ABSTRACT:
The present invention provides an agent dispenser, a method and an apparatus for introducing an agent into a liquid or gas where the agent is miscible with such liquid or gas. The agent dispenser comprises a hollow casing constructed of a material having a coefficient of cubical expansion that differs from the coefficient of cubical expansion of the liquid or gas. At least one opening is provided in the hollow casing for permitting the flow of the liquid or gas to and from the interior of the hollow casing. The dispenser contains the agent and the agent is introduced into the liquid or gas through liquid or gas drawn into and expelled from said dispenser as a result of variations in the internal pressure of the dispenser resulting from thermal expansion and contraction of the dispenser and its contents caused by variations in the temperature of the liquid or gas surrounding the dispenser.
