Modular multiple-fluid component selection and delivery system

DETAILED DESCRIPTION The purpose of the present invention is to provide a simple, uncomplicated, modular, multiple-fluid component selection and supply system.
The present invention provides a plurality of manifolds or blocks which can be stacked end to end to provide a plurality of fluid component selection valves.
The system is simple in construction and allows a simple method for adding aa many additional valves to increase the multiple fluid components as needed.
Each block has a main passageway and two secondary passageways intersecting the main passageway.
The main passageway exits at planar ends of the block while the secondary passageways exit at the sides.
Bores passing through the blocks perpendicular to the supply passageways permit installation of plug valves to control the flow of the paint or fluid components in each passageway.
The output end of each main passageway in each block is threaded for installation of a main hose fitting or connection.
The blocks can be stacked by simply placing them end to end and with an alignment sleeve inserted between the transition of the main passageway from one block to the next successive block and securely clamping them together with an appropriate length stud.
An O-ring in the planar face of each respective block seals the transition from the main passageway in one block to the main passageway in the next successive block.
Each block has a small hole passing entirely through the block parallel with the main passageway for securing and clamping the respective blocks in a stacked arrangement with the stud.
The stud length is changed to accommodate added blocks to provide for delivery and control of additional fluid components.
As many blocks as needed can be connected end to end in a stacked arrangement to provide control of any number of fluid components.
The bores for the plug valves are placed in the secondary passageways as close as possible to the main passageway to minimize paint loss during cleaning of the system.
This system permits easy conversion from one color to another by simply turning off one valve and purging the system by operation of the valve in the main passageway to clean the main passageway and a spray gun attached thereto by a suitable hose
