Abstract
The invention relates to a fluid compression apparatus comprising a sealed enclosure intended to contain a bath of cryogenic fluid, a first and a second compression chambers, an intake system for admission into the first chamber, a system for transfer from the first to the second chamber, the apparatus further comprising a communicating discharge orifice for compressed fluid to leave the second chamber, the apparatus further comprising an overflow discharge orifice provided with a valve for discharge from the first compression chamber to the bath so as to let surplus liquid leave during compression of fluid in the first chamber, the overflow discharge orifice communicating with the enclosure via at least one flow retarder configured to attenuate the speed and/or intensity of the discharged liquid flow by limiting its pressure drop.
