Abstract
In a spray gun for fluids, such as paint, in which an elongated needlenosed plunger is operated by a trigger to move back and forth along the gun barrel for opening and closing a fluid exit opening, the plunger is coupled to the trigger by a ball and socket swivel arrangement to minimize skewing of the plunger while it travels along the barrel.
