发明名称 Fluid filler tool for a spin-on fluid filter
摘要 A fluid filler tool for a spin-on fluid filter comprises a tubular housing having an annular peripheral wall, an open end and a closed end. The closed end has one or more openings to allow fluid to flow therethrough and into fluid inlet ports of the fluid filter. The closed end has centrally located venting means for allowing air inside the filter to escape therefrom when the fluid filler tool is positioned on the filter and when the filter is being filled with fluid. The closed end has centrally located tool positioning means for allowing the filler tool to sealingly and removably fit into a centrally located fluid exit port of the spin-on filter. The fluid filler tool allows the filter assembly to be pre-filled with a fluid only through the fluid inlet ports and prevents any fluid from entering the fluid exit port of the filter assembly.
