Description of the Invention: [Technical Fields of the Invention] This application claims US Patent Application No. 60/971,305, filed on Sep. 11, 2007, and U.S. Patent No. The benefit of the application Serial No. 61/047,482, the contents of which are incorporated herein by reference. [Prior Art] Spray guns for rapidly coagulating materials such as polyurethane foam have conventionally caused difficulty in keeping them clean and properly spraying. Typically, the spray gun is cleaned by partial decomposition and the wetted parts are washed on the solvent. The Graco’s FUSION® spray gun utilizes a grease nipple fitting that allows the grease to be injected into the wet area at the end of the day to prevent the material from hardening therein. SUMMARY OF THE INVENTION A fluid cartridge containing a cleaning fluid is designed to be removably attached to the fluid system by a 1) cylindrical housing, 2) a piston, 3) a vane plug '4) cover, And 5) made of several 0-rings. The cylindrical outer casing has a smooth bore for the low friction piston stroke, at the top for the cover strip, adjacent to the bottom to allow pressurized air to enter the small radial bore below the piston, The top and when inserted into the handle separates the outer 〇-ring of the pressurized air and cleaning liquid, and an outer 〇-ring that seals the pressurized air in the handle at the bottom and when the stomach is inserted. The piston-5-201008660 has two low friction material outer 〇-shaped rings fitted into the groove designed for the smallest 0-ring extrusion, and also has locking fingers, the fingers being the piston When you reach the limit of your trip, bite into position to block the refilling of the fluid. The plug is joined to the bottom of the outer casing to form a hermetic seal and, in the event of a primary joint failure, includes an optional excess ring seal mounted between the plug and the outer casing. The plug has a large flap for easy gripping, and a lug that, when inserted into the handle of the applicator and rotated 90 degrees, latches the fluid when properly pressurized position. After filling the seal in the cleaning liquid, an aluminum foil-inducing inner seal cover is assembled to the fluid port. The foil seal of the fluid cartridge, when inserted, is inserted into the handle of the applicator with a small sharp pin. The piercing system is large enough to allow the cleaning fluid to flow into the applicator when pressurized, but is small enough to limit flow when the handle is removed to prevent inadvertent leakage when depressurized. In the handle of the applicator, pressurized air covers the central portion of the fluid weir and flows through a small radial bore in the outer casing where it is pushed on the bottom of the piston and sequentially in the piston The cleaning fluid is pushed up on the cleaning fluid and pressurized, causing it to flow through the pierced foil seal and into the applicator. The fluid components can be made from a wide range of engineering materials, but for cost reasons, the preferred structure is a plastic injection molding component. The preferred method of joining the plug to the outer casing is spin welding, sonic welding, or adhesive bonding, but it is also possible to mechanically join them, using only the 0-ring of the plug to form the seal. These and other objects and advantages of the present invention will be more fully apparent from the description of the accompanying drawings. [Embodiment] The fluid cartridge 10 containing the cleaning fluid 12 is designed to be removably attached to the spray gun 14. The fluid crucible 10 is made up of a cylindrical outer casing 16, a piston 18, a vane plug 20, a cover 22, and a plurality of serpentine rings. The cylindrical outer casing 16 has a smooth bore for the low friction piston stroke, a thread 16a for the cover 22 at the top, proximate the bottom 10a to allow pressurized air to enter below the piston 18 a small radial bore 16b of fluid, at the top 10b and when inserted into the handle 26 of the spray gun n, separates the pressurized air 28 and the outer 〇-ring 24 of the cleaning liquid 12, and one at the bottom The outer 〇-ring 30 that seals the pressurized air in the handle 26 upon insertion. The piston 18 has two low friction material outer 〇-shaped rings 32 that are fitted into the grooves 18a designed for minimum 〇-type ring extrusion, and also has locking fingers 34, which are the pistons When it reaches its travel limit, it bites into the proper position on the lip 36 to block the refilling of the fluid. The plug 20 is joined to the bottom of the outer casing 16 to form a hermetic seal and, in the event of a primary joint failure, includes a selectively redundant 0-ring mounted between the plug 20 and the outer casing 16. Seal 38. The plug 20 has a large flap 20a and a lug 20b for easy gripping. When inserted into the handle 26 of the applicator 14 and rotated 90 degrees, the lugs are pressurized when the 201008660 is pressurized.匣ι〇 locks in place. After filling the seal in the cleaning liquid 12, an aluminum foil-sensitive inner seal cover 42 is assembled to the fluid port. The foil seal 42 on the fluid raft is threaded into the handle 26 of the applicator 14 by a small sharp pin 44 when inserted. The piercing system is large enough to allow the cleaning fluid 12 to flow into the applicator 14 when pressurized, but is small enough to restrict flow when the handle 26 is removed to prevent inadvertent leakage when decompressing. In the handle 26 of the applicator 14, pressurized air covers the central portion of the fluid crucible 10 and flows through the small radial bore 16b in the outer casing 16, where it is pushed on the bottom of the piston 18 and The cleaning fluid 12 is pushed over the cleaning fluid 12 and pressurized to cause it to flow through the pierced foil seal 42 and into the applicator 14. The fluid components can be made from a wide range of engineering materials, but for cost reasons, the preferred structure is a plastic injection molding component. The preferred method of joining the plug to the outer casing is spin welding, sonic welding, or adhesive bonding, but it is also possible to mechanically connect them, using only the 0-ring 38 of the plug to form the seal. . It is contemplated that various changes and modifications may be made to the fluid without departing from the spirit and scope of the invention as defined by the scope of the following claims.
