Abstract

Système de pompe à air comprenant une pompe à air additionnel (20) de dépollution d’un moteur thermique de véhicule automobile, disposant d’un corps présentant une forme globalement cylindrique contenant une turbine centrifuge tournant autour d’un axe (A), et comprenant un support de pompe (12) réalisé en tôle, comportant une face plate (30) de fixation sur le moteur thermique, présentant un bord plié formant une face perpendiculaire (32) contenant deux pattes allongées (36) sensiblement parallèles à l’axe de la turbine (A), encadrant le corps de pompe, chaque patte (36) disposant à son extrémité d’un perçage recevant une vis (28) de fixation de la pompe (20), présentant dans une partie centrale de sa longueur un rétrécissement de largeur donnant une flexibilité amortissant des fréquences vibratoires.
