Abstract

L'invention concerne un dispositif de réduction des chocs de sélection et de passage de vitesses dans une transmission automatique de véhicule. Ce dispositif comprend un accumulateur 1 contenant un piston étagé 5 et associé à une soupape 2 de réduction de pression, de façon à limiter la pression amenée à une unité à friction quand une pression est fournie à une autre unité à friction de la transmission automatique. L'invention concerne en particulier les transmissions automatiques de véhicule automobile.
