 which axes is disposed at a given turning angle to the longitudinal axis. The suction side of each vane is spaced-apart from a juxtaposing pressure side of an adjacent vane to define a corresponding one of a plurality of aligned air flow channels therebetween.
In operation, a fuel flow is directed through the inner fuel passage with atomizing air flow being directed through the flow channels of the outer air passage. Fuel is discharged into the combustion chamber of the engine from the first discharge orifice and as a generally annular sheet, with atomizing air being discharged from the second discharge orifice flow as a surrounding swirl which impinges on the fuel sheet. As a result of the uniform velocity profile developed in the swirl by the effect of the aerodynamic turning vanes, the sheet is atomized into a spray of droplets of more uniform size.
The present invention, accordingly, comprises the apparatus and method possessing the construction, combination of elements, and arrangement of parts and steps which are exemplified in the detailed disclosure to follow. Advantages of the present invention include an airblast or air-assisted nozzle construction which provides for a reduction in the mean droplet size in the liquid spray, and which utilizes less atomizing air to effect a specified droplet size. Additional advantages include an airblast or air-assisted nozzle which provides consistent atomization over a full range of turning angles and a wide range of engine operating conditions.
These and other advantages will be readily apparent to those skilled in the art based upon the disclosure contained herein. 1. Field of the Invention

Reciprocating piston-type pumps for spray painting equipment are generally known and disclosed, for example, in the Snetting et al. U.S. Pat. No. 5,316,445. Pumps of this type include a housing with inlet and outlet ports in communication with a paint-pumping chamber. The inlet port is configured to be fluidly connected to a source of paint, while the outlet port is configured to be fluidly connected to a paint spray gun. A piston assembly is mounted for reciprocal motion within the paint-pumping chamber, and is driven by a motor. During operation of the pump, paint is drawn into the paint-pumping chamber through the inlet port. Paint within the paint-pumping chamber is then pressurized by the piston assembly and forced out through the outlet port to the spray gun.
