Pulsater fluid system flusher

An apparatus for cleaning fluid lines comprising

• a hose for carrying cleaning liquid and air to said fluid lines,
• means for supplying cleaning liquid and air to said hose for cleaning said fluid lines, comprising,
• a source of compressed air,
• an enclosed tank having a reservoir partially filled with cleaning liquid,
• an air and liquid manifold means operatively connected to said air source and to said tank,
• said manifold means comprising an air flow system and a liquid distribution system, said air flow system having an air valve interconnecting said source of compressed air with an air chamber openly communicated with an upstream air passage and with a downstream air passage for simultaneously flowing compressed air therein, said upstream air passage having a predetermined restricted sized orifice openly communicating with said tank for restricting the flow of compressed air therein to gradually increase the air pressure in said tank, said downstream air passage openly air flowingly connecting with a hose barb means having an oval rear channel section integral with a restricted diameter sized oval front channel section,
• said liquid distribution system having a vertical liquid supply tube descending into said liquid for passing cleaning liquid to an upwardly connected downstream liquid passage having a liquid control means disposed therein which controls the flow of liquid through an interior tube extending from said downstream liquid passage longitudinally within said downstream air passage and said rear oval channel section and within said front channel section terminating at the tip end of said interior tube partway within said front channel wherein the cleaning liquid passes from said tip end into said front channel section,
• the exterior surface of said interior tube exposed to an open passage of air flowing through said downstream air passage and said rear channel section and a restricted passage of air flowing to its tip partway within said front channel section, where the air flow encounters said cleaning fluid passing from said tip into said rear channel section,
• said front channel section of said hose barb means connected to said hose for passing a mixture of cleaning liquid and pressurized air into said hose.
