Flow equalization baffle for multi-nozzle spray systems

A nozzle spray assembly which comprises: a spray arm assembly which comprises at least one outlet disposed therein to allow fluid to exit the spray arm assembly; a fluid distribution arm extending from the outlet of the spray arm assembly, wherein the distribution arm comprises an interior surface and a plurality of apertures disposed within the interior surface; and a baffle comprising: (i) a projection portion which extends within the fluid distribution arm a predetermined length, such predetermined length being less than the length of the distribution arm, and the projection portion having a width substantially similar to the cross-section of the interior surface of the distribution arm, thereby forming at least two compartments within the distribution arm wherein a first compartment is formed between a first portion of the interior surface of the distribution arm and a first side of the projection portion without any the apertures disposed within the first compartment, and a second compartment formed between a second portion of the interior surface of the distribution arm and a second side of the projection portion having at least a portion of the apertures disposed within the second compartment; and (ii) a connector portion disposed at an end of the projection portion which is in contact with the outlet of the fluid distribution arm, wherein the connector portion covers at least a portion of the outlet, whereby fluid exiting the outlet into the fluid distribution arm initially enters the first compartment of the fluid distribution arm before entering the second compartment.
