Abstract
A vent system for an enclosure containing a liquid, the system comprising a vent module including a housing defining a passageway, a membrane maintained in the passageway, and a sorbent maintained in the passageway; and a flow control module associated with the vent module and including a valve having an inner channel through which air is able to flow in a first direction and a second, opposite direction through the valve, where the flow control module acts as a barrier to liquid flow through the valve from the enclosure toward the sorbent.
Claims18
A vent system for an enclosure containing a liquid, the system comprising:
- a flow control module associated with the vent module and including a valve having an inner channel through which air is able to flow in a first direction and
- a second, opposite direction through the valve, where the flow control module acts as a barrier to liquid flow through the valve from the enclosure toward the sorbent.
A vented system comprising:
- an enclosure containing a liquid;
- a vent module including a housing defining a passageway in pneumatic communication with the enclosure, a membrane maintained in the passageway, and a sorbent maintained in the passageway;
- and
- a flow control module associated with the vent module and including a valve having an inner channel through which air is able to flow in a first direction from the enclosure through the vent module and a second, opposite direction while acting as a barrier to liquid flow through the valve from the enclosure.
A valve for a vent system, the valve comprising a body having a first end, a second end and an inner channel extending from the first end to the second end, the inner channel defining a tapered section that decreases in width in a direction from the first end toward the second end to a slot formed at the second end, the slot being adapted to allow air to flow in a first direction and a second, opposite direction through the inner channel and the tapered section of the inner channel being adapted to flex closed under pressure.
