Title: RETROFITTABLE NO FILTER NO RUN FILTRATION SYSTEM
Abstract:
A no filter no filter no run attachment is disclosed. A shell defines a fluid passage from an upstream fluid aperture at a first end for fluid receiving communication with a filtration cartridge to a downstream fluid aperture at a corresponding second end sized and shaped for coupling to a fluid pump inlet. The shell further defines a pin aperture at the first end sized to receive a pin from the filtration cartridge. A divider segments the fluid passage into an upstream portion that comprises the upstream fluid aperture and the pin aperture and a downstream portion that comprises the downstream fluid aperture. The divider also defines an internal aperture that allows fluid communication between the upstream portion and the downstream portion. A ball is disposed in the upstream portion in fluid flow receiving communication with the upstream fluid aperture, and is sized to have a greater diameter than the internal aperture.
