Abstract

Válvula de control (1) con una envuelta, que tiene una conexión (13) de la bomba, un dispositivo de conexión (9, 10) del depósito, un dispositivo de conexión de trabajo (5, 6) y un dispositivo de conexión de presión de carga, conectados cada uno con un dispositivo de apertura (14, 11, 12, 7, 8, 15, 16) en una superficie de control, y con una corredera (3) dispuesta móvil en la envuelta (2) y que coopera con la superficie de control, teniendo la corredera ranuras (17, 18) y/o canales (19, 22) de tal modo que conecta o separa dispositivos de apertura predeterminados unos con/de otros. Con el fin de mejorar la estanqueidad, está previsto un dispositivo de conexión auxiliar (31, 32) del depósito adicional, que está conectado con un dispositivo de apertura auxiliar (27, 28) del depósito en la superficie de control. La corredera (3) tiene un tubo o ranura auxiliar (29, 30) del depósito que, en su posición neutra, conecta el dispositivo de apertura auxiliar (27, 28) del depósito con el dispositivode apertura (15, 16) de presión de carga.
