Abstract
A low pressure pneumatic pressure regulator having particular application to the control circuits of system powered air distribution systems. A diaphragm separates a control chamber located above the diaphragm from an underlying output. The chambers communicate through a fixed orifice. A vent line extending from the control chamber includes an adjustable orifice which may be thermostatically controlled. An output line extending from the output chamber leads to the load controlled by the regulator. Power to operate the regulator can be supplied from the load or from a separate pressure source which connects with the output chamber through a supply port. An exhaust port which bleeds pressure from the output chamber when open is closed by the diaphragm unless the pressure differential between the chambers overcomes the diaphragm weight and possibly the added force applied by an optional spring. The pressure regulator can be used to control a number of terminal units from a common thermostat or as a pressure source for a number of terminal units each controlled by its own individual thermostat.
