Abstract
Apparatus and methods for filling a pressure compensated fluid container with a liquid. An example method includes restraining movement of a piston slidably disposed within the fluid container in a first piston position, wherein the piston divides the fluid container into first and second portions. The method further includes pumping the liquid into the first portion to compress gas located within the first portion, stopping the pumping of the liquid into the first portion, and stopping the restraining of movement of the piston to permit the piston to move to a second piston position due to expansion of the gas compressed within the first portion.
