Abstract
A compressor apparatus having a first compressor head for generating a first gas flow and a second compressor head for generating a second gas flow with a shuttling by-pass component in fluid flow communication between the first and second compressor heads for allowing the output of a portion of either the first gas flow or the second gas flow to be diverted to the other compressor head. The shuttling by-pass component allows a portion of the first gas flow to be diverted from the first compressor head to the second compressor head during an exhaust stroke of the first compressor head, while also allowing a portion of the second gas flow to be diverted from the second compressor head to the first compressor head during an exhaust stroke of the second compressor head in alternating sequence such that a more steady output of gas flow may be attained.
