What occurs when you release the trigger on a gravity feed spray gun?

When you release the trigger on a gravity feed spray gun, the process is reversed. This means that the mechanism controlling the paint flow is disengaged, which stops the paint from being dispensed. The trigger is responsible for controlling both the paint and air supply; thus, when the trigger is released, the air valve system essentially ceases to push paint out of the fluid tip. Additionally, the release of the trigger also allows the paint to stop flowing, preventing any excess or undesirable splatter. Understanding this function is crucial for proper operation and control over the painting process.

The incorrect options may suggest misunderstandings of the spray gun's operation. For instance, stating that the fluid tip opens wider would imply that releasing the trigger increases paint flow, which contradicts the fundamental operation of the gun. Saying that the air valve system stops regulating air might imply that it continues to function improperly after the trigger is released. Meanwhile, noting that paint continues to flow freely would suggest an inability to stop overspray or drips when the trigger is not engaged, which is not the intended function of the spray gun.
