Water straining and chemical additive device for marine vessels and recreational vehicles

An additive injection and straining device, the device comprising:

• a filter body having a wall inflow surface, a central aperture, and a peripheral aperture;
• a return water tube coupled to the filter body, wherein the return water tube;
• comprises a tube outflow surface and a tube inflow surface;
• an inflow conduit for receiving the fluid, wherein the inflow conduit is in fluid communication with the peripheral aperture, and wherein the inflow conduit is formed by the wall inflow surface and the tube inflow surface;
• an inflow filter screen coupled to the peripheral aperture;
• a filter cap coupled to the filter body, wherein the filter cap forms a primary cavity;
• a limiter forming a secondary cavity, wherein the secondary cavity is in fluid communication with the central aperture and the peripheral aperture;
• a mixing aperture disposed in the limiter, wherein the mixing aperture provides fluid communication between the primary cavity and the secondary cavity;
• an outflow filter screen coupled to the central aperture;
• and
• an outflow conduit for releasing the fluid from the device, wherein the outflow conduit is in fluid communication with the central aperture, and wherein the outflow conduit is formed by the tube outflow surface.
