Abstract

Engranaje inversor que se puede cambiar bajo carga con un depósito de aceite (5) con embragues (1, 2) que se utilizan como engranajes inversores, que se pueden accionar mediante dispositivos de activación (8) y que se pueden cerrar o abrir a elección para el cambio del sentido, cerrándose los embragues (1, 2) mediante el descenso de una presión en la cámara de pistones (10, 23) que actúa contra una fuerza elástica de un resorte (12, 26) a través de perforaciones de entrada (9, 24) de los embragues (1, 2) y abriéndose mediante la elevación de una presión en la cámara de pistones (10, 23), caracterizado porque al menos una cámara de pistones (10, 23) presenta, como mínimo, dos perforaciones de entrada (9, 13, 22, 24), cerrándose siempre una primera perforación de entrada (13, 22) por medio de una válvula (14, 21) cuando una segunda perforación de entrada (9, 24) se somete a presión y fluyendo siempre por la cámara de pistones (10, 23) un caudal de líquido a través de una perforación de entrada (13, 22) cuando una segunda perforación de entrada (9, 24) se une al depósito de aceite (5) por medio de un dispositivo de activación (8).
