Abstract
A filler tube or hose and filter unit for disengageable attachment to and disposition within a filler pipe and within a communicating storage tank, and having as one component a flexible and reinforced hose, as a second component mounting or disengageable attaching means at the upper end of the hose for cooperation with the filler pipe mouth and for receipt of a closure cap, and as a third component filtering means at the lower end of the hose whereby said hose serves as the conduit for a smooth flow of fuel from the source or pump to the storage tank, and the filtering means serves both to eliminate impurities in the fuel and to aid in preventing sudden backsurge of the fuel from the tank in the event of accidental impact.
Claims6
A filler tube and filter unit for attachment to a filler pipe and liquid-fuel storage tank in communication therewith and adapted for vehicular engine and other equipment use, comprising as one component an imperforate flexible hose of a shatter-proof material of construction adapted to be insertable within and concentrically disposed along said filler pipe and terminating within said liquid-fuel storage tank, said flexible hose along the length thereof having continuous and smooth-surfaced inner walls and said filler pipe serving as a protective housing for said flexible hose, a second component comprising attaching means with a closure cap therefor and secured to and communicating with the upper end of the said hose for engagement with the mouth of the filler pipe whereby said hose serves as the sole conduit for flow of fuel from the source or pump to the fuel tank, and filtering means as a third component for the fuel and being secured to and communicating with the lower end of the said hose;
- said filtering means being of a predetermined permeability sufficient to prevent sudden back-surge of fuel from said fuel tank.
A filler tube and filter unit for attachment to the mouth of a filler pipe and concentrically disposed therein and extending into the liquid-fuel storage tank in communication with said filler pipe and adapted for vehicular engine and other equipment use, comprising as one component an imperforate flexible hose of a shatterproof material of construction having means at the upper end for detachable engagement with the mouth of the filler pipe and further means for detachable engagement with a closure cap, said flexible hose along the length thereof having continuous and smooth-surfaced inner walls and said filler pipe serving as a protective shell for said flexible hose, a filter assembly as the second component comprising a housing disengagably secured to the lower end of the said hose and in communication therewith, said housing having mounted within and thereacross a filter element of predetermined permeability sufficient to prevent sudden back-surge of liquid-fuel from said storge tank.
