Abstract
A media supply pot for holding an amount of a particulate abrasive includes a vertically disposed valve tube communicating with a source of compressed air and a slidable pop-up valve therein which seals off the media inlet of the supply pot when compressed air is passed through the valve tube. To prevent moisture from entering the supply pot, the valve tube includes an insert in the form of a downwardly sloping cone, the base of which contacts the sidewalls of the valve tube to prevent moisture from passing upwardly along the sidewall of the valve tube and into the supply pot, the insert including a centrally disposed narrow passage which allows the compressed air to flow through the valve tube and out into the supply pot. The narrow passage slows down the supply of compressed air to the pot, and prevents the rapid cooling of the expanding gas and consequent precipitation of entrapped moisture onto the media.
