Title:
FILL LIMIT VENT VALVE HAVING VAPOR PERMEABLE MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2015/095500
Kind Code:
A3
Abstract:
A fill limit vent valve configured for use with a reductant tank includes a valve body, a float and a vapor permeable membrane. The valve body can define an inner chamber and has a valve outlet. The float has a float body configured to be received within the inner chamber and configured to sealingly engage the valve body. The vapor permeable membrane can be configured to permit vapor to pass through while inhibiting liquid from passing through. The float is movable between (i) an open position wherein vapor flows along a first flow path through the valve inner chamber and out of the valve body; and (ii) a closed position wherein the float sealingly engages the valve body and precludes vapor from flowing along the first flow path while allowing flow along a second flow path through the vapor permeable membrane and out of the valve body.
