Abstract
A closed system odorant chamber or wick-style odorizer and method for transferring odorant to an odorant chamber is described. Two cylinders are connected to the odorant chamber, which in turn may be connected to a gas line. The pressure differential between the two cylinders causes odorant to flow into the odorant chamber until an appropriate odorant level is reached. After filling up the odorant chamber, the two cylinders are disconnected from the odorant chamber. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure; and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims under 37 C.F.R. § 1.72.
