Zusammenfassung:	Systems, methods, and apparatus for regulating pressure within a well tool. In some aspects, the well tool may include a cylinder, a setting chamber, and a first flow metering device and a second flow metering device installed in the cylinder. The first flow metering device having a first pressure threshold and the second flow metering device having a second pressure threshold may be configured to regulate an internal chamber pressure inside the setting chamber to reduce a collapse pressure or a pressure differential at the cylinder. The first flow metering device may be configured to allow an external pressure greater than a first pressure threshold to enter the setting chamber during a hydrocarbon recovery operation, and the second flow metering device may be configured to allow the internal chamber pressure greater than a second pressure threshold to exit the setting chamber after the hydrocarbon recovery operation.
