Filter assembly with a hollow perforated body
First Claim
1. A filter assembly for removing suspended matter from a fluid, said assembly comprising:
- a container, said container having a base, a lid and at least one wall therebetween, said container having an interior surface and an exterior surface, and said container having an inlet aperture and an outlet aperture;
a filter screen comprising a hollow perforated body, said body having an open end and a closed end, and said open end having a peripheral edge, and said body having an axis passing through the center of symmetry of said open end and the center of symmetry of said closed end, said filter screen being inserted within said container such that said open end of said filter screen is proximal to said base and said closed end of said filter screen is proximal to said lid;
a conduit having a first open end and a second open end, said first end being connected in fluid flow relationship to a said inlet aperture of said container, said conduit extending through said open end of said filter screen such that said second end of said conduit is spaced apart from said closed end of said filter screen; and
said outlet aperture so located that the fluid may exit said container through said outlet only after having first passed through said filter screen.

Abstract
A self-cleaning filter assembly for removing suspended matter from fluids, primarily utilized in irrigation or similar distribution systems, resulting in reduced maintenance of the filter assembly as well as the total system. The filter assembly comprises a container having at least one inlet aperture and at least one outlet aperture therethrough and a filter screen, comprising a hollow perforated body, inserted within the container. One end of a conduit is connected in fluid flow relationship to the inlet aperture of the container while the other end of the conduit terminates within the hollow body comprising the filter screen. The outlet aperture is so located that the fluid entering the container through the fluid inlet aperture and the conduit must pass through the filter screen before exiting the container through the outlet aperture.

14. A filter assembly for removing suspended matter from a fluid, said assembly comprising:
-
a container, said container having a base, a lid and at least one wall therebetween, said container having an interior surface and an exterior surface, and said container having an inlet aperture passing through said base, an outlet aperture passing through said wall proximal to said lid and a flushing aperture passing through said wall proximal to said base; a filter screen comprising a hollow perforated body having an open end with a peripheral edge, and a closed end, said open end having a larger perimeter than said closed end, and said filter screen being inserted within said container such that said open end of said filter screen is proximal to said base and said closed end of said filter screen is proximal to said lid; a flange attached to said interior surface of said wall intermediate said lid and said base of said container, said peripheral edge of said open end of said filter screen being connected to said flange so that said filter screen is retained in a predetermined spatial relationship with said container; a conduit having a first open end and a second open end, said first end of said conduit being connected in fluid flow relationship with said inlet aperture of said container, said conduit extending through said open end of said filter screen such that said second end of said conduit is located intermediate said open end of said filter screen and said closed end of said filter screen; a fluid distribution means connected in fluid flow relationship with said outlet aperture so that the fluid may exit said container through said outlet aperture and enter said distribution means, said outlet aperture so located that the fluid must pass through said filter screen before exiting said container; and a flushing means connected in fluid flow relationship with said flushing aperture such that the filtered matter filtered from the fluid by said filter screen may be removed from said container.
