ABSTRACT:
A fill valve, or aspirator, which is adapted to be connected to a superatmospheric pressure source, such as helium, and which is capable of intermixing at least two fluids in intimate fashion, wherein in one embodiment, actuation of a slide-like member allows introduction of a second fluid, for example, ambient atmosphere, so that ambient atmosphere is drawn into the fill valve by reason of a venturi effect due to the interior configuration of the fill valve so that an air and helium mixture may be obtained. The fill valve ideally, in the most efficacious embodiment may be utilized for filling inflatable members with a combination of air and helium so as to decrease the cost of the fluid for inflating the inflatable article. However, in other embodiments the fill valve may be used for other desirable end functions wherein it is desired to intimately intermix at least two fluids wherein one of the fluids is at a higher pressure than the other and due to the venturi construction of the interior of the fill valve, introduction of the second fluid is readily obtained for intimate intermixing with the higher pressure gas or fluid.
