ABSTRACT:
A construction for an air dome is provided wherein the entrance area is substantially blocked off except for peripheral ports. It has been found that in fuel pumps, particularly where the fuel inlet port is below the air dome, that the flow of fuel into the dome can sometimes be at such a velocity that it washes out much of the air trapped within the dome and therefore defeats the air dome purpose. It has been found that the provision of a solid disk at the entrance to the air dome prevents such air washout, fuel entry being considerably restricted and confined to points at the disk edge. In particular, the use of such a disk in conjunction with an air dome of the type having longitudinal ridges, i.e., side flutes which normally are provided for the purpose of effecting fuel passage around the outside of the air dome, is used advantageously. Thus, fuel entry into the air dome to compress air therein is not washed out and the air dome remains effective. The invention effect is primarily for pumps where the inlet flow is directly towards the air dome.
