Abstract

Cette pompe est du type possédant au moins une palette qui sépare un côté admission d'un côté sortie et est susceptible d'etre rétractée pour couper l'effet de pompage pendant que la pompe continue à être entraînée. Selon l'invention, le dispositif 19 à 25, pour la rétraction radiale des palettes 16 possède un cran d'arrêt 17' qui retient chaque palette mécaniquement à sa position de suppression de l'effet de pompage. Une telle pompe peut notamment servir de pompe à vide pour l'alimentation d'un frein à dépression sur un véhicule automobile.
