What is the purpose of an air eliminator in a nozzle line assembly?

The air eliminator in a nozzle line assembly serves the purpose of avoiding nozzle drip on shut down. When the nozzle is shut off, the remaining fuel in the nozzle line could potentially drip out if air is trapped in the line. The air eliminator works to remove any air that could cause this unwanted dripping, ensuring that the fuel flows smoothly and completely out of the nozzle when it is turned off. This helps maintain cleanliness and efficiency, as it prevents fuel waste and minimizes the risk of spills or staining from drips.

In the context of this function, reducing noise, preventing fuel leakage, or increasing fuel pressure are not the primary roles of an air eliminator. While these aspects may be relevant to other components or considerations in a nozzle assembly, the specific role of the air eliminator is to manage the air within the fuel lines to mitigate drips at shut down.
