Abstract:
1. A pressure regulator apparatus usable with an aerosol supply device containing a fluid, the pressure regulator apparatus comprising: an inflatable diaphragm unit including an upper surface member, a lower surface member, and a diaphragm chamber formed between the upper surface member and the lower surface member; an output port member having an output cavity and an output port, at least a portion of the output port member is disposed within and in fluid communication with the diaphragm chamber; a valve actuator including an actuator cavity and one or more actuator openings in fluid communication with the output port, at least a portion of the valve actuator is moveably disposed within the output cavity; an input port member having an input port configured to allow the fluid to enter the actuator cavity, at least a portion of the input port member is disposed proximate to the actuator cavity; and an axial flow path extending between the input port and the output port, and configured to allow the fluid to selectively pass in an axial direction therethrough; wherein the valve actuator moves to close and open the input port based on an inflation status of the inflatable diaphragm unit to regulate a pressure of the fluid to be transported from the inflatable diaphragm unit constant.
