Abstract
A manifolded multiple wand spray apparatus with internal cleaning brushes and a flush valve that is activated when the rods carrying the cleaning brushes are rotated is disclosed. Valves that redirect the flow of water away from the manifold for a brief period during which spray orifice cleaning can be accomplished and an air intake valve that will admit air into the manifold to speed the flushing and create a negative pressure in the spray wands so as to draw obstructing materials into the spray wand during flushing is also disclosed.
Claims5
A spray nozzle cleaning apparatus for manifolded spray wand assemblies comprising;
- a) an elongate manifold chamber having a cross sectional area and a liquid introduction port and a multiplicity of shower wands extending laterally from the manifold,
- b) each wand having a cross sectional area, a manifold end and a valve end and at least one spray orifice directed laterally to said wand,
- c) a rotating valve at said valve end of each wand and the rotating valve is provided with a discharge port that has an area that is no larger than 1/N times the cross sectional area of one of the wands where N equals the number of wands extending from said manifold,
- d) a central brush rod secured to said valve and at least one brush secured to said rod and said brush is positioned so that said brush will pass over said spray orifice and said valve is openable and closeable by means of the rotation of said rod,
- e) a means for rotating all the brush rods in all the shower wands in unison.
A spray nozzle cleaning apparatus for manifolded spray wand assemblies comprising;
- a) an elongate manifold chamber having a liquid introduction port and a multiplicity of shower wands extending laterally therefrom,
- b) each wand having a manifold end and a valve end and two diametrically positioned rows of spray nozzels positioned to spray laterally to said wand and each row having a multiplicity of spray nozzles and the nozzles have spray orifices,
- c) a rotating valve at said valve end of each wand and the rotating valve is provided with a discharge port that has an area that is no larger than 1/N times the cross sectional area of one of the wands where N equals the number of wands extending from said manifold,
- d) a central brush rod secured to said valve and a multiplicity of brushs secured to said rod and said brushes are positioned so that said brushs will pass over said spray orifices when said valve is opened and closed by means of the rotation of said rod,
- e) a means for rotating all the brush rods in all the shower wands in unison.
