Title (EN) IMPROVED COMPRESSOR ARRANGEMENT AND METHOD OF WORKING THE SAME
(FR) AGENCEMENT DE COMPRESSEUR AMELIORE ET SON PROCEDE DE FONCTIONNEMENT
Abstract:
(EN) A method of operating a compressor arrangement having at least two pumping chambers of variable volume, each of which receives fluid to be compressed from a primary inlet when the respective pumping chamber has a first volume at least close to its maximum volume and each of which discharges compressed fluid from an outlet when the respective pumping chamber has a second volume which is less than said first volume, one of said pumping chambers having a secondary inlet open to the said one chamber when it has a third volume intermediate the first and second volumes after said one chamber is closed off from its primary inlet but before the said one chamber opens to its outlet is characterised in that the outlet of the other pumping chamber is fed to the secondary inlet of said one pumping chamber.
(FR) Procédé de fonctionnement d'un agencement de compresseur possédant au moins deux chambres de pompage de volume variable, chacune d'elle recevant d'une admission principale un fluide à comprimer lorsque la chambre de pompage respective renferme un premier volume au moins proche de son volume maximum, et chacune d'elles évacuant le fluide comprimé par un orifice d'évacuation lorsque la chambre de pompage respective renferme un deuxième volume inférieur au premier. L'une des chambres de pompage comporte une admission secondaire introduisant le fluide dans ladite chambre lorsque celle-ci renferme un troisième volume compris entre les premier et deuxième volumes, après fermeture de l'admission principale de cette chambre et avant ouverture de son orifice d'évacuation. Ce compresseur se caractérise en ce que l'orifice d'évacuation de l'autre chambre de pompage est raccordé à l'admission principale de la première chambre de pompage.
