ABSTRACT:
A connector mechanism is provided to connect a spool in an air actuated valve to the diaphragm of an air actuating mechanism in order to permit rotational movement of the spool relative to the diaphragm. The connector mechanism includes a connector member having one end thereof firmly connected to the diaphragm and the other end thereof connected to one end of the spool and retained thereto by a retainer member which permits free rotation of the spool relative to the diaphragm during use of the air actuated valve.
