PNEUMATICALLY OPERATED AVERAGING RELAY CONSTRUCTION AND SYSTEM UTILIZING THE SAME

摘要

A housing means carrying a plurality of diaphragm members disposed in stacked relation and cooperating with the housing means to define a plurality of chambers disposed in stacked relation and separated from each other by the diaphragm members. Each diaphragm member has a central post means and a plurality of integral diaphragm portions axially spaced on the post means and extending radially outwardly therefrom in substantially parallel spaced relation to each other. Interconnecting means interconnect the post means of the diaphragm members together whereby the diaphragm members are adapted to move in unison in the housing means.
