Abstract
A method of applying a fluid to a brush is provided. The method includes outputting a flow of fluid from a shaft to an area between the shaft and a distributor where the flow of fluid is restricted by the distributor to generate a uniform pressure buildup inside of the distributor. The method further includes delivering the fluid from the area through at least one opening in the distributor to an outer surface of the distributor where the outer surface of the distributor abuts an inner surface of a housing. The method additionally includes dispensing the fluid from between the outer surface of the distributor and the inner surface of the housing to an outer surface of the housing through at least one perforation in the housing, the housing being attached to a brush. The method also includes applying the fluid through the brush where the fluid is received from the outer surface of the housing. The uniform pressure buildup inside of the distributor enables the brush from end to end to receive an approximate equal amount of liquid.
