Abstract

A spray head for a fluid distribution system may include first and second deflector inner surfaces defining a fluid outlet. A piston may define a variable orifice communicating with the fluid outlet to control fluid flow through the spray head. An inner surface of the second deflector may define a grooveless deflector central region disposed between first and second deflector lateral regions. Each of the first and second deflector lateral regions may include at least a first deflector groove extending along a first deflector groove path oriented substantially radially relative to the inlet passage, so that the spray head generates a spray pattern having more uniform fluid distribution across the spray pattern.
