed between a downstream end portion of the actuator unit and a portion of the valve assembly, the spacer member constructed from a compressible, resilient material so as to compress due to expansion forces from fluid in the fluid injector freezing, and to expand when frozen fluid in the fluid injector melts. The spacer member occupies a space in the fluid path of the fluid injector. |
