Pneumatisches Druckrelais

A supply biased pneumatic pressure relay is provided for a fluid actuator control valve assembly. A supply pressure inlet (126) communicates to an actuator pressure outlet (124) through a supply port (132). An input diaphragm (130) is coupled to a variable pressure control inlet (122), the diaphragm...

Zusammenfassung:	A supply biased pneumatic pressure relay is provided for a fluid actuator control valve assembly. A supply pressure inlet (126) communicates to an actuator pressure outlet (124) through a supply port (132). An input diaphragm (130) is coupled to a variable pressure control inlet (122), the diaphragm being coupled to a valve plug (138) engageably contacting the supply port (132). The pressure supply from the inlet (126) is also communicated through a capillary hole (164) to supply biased cavity means (162). A substantially constant supply of pressure is thereby maintained in operation of the relay.
