Abstract

L'invention concerne des pompes à vide. Elle se caractérise en ce qu'un piston 3 entraîné dans un mouvement de va-et-vient est lié à ses extrémités à des membranes 8 qui déterminent des chambres munies de valves opposées 11, 12 disposées dans des conduits dont deux sont reliés ensemble et les deux autres servent respectivement à l'aspiration et à l'échappement. Application : servo-freins.The invention relates to vacuum pumps. It is characterized in that a piston 3 driven in a reciprocating motion is linked at its ends to membranes 8 which determine chambers provided with opposite valves 11, 12 arranged in conduits, two of which are connected together and the other two are used respectively for suction and exhaust. Application: servo-brakes.
