Abstract
A method for maintaining the pressure of a compressible fuel resident in a reservoir above a predetermined minimum including withdrawing compressed air from an internal combustion engine's combustion chamber, further compressing that withdrawn air, transmitting that further compressed air to an expandable air compartment which, with a fuel compartment having an outlet, occupies the interior of a reservoir. Apparatus for maintaining the pressure of a compressible fuel above a predetermined minimum including a reservoir having an air compartment and a fuel compartment separated by a moveable barrier, an internal combustion engine having a combustion chamber, means for transmitting air from the combustion chamber to the air compartment, a compressor for compressing the transmitted air, and a valve for obstructing air transmission when the fuel compartment's pressure exceeds a predetermined maximum.
