Patent ID: 8464735

Claim:
A solution injection bar, comprising: a substantially rigid bar comprising a pair of spaced apart outer walls terminating at substantially opposite ends in a pair of spaced apart terminal end portions with a lengthwise upper edge portion extended between the terminal end portions and a substantially planar lengthwise lower edge surface spaced apart therefrom and extended between the terminal end portions and defining an elongated and substantially planar cleaning head operating surface; an elongated upper cavity formed interior of the bar adjacent to the lengthwise upper edge portion thereof and defining an elongated upper solution distribution and pressure equalization chamber that is arranged in fluid communication with a solution inlet orifice for receiving there through a flow of pressurized liquid cleaning solution, the elongated upper cavity further comprising a length dimension, a height dimension and a depth dimension with the length dimension being significantly greater than the height dimension; a cleaning solution flow restrictor formed interior of the bar, the cleaning solution flow restrictor being substantially contiguous with the upper cavity between the spaced apart terminal end portions of the bar; and an elongated lower solution discharge chamber formed interior of the bar adjacent to the substantially planar lengthwise lower edge surface thereof and substantially contiguous with the cleaning solution flow restrictor between the spaced apart terminal end portions of the bar for receiving the liquid cleaning solution from the elongated upper cavity, the elongated lower solution discharge chamber being further positioned for delivering the received liquid cleaning solution to the cleaning head operating surface in a substantially uniform pressurized flood through an elongated cleaning solution discharge slot formed substantially contiguous with the elongated lower solution discharge chamber substantially opposite from the cleaning solution flow restrictor and adjacent to the lengthwise lower edge surface and arranged in fluid communication with the cleaning head operating surface.
