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.

A valve comprising: a first body in which a port is formed; an electromagnetic device mounted on said body; an armature, said armature being arranged to be movable toward and away from said port, said armature being proximate said electromagnetic device and arranged to move in a first direction when said electromagnetic device is energized; a spring, said spring being connected with said armature in a manner to bias said armature in a second direction opposite said first direction; a second body connected to said armature, said second body being arranged to engage said port in a manner to close the same when said armature is moved in one of said first and second directions; and a stopper arrangement arranged to limit the movement of said armature in said first and second directions, said stopper arrangement comprises an aperture formed in a member extending from said first body, said aperture having first and second opposed edges, said armature being received in said aperture in a manner that when said electromagnetic device is energized and moves in said first direction said armature moves toward and engages said first edge, and when said electromagnetic device is de-energized said spring moves said armature in said second direction toward and into engagement with said second edge.
