Abstract

Pompe à membrane à dépression pour actionner des organes de véhicules automobiles, la membrane de cette pompe étant entraînée par un arbre à manivelle et par l'intermédiaire d'une biellette. Selon l'invention, l'enceinte de la pompe située du côté de la membrane 1 tourné vers la biellette 4 est reliée à l'atmosphère par l'intermédiaire d'au moins une valve de retenue 3 qui permet l'entrée d'air dans ladite enceinte 2 mais en interdit toute sortie. Application à la commande des amplificateurs de puissance de freinage de véhicules automobiles.Vacuum diaphragm pump for actuating parts of motor vehicles, the diaphragm of this pump being driven by a crank shaft and via a connecting rod. According to the invention, the chamber of the pump located on the side of the membrane 1 facing the rod 4 is connected to the atmosphere by means of at least one check valve 3 which allows the entry of air. in said enclosure 2 but prohibits any exit. Application to the control of motor vehicle braking power amplifiers.
