Abstract
The present disclosure provides a unique pump for odorizing natural gas. The pump uses a bellows and a vanishing chamber technology (in combination with one another) to provide extremely precise and accurate, dependable and repeatable pumping technology. It does so while limiting the escape of odorant vapors to the atmosphere by keeping the bellows and the chamber physically separated from one another to reduce the need to access the chamber when performing maintenance on the pump.

A pump for introducing odorant into a pipeline, the pump including:
- a bellows;
- and
- a cup chamber in mechanical communication with the bellows;
- and
- a cup member received in the cup chamber, the cup member including a concave portion in which odorant may be contained;
- and
- wherein when the bellows acts on the cup chamber, the cup member acts on the concave portion to reduce concavity of the concave portion and eject odorant from the cup chamber and out of the pump.
