Abstract

L'invention concerne une pompe rotative comprenant un bloc-cylindres cylindrique, un rotor à cames logé dans ledit bloc-cylindres et une plaque de séparation. La partie saillante du rotor, qui présente le diamètre le plus important, est en contact étanche avec la paroi interne du bloc-cylindres. La plaque de séparation pivote sur un arbre de support s'étendant axialement situé dans le bloc-cylindres. Les extrémités interne et externe opposées de la plaque de séparation sont respectivement en contact étanche avec la paroi interne du bloc-cylindres et la paroi externe du rotor. Un orifice d'admission et un orifice de sortie sont placés respectivement sur les côtés opposés de la plaque de séparation. Le bloc-cylindres est divisé en une chambre d'admission et une chambre d'échappement par la plaque de séparation et la saillie présentant le diamètre le plus important du rotor à cames.
