Abstract

L'invention concerne un appareil comportant un moteur hydraulique pouvant être commandé au moyen d'une soupape. Dans cet appareil, des soupapes de retenue 26, 27 reunies dans un boîtier 8 sont disposées dans des conduites d'arrivée et de retour 4, 5 et comportent pour leur ouverture, des organes d'actionnement 38, 38' entre lesquels est disposé, dans une chambre cylindrique 39, un piston de commutation 40 déplaçable longitudinalement et dont les faces frontales sont chargées par le fluide d'arrivée et de départ et qui agit sur lesdits organes d'actionnement. Application notamment aux appareils de commande de tables formant couchettes pour patients, à commande hydraulique.
