DETAILED DESCRIPTION OF THE INVENTION

[0013] The objectives and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following description when read in conjunction with the accompany drawings, Wherein:

[0014] FIG. 1: Front view of two plunger high pressure segregated head assembly. 1. Illustrates partitioned segregated head assembly 100 embodying a first embodiment of the present invention. 2. Reference numbers one (1) and two (2) are shown only to illustrate the general location of plungers in commonly used two plunger high pressure pumps.

[0015] FIG. 2: Front view of a two chamber segregated head assembly 100 that provides two individually sourced fluids entirely individual of one another from respective tanks 8, 9 to desired application apparatus (such as a spray nozzle not shown) using a single high pressure pump.

[0016] Referring in greater detail to the drawing of FIG. 2, the head assembly designated 100 comprises a partitioned segregated head assembly creating a separate pressure chamber for each plunger 10. From tank 9 fluid flows through conduit 7 and into check valve 3A, wherein fluid is pressurized and discharged through check valve 2A under high pressure fluid flows through conduit 5 and out to the application apparatus. From tank 8 fluid flows through conduit 6 and into inlet check valve 3B wherein fluid is pressurized and discharged through check valve 2B under high pressure flows through conduit 4 and out to the application apparatus.

[0017] FIG. 3: Front view of a five plunger high pressure head assembly 200. 1. Illustrates partitioned segregated head assembly embodying a second embodiment of the present invention illustrating three segregated chambers. 2. Numbers twenty-one (21), twenty-two (22), twenty-three (23), twenty-four (24) and twenty-five (25) are shown only to illustrate the general location of plungers in common high pressure plunger pumps.

[0018] FIG. 4: Front view of a three chamber configuration segregated head assembly. This configuration is joining three plungers for one chamber providing high pressure rinse. The remaining two plungers are segregated from one another and provide two individual solutions. Numbers twenty-one (21), twenty-two (22), twenty-three (23), twenty-four (24) and twenty-five (25) are shown only to illustrate the general location of plungers in common high pressure plunger pumps.

[0019] Referring in greater detail to the drawings of FIGS. 4 and 5, the head assembly designated 200 comprises a partitioned segregated head assembly configured to provide three separate pressure chambers. Lines 2210 and 2220 designate separation between the three pressure chambers C1, C2 and C3. In this configuration there are five plungers designated 21, 22, 23, 24 and 25 making up three pressure chambers C1, C2 and C3 wherein three plungers 21, 22, 23 are segregated and joined by a manifold 208 therefore combining their respective volumes of fluid to provide one high volume and high pressure rinse. The remaining two plungers 24 and 25 are segregated from one another as denoted by lines 2210 and 2220 and provide two high pressure solutions completely individual of one another from respective tanks to desired application apparatus.

[0020] In operation, fluid from tank 214 flows through conduit 209 to inlet manifold 208 joining inlet check valves 203A, 203B, 203C wherein fluid is pressurized and discharged out the discharge check valves 202A, 202B, 202C respectively and joined by manifold 207 then out through conduit 206 to desired application apparatus. Simultaneously fluid from tank 213 flows through conduit 210 to inlet check valve 203D wherein fluid is pressurized then discharged out the discharge check valve 202D through conduit 205 then out to desired application apparatus. Simultaneously from tank 212 fluid flows through conduit 211 to inlet check valve 203E wherein fluid is pressurized and discharged out the discharge check valve 202E out through conduit 204 then out to desired application apparatus. Conduits 204, 205, 206, 209, 210, 211 are not of any specific shape or material. A single high pressure pump is operatively connected to the segregated head assembly and check valves 202D, 202E, and 202A, 202B and 202A are individually actuated to direct selected fluid to the desired application apparatus.
