US 12,743,114 B2 · Smart pressure regulator for aircraft oxygen system

Abstract

A pressure regulator system is disclosed. The system includes: a valve module; a controller; and a plurality of sensors. The controller is operably coupled to the valve module to adjust outflow of gas from an outlet of the valve module to a plurality of masks in an interior of an aircraft. The plurality of sensors comprises at least one of a pressure sensor and a temperature sensor and the controller is configured to receive feedback of sensed data at the outlet of the valve module about at least outlet pressure and ambient temperature from at least the pressure sensor and the temperature sensor and adjust the outflow of gas from the outlet of the valve module by determining an open-valve time based on the feedback of sensed data received from each sensor.

Dependent claims

A system for delivering gas to a plurality of masks in an interior of an aircraft, comprising:

a valve module;
a controller;
and
a plurality of sensors including a pressure sensor and a temperature sensor;
wherein the controller is operably coupled to the valve module to adjust outflow of gas from an outlet of the valve module to the plurality of masks;
wherein the controller is configured to:
receive feedback of sensed data at the outlet of the valve module about an outlet pressure and an ambient temperature from the pressure sensor and the temperature sensor,
select a preset stroke vs time profile based on the ambient temperature,
adjust the outflow of gas from the outlet of the valve module by determining an open-valve time based on the feedback of sensed data received from each sensor;
and
adjust a flow rate and a duration of time of the outflow of gas by commanding the valve module to transition from a closed position to an open position based on the preset stroke vs time profile to achieve a desired output pressure.
