Abstract

Dispositivo de mando para un motor hidráulico, con una válvula de cuatro vías para fijar la dirección de movimiento del motor, con una válvula de freno que está dispuesta en la tubería de retorno entre el motor y la válvula de cuatro vías y que está cargada en la dirección de cierre por un muelle y en la dirección de apertura por la presión de admisión del motor que actúa en una primera cámara de presión, y con medios para utilizar la tubería de retorno como tubería de admisión al producirse una inversión de la dirección de movimiento, caracterizado porque la válvula de cuatro vías presenta tanto en la dirección de retorno una estrangulación para ajustar la velocidad del motor, y porque la válvula de freno está cargada adicionalmente en la dirección de cierre por la presión que reina en una segunda cámara de presión delante de la estrangulación de retorno.
