Beschreibung
Zusammenfassung:	An output pressure control apparatus particularly adapted for HVAC control applications, and being of the general type which admits a higher supply pressure to a controlled output line when it is desired to increase the pressure in the output line and which bleeds pressure from the controlled output line when it is desired to reduce the pneumatic output pressure. The pressure regulating apparatus requires only a single filter means and utilizes bidirectional flow of air through the filter means during normal operation which cleans the filter means.
