1. A device, comprising:
a housing, comprising:
a first chamber having a first pressure regulating device,
wherein the first chamber comprises a first fluid inlet and a first fluid outlet;
wherein the first pressure regulating device comprises:
a plurality of first levers;
a first spring having a first spring force;
 wherein the first spring force is configured to provide a first closing force for closing the first fluid inlet;
a first pressure activated device;
 wherein the first pressure activated device is configured to constrict as an external pressure increases;
wherein in response to the external pressure decreasing, the first pressure activated device is configured to overcome the first closing force and open the first fluid inlet; and
a second chamber having a second pressure regulating device;
wherein the second chamber comprises a second fluid inlet and a second fluid outlet;
wherein the second pressure regulating device comprises:
a plurality of second levers;
a second spring having a second spring force;
 wherein the second spring force is configured to provide a second closing force for closing the second fluid inlet;
a second pressure activated device;
wherein the second pressure activated device is configured to constrict as the external pressure increases;
wherein in response to the external pressure decreasing, the second pressure activated device is configured to overcome the second closing force and open the second fluid inlet.
