Abstract: An apparatus for spraying paint in which paint is introduced into the inlet side of a powder-driven pump and the paint or other liquid is maintained above or at approximately 400 psi with power-driven pump. Pressurized paint or other liquid is then accumulated in an accumulator vessel such that, after initial pressurization of the accumulation, the pressure in the accumulator is always greater than or equal to approximately 400 psi during spraying. Communication is effected between the accumulator and a spray head, which head is located remotely from the power-driven pump. The paint or other liquid is throttled through small orifice in the spray nozzle while crating, with the small orifice, a localized pressure of at least 100 psi at the upstream side of the small orifice. The paint or other liquid is discharged through the spray head and directed toward an object to be sprayed, so that the object receives a coating of paint or other liquid via an airless spray.
