A fuel vent connector includes a longitudinal axis and a flow path a long the longitudinal axis. The connector further includes a first portion pivotally supporting a plurality of fingers, each finger amongst the plurality of fingers having a latching head biased radially outwardly and configured to latch within a fuel vent opening. The connector further includes a second portion biased longitudinally away from the first portion with respect to the longitudinal axis. The flow path extends through the first and second portions, and longitudinal movement of the second portion towards the first portion moves the fingers radially inward.

A canister includes a main chamber where a charge port and a purge port are located, and at least one subsidiary chamber. Any one of the at least one subsidiary chamber includes an atmosphere port. The at least one subsidiary chamber includes at least one specified subsidiary chamber including a specified absorption layer containing specified activated carbon. An L/D of the specified absorption layer is equal to or greater than 2.0 and equal to or less than 7.0 where L is a length of the specified absorption layer and D is an equivalent diameter of a cross-section of the specified absorption layer taken orthogonally to longitudinal directions. The specified activated carbon has BWC equal to or greater than 8.0 g/dL and equal to or less than 10.5 g/dL.

A method for transferring volatile liquid from a refueling tank to the fuel tank of an internal combustion device including the steps of providing a volatile liquid refueling apparatus, having a probe including an outer collar and a receiver including a receiving collar, where the outer collar and the receiving collar are configured to join to create a vapor-tight enclosure, installing the receiver in the fuel tank of an internal combustion device, installing the probe in the refueling tank, inserting the probe into the receiver, engaging the receiving collar and the probe outer collar to create a vapor-tight enclosure, transferring volatile liquid from the refueling tank to the fuel tank, and disengaging the probe from the receiver, including sealing the refueling tank and the tank.

A channel forming member is attached to a filler neck on a nozzle insertion side where a fueling nozzle is to be inserted. The channel forming member includes a barrier section that forms an insertion flow path section for the fueling nozzle in the fuel flow path on the nozzle insertion side, while forming an annular channel surrounding the insertion flow path section so as to separate the channel from the insertion flow path section. The channel forming member further includes the following provided to the barrier section: an atmosphere communication hole for making the channel communicate with the atmosphere; a flow path communication hole for making the channel communicate with an insertion end flow path section downstream from the insertion flow path section; and a valve mechanism that prevents passage of the atmosphere through the channel in a fueling period. This contributes to reduction in introduction of the atmosphere into the fuel flow path through the channel in a fueling period.

A volatile liquid refueling apparatus, which includes a probe including an outer collar, and a receiver including a receiving collar, where the outer collar of the probe and the receiving collar of the receiver are configured to join to create a vapor-tight enclosure, and where the receiver further includes a dual locking mechanism whereby the apparatus can be locked in either an open position or a closed position.

A kit of parts is provided that can include a plurality of hose connection parts selectable from, first hose connection parts comprising one fluid inlet and one fluid outlet, second hose connection parts comprising two fluid inlets and one fluid outlet, and third hose connection parts comprising three fluid inlets and one fluid outlet. The kit of parts can be suitable for assembling a hose connection having at least a first and second fluid inlet and a fluid outlet, according to any one of three configurations. The invention also relates to a fuel dispensing unit for refueling vehicles and a method for assembly a hose connection.

An insert is disclosed for use with a closed loop dispensing system. The insert is press-fitted into the throat of a liquid container. The insert includes a normally closed chemical valve which is opened when pierced by a vertically movable lance to permit the liquid in the container to be dispensed to a mixing machine or the like. The insert also includes a plurality of radially spaced-apart bi-directional valves which automatically permit air to be vented into the container. The bi-directional valves also permit off-gassing of gas in the container.

An insert is disclosed for use with a closed loop dispensing system. The insert is press-fitted into the throat of a liquid container. The insert includes a normally closed chemical valve which is opened when subjected to a suction force to permit the liquid in the container to be dispensed to a mixing machine or the like. The insert also includes a plurality of radially spaced-apart bi-directional valves which automatically permit air to be vented into the container. The bi-directional valves also permit off-gassing of gas in the container.

A fueling apparatus 1 including: a fueling pipe 4 accommodated in a housing main body 2 having a fueling mechanism, one end of the fueling pipe 4 being connected to the fueling mechanism; an elbow 5 connected to another end of the fueling pipe 4; a fueling hose 10, one end of which being connected to a fueling nozzle 11 with vapor recovering function, and in which a vapor passage 10c and a fuel oil passage 10d are separately disposed from each other; and a separable joint 9 for communicating the fuel oil passage 10d of the fueling hose 10 and inside of the elbow 5 with each other, and for communicating the vapor passage 10c of the fueling hose 10 and a vapor pipe 4 connected to the vapor recovery mechanism with each other.

A fuel tank system, comprising: a fuel tank configured to store a liquid fuel and a pressurized gaseous fuel capable of partially dissolving in the liquid fuel; a refueling conduit coupled to the fuel tank via a tank access valve; a first high pressure refueling port coupled to the refueling conduit; a low pressure refueling port coupled to the refueling conduit via a check valve. In this way, pressurized gaseous fuel or a pre-pressurized mix of fuels may be added to the fuel tank without active control any time the fuel pressure in the fuel tank is below a maximum allowable pressure, and liquid fuel may be added to the fuel tank with active control whenever the fuel pressure and liquid fuel level in the fuel tank are below threshold levels.
