ABSTRACT:
A substantially cylindrical, plug-type configuration of the element offers a mass which is less responsive to non-uniform and unsteady pressures, and channeling therein opens centrally, and about the periphery thereof, onto a recess formed in an end of the element which closes onto a valve seat. The channeling and recess are cooperative to assure that the balance-end of the element will have average, representative pressures conducted thereto.
