• a piston;
• said piston axially movable between extended and retracted piston positions within said interior chamber;
• a cylinder fluid gap formed between at least a portion of an inner surface of said outer tube and at least a portion of an outer surface of said cylinder sleeve;
• said cylinder fluid gap allows fluid flow through said cylinder fluid gap;
• a tube fluid gap formed between at least a portion of an outer surface of said outer tube and at least a portion of an inner surface of said manifold housing;
• said tube fluid gap allows fluid flow into and out of said tube fluid gap;
• and
• a bottom end gap formed between a bottom end of said outer tube and said manifold housing;
• said bottom fluid gap allows fluid flow between said cylinder fluid gap and said tube fluid gap.

A method for lubrication of a gas cylinder assembly comprising:

• providing a gas cylinder assembly;
• said gas cylinder assembly includes:
• an outer tube supported in a first cavity of a housing;
• said outer tube includes an inner chamber;
• a cylinder sleeve supported in a second cavity of said housing;
• said cylinder sleeve includes an interior chamber;
• at least a portion of a bottom portion of said cylinder sleeve is telescopically positioned at least a portion of said inner chamber of said outer tube;
• a piston;
• said piston axially movable between extended and retracted piston positions within said interior chamber;
• a non-solid lubricant;
• a cylinder fluid gap formed between at least a portion of an inner surface of said outer tube and at least a portion of an outer surface of said cylinder sleeve;
• said cylinder fluid gap allows fluid flow through said cylinder fluid gap as said piston axially moves between said extended and retracted piston positions;
• a tube fluid gap formed between at least a portion of an outer surface of said outer tube and at least a portion of an inner surface of the manifold housing;
• said tube fluid gap allows fluid flow into and out of said tube fluid gap as said piston axially moves between said extended and retracted piston positions;
• and
• a bottom end gap formed between at least a portion of a bottom end of said outer tube and said housing;
• said bottom fluid gap allows fluid flow between said cylinder fluid gap and said tube fluid gap as said piston axially moves between said extended and retracted piston positions;
• said bottom end gap includes said non-solid lubricant;
• moving said piston from said retracted piston position to said extended piston position to cause a fluid to flow from said tube fluid gap, into and through said bottom fluid gap, into and through said cylinder fluid gap, and then into said interior chamber of said cylinder sleeve;
• and
• wherein said fluid that passes into and through said bottom fluid gap at least partially interacts with said non-solid lubricant in said bottom fluid gap to thereby cause at least a portion of said non-solid lubricant to become atomized and mixed with said fluid;
• and
• wherein said atomized non-solid lubricant at least partially lubricates an inner surface of said interior chamber of said cylinder sleeve after said atomized non-solid lubricant enters into said interior chamber of said cylinder sleeve.
