Abstract:
The present disclosure is directed to devices for dispensing liquid, especially fuel. In one embodiment, a device for dispensing fuel includes a spout for pouring liquid fuel, an annular fitting including a chamber formed therein. A sealing surface, a stopper, and spring may be disposed within the chamber. The annular fitting may be attached to the spout. The annular fitting may be configured to mate with a portable fuel canister. The fitting may include sidewalls forming a channel for liquid fuel, an outer wall enveloping a portion of the sidewall forming a chamber proximate the liquid channel, and an atmospheric orifice formed in the outer wall. The sealing surface may be disposed proximal the orifice. The spring may be configured to bias the stopper into contact with the sealing surface such that the chamber is in selective pressure-dependent fluid communication with an atmosphere outside the device.

Claim (Index 1):
A device for dispensing fuel, comprising:\n a spout for pouring liquid fuel; an annular fitting attached to the spout configured to mate with a portable fuel canister, the fitting having;\n sidewalls forming a channel for liquid fuel; \n an outer wall enveloping a portion of the sidewall forming a chamber proximate the liquid channel; \n an atmospheric orifice formed in the outer wall; and \n wherein the annular fitting comprises an annular cap encircling the sidewalls of the spout and covering one end of the chamber, the atmospheric orifice being formed in the cap: \n a sealing surface disposed within the chamber, proximal the atmospheric orifice; a stopper disposed within the chamber; and a spring configured to bias the stopper into contact with the sealing surface such that the chamber is in selective pressure-dependent fluid communication with an atmosphere outside the device.
