A pneumohydropumping installation comprises a two-way pneumohydraulic booster (2) the pneumatic chambers of which are connected with the outlets of a power pneumatic distributor. The hydraulic chambers of the booster (2) are connected with an actuating hydraulic engine (1) through a force and a drain line (14, 15). The booster (2) is provided with pneumatic limit switches (26, 27). The installation further comprises a one-way pneumohydraulic booster (30) provided with a pneumatic limit switch (33). The pneumatic chambers (30a, 30b) of the booster (30) are connected with the outlets of a four-line two-position pneumatic distributor (34). L'INVENTION CONCERNE LES MOYENS DE COMMANDE PNEUMOHYDRAULIQUES.L'INSTALLATION FAISANT L'OBJET DE L'INVENTION EST CARACTERISEE NOTAMMENT EN CE QU'ELLE COMPORTE UN ACCUMULATEUR PNEUMOHYDRAULIQUE 22 BRANCHE SUR LA CONDUITE DE REFOULEMENT 14 A TRAVERS UNE SOUPAPE DE RETENUE HYDRAULIQUE 23 ET UNE SOUPAPE DE REDUCTION HYDRAULIQUE 24, LE MULTIPLICATEUR PNEUMOHYDRAULIQUE A DOUBLE EFFET 2 POSSEDANT DES INTERRUPTEURS PNEUMATIQUES DE FIN DE COURSE 26, 27 DONT LES SORTIES 26A, 27A SONT RACCORDEES AUX ENCEINTES DE COMMANDE 8, 9 DU DISTRIBUTEUR DE PUISSANCE PNEUMATIQUE 7 ET AUX ENTREES D'UNE SOUPAPE DE SEPARATION PNEUMATIQUE "OU" 25 DONT LA SORTIE EST RELIEE A L'ENCEINTE DE COMMANDE 23B DE LA SOUPAPE DE RETENUE HYDRAULIQUE 23 DE L'ACCUMULATEUR PNEUMOHYDRAULIQUE 22.L'INVENTION PEUT ETRE UTILISEE EN PARTICULIER DANS LES COMMANDES DES ROBOTS INDUSTRIELS.
