Abstract

A pivotal armature on which a resilient elastomeric body is mounted, is arranged to be engageable with first and second surfaces in a manner which limits its movement and which holds the armature in a first closed valve position wherein the elastomeric body is permitted to engage and close a valve port but prevented from undergoing excessive deformation and a second valve open position wherein the elastomeric body is moved just sufficiently to open the port.
