Abstract
The invention relates to a fluid compression apparatus comprising a first and a second compression chamber, an intake system communicating with the first compression chamber, a transfer system communicating with the first and second compression chambers, and a mobile piston for ensuring the compression of the fluid in the first and second compression chambers. The apparatus further comprises a discharge port which communicates with the second compression chamber and is configured to allow the outlet of compressed fluid, wherein the second compression chamber is defined by a part of the body of the piston and a fixed wall of the apparatus, the piston being translationally mobile according to a longitudinal direction, the piston having a tubular portion mounted around a fixed central guide, a terminal end of the central guide forming the fixed wall defining a part of the second compression chamber. The apparatus further comprises a sealing system formed between the central guide and the piston according to the longitudinal direction of translation of the piston, the intake system being located at a first end of the apparatus, the discharge port being located at a second end of the apparatus and the transfer system being located between the intake system and the discharge port.
