DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(11) Referring now to the drawings, the present invention is a solenoid high pressure indexing valve system, and is generally referred to with numeral 10. It can be observed that it basically includes at least one solenoid manifold assembly 20 and power supply assembly 120.

(12) As seen in FIGS. 1 and 2, solenoid manifold assembly 20 comprises manifold assembly 30 and a plurality of solenoid valve assemblies 80. Manifold assembly 30 comprises top face 32, first and second lateral faces 34 and 35, inlet tube face 36, and sensor face 38. Inlet tube face 36 is opposite to sensor face 38. Manifold assembly 30 further comprises pressure sensor 68. In a preferred embodiment, manifold assembly 30 is rectilinear in shape. The shape and features of manifold assembly 30 may change based upon the ultimate or intended method of manufacture, and total number of outlet passages 58 and 60, seen in FIG. 5. These features might include material savers, parting lines, machined surfaces, datum pads for plastic injection molding, metal casting, etc. Solenoid manifold assembly 20 is a fully expandable electro-mechanical pressure-triggered valve with a single inlet tube 64 and multiple outlet tubes 66 used to dispense fluids from a single or centralized fluid supply location to multiple other locations.

(13) As seen in FIG. 3, top face 32 comprises a plurality of bores 40. In one embodiment, top face 32 comprises eight bores 40 comprising eight solenoid valve assemblies 80 respectively.

(14) Inlet tube face 36 comprises inlet hole 42, seen in FIG. 4, and sensor face 38 comprises sensor hole 44. First lateral face 34 comprises a plurality of lateral holes 46, and second lateral face 35 comprises a plurality of lateral holes 48, seen in FIG. 4. In this embodiment, first lateral face 34 comprises four lateral holes 46 and second lateral face 35 comprises four lateral holes 48, as seen in FIG. 4. Manifold assembly 30 further comprises couplings 62. Solenoid valve assembly 80 comprises valve body 82, valve head 84, valve base 86, and connectors 88.

(15) As seen in FIG. 4, solenoid valve assemblies 80 are mounted onto manifold assembly 30. Manifold assembly 30 further comprises inlet tube 64, and a plurality of outlet tubes 66. Inlet tube 64 is positioned into inlet hole 42 with coupling 62, and pressure sensor 68 is positioned into sensor hole 44 at an opposite end. The features required to attach coupling 62 and pressure sensor 68 reside at their respective ends. Outlet tubes 66 are positioned on lateral holes 46 and 48 respectively with couplings 62. The features required to attach couplings 62 reside at each of respective lateral holes 46 and 48.

(16) As seen in FIGS. 5 and 6, manifold assembly 30 further comprises inlet passage 56 and a plurality of outlet passages 58 and 60. Inlet passage 56 and outlet passages 58 and 60 are punctured in manifold assembly 30 to provide connections for fluid between different areas of manifold assembly 30. Inlet passage 56 is relatively centered internally through manifold assembly 30 and extends from inlet hole 42 to sensor hole 44. Inlet passage 56 comprises input passages 50. In a preferred embodiment, an array of orthogonal segmented intersecting outlet passages 58 and 60 are drilled in manifold assembly 30. Outlet passages 58 and 60 are equally spaced internally along the length of manifold assembly 30 and are perpendicular to inlet passage 56. Outlet passages 58 and 60 end on respective lateral holes 46 and 48. Solenoid manifold assembly 20 may function in any orientation as solenoid valve assemblies 80 are not sensitive to small pressure differentials, for example, due to distance between inlet hole 42 and far-most outlet passages 58 and 60, as the input pressure is of a magnitude higher than the differential pressures between inlet passage 56 and solenoid valve assembly 80.

(17) As seen in FIG. 7, each solenoid valve assembly 80 further comprises interior top wall 90, spring 92, solenoid coil 94, and valve seal 96. Bores 40 comprise valve base 54 and inlet-outlet passages 52. Bores 40 and inlet-outlet passages 52 are drilled into manifold assembly 30 to attach and engage solenoid valve assemblies 80. Inlet-outlet passages 52 are connected with input passages 50 and respective outlet passages 58 or 60. Present invention 10 uses the plurality of solenoid valve assemblies 80 mounted onto manifold assembly 30 to dispense fluid from inlet passage 56 to the plurality of outlet passages 58 and 60.

(18) As seen in FIG. 8, power supply assembly 120 comprises at least one controller 122, power supply 124, and wires 126, 128 and 130. Each solenoid valve assembly 80 and pressure sensor 68 are connected to controller 122. Wires 126 connect each solenoid valve assembly 80 to controller 122. Wires 128 connect controller 122 to power supply 124. Wires 130 connect pressure sensor 68 to controller 122. A default state of entire solenoid manifold assembly 20 is closed. Solenoid valve assembly 80 is spring-biased in a normally closed state and only opens when a voltage differential is applied across connectors 88, as seen in FIG. 1. Controller 122 manages the sequence in which each solenoid valve assembly 80 is opened/closed.

(19) Power supply 124 provides sufficient voltage and current capacity to operate controller 122. Power supply 124 may be any power source such as, but not limited to, in the form of an AC line, DC battery, solar, etc., depending on size constraints of controller 122. In another embodiment, power supply 124 might be integrated directly into controller 122. In one embodiment, present invention 10 comprises a single solenoid manifold assembly 20 connected to controller 122 and power supply 124. In this embodiment, upon actuation of a remotely located pump or pressure source, pressure sensor 68 senses either a rise or fall in pressure and then signals controller 122 to open a next solenoid valve assembly 80 in sequence.

(20) As seen in FIG. 9, in another embodiment, a plurality of solenoid manifold assemblies 20 may be connected together, whereby inlet tubes 64 are parallel while outlet tubes 66 are sequential. In the illustrated embodiment, present invention 10 comprises four solenoid manifold assemblies 20 with eight outlet tubes 66 per manifold assembly 30. One solenoid manifold assembly 20 can be used as a master solenoid valve assembly 20, and additional solenoid manifold assemblies 20 would be designated as slave solenoid valve assemblies 20. Pressure sensor 68 is connected to the master solenoid valve assembly 20 and plugs 150 are positioned on remaining sensor holes 44 to obstruct the flow of fluid in the remaining three slave solenoid valve assemblies 20. Multiples solenoid manifold assemblies 20 may be connected together, but only the master solenoid manifold assembly 20 needs pressure sensor 68, and the remaining slave solenoid manifold assemblies 20 use plug 150 in place of pressure sensor 68.

(21) In operation, an overall cycle begins at the master solenoid valve assembly 20. After a master controller 122 cycles through all of solenoid valve assemblies 80 in respective manifold assembly 30, the master controller 122 will pass control to the first slave controller 122 and then cycle through its respective solenoid valve assembly 80. After all of the slave controllers 122 cycle through their own arrays of solenoid valve assemblies 80, control will be passed from the last slave controller 122 back to the master controller 122 and the overall cycle will repeat. The pressure that triggers controller 122 to open solenoid valve assemblies 80 comes from a remotely located pump or other pressure source. Present invention 10 may work at high or low pressures. However, in a preferred embodiment, present invention 10 is a high pressure/low volume system. Additional slave solenoid manifold assemblies 20, each with their own slave controller 122, may be added to present invention 10 by teeing into supply inlet tube 64. Additional inlet tubes 64 may be connected by 4-way coupling 140 and T-way coupling 142.

(22) Each solenoid manifold assembly 20 requires its own controller 122 to sequence each solenoid valve assembly 80. Wires 126, 128, and 130, as seen in FIG. 8, are required to provide power to slave controllers 122. The optimal configuration for system layout would be to maintain close proximity for all of solenoid manifold assemblies 20. In a preferred embodiment, present invention 10 serves as a delivery system in general for hydraulics and pneumatics, and particularly for misters, foggers, spray systems, and the like. Present invention 10 creates multiple sequential pathways without significant loss, and is exponentially expandable.

(23) The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
