Abstract
Wick material is included along the length of the interior and exterior walls of vapor recovery and product hoses, respectively, the product hose being carried within the length of the vapor recovery hose, whereby the wick material absorbs liquid entrapped between the hoses, and substantially increases the surface area of evaporation for the liquid, thereby substantially preventing liquid from blocking a portion of the vapor recovery path between the hoses.
Claims20
In a vapor recovery hose, apparatus for substantially preventing blockage of the vapor recovery path by liquid entrapped within the interior of said hose, comprising:
- wicking means within the interior of said vapor recovery hose for both absorbing said liquid, and substantially increasing the surface area of evaporation for said liquid.
In a gasoline dispensing system, the combination comprising:
- a vapor recovery hose;
- a product hose enclose within the length of the interior of said vapor recovery hose;
- and
- wicking means within the space between the inside and outside walls of said vapor recovery and product hoses, respectively, for both absorbing liquid entrapped in said space, and substantially increasing the surface area of evaporation for the liquid, thereby substantially preventing blockage of a vapor recovery path formed by said space.
