Abstract
A valve comprising a resiliently expansible and compressible plug movable in a valve chamber to open and close a flow passage intersected by the chamber. The plug has a sealing portion which is expanded outwardly against the walls of the chamber, e.g., by being compressed in a different direction to maintain a fluid type seal when the plug is moved in a chamber between open and closed positions of the valve.
