Abstract

Perfeccionamientos en dispositivos de seguridad contra la elevación de la presión en un circuito de control oleoneumático, que comprenden aguas arriba un generador de presión y aguas abajo un acumulador oleoneumático, caracterizados porque comprenden entre el generador y el acumulador una válvula principal anti-retorno, una primera válvula de seguridad capaz de un caudal al menos igual al del generador aguas arriba de la válvula principal, una segunda válvula de seguridad aguas abajo de la válvula principal y medios para que la segunda válvula de seguridad sea solo sometida a un reducido caudal. *** Ver imagen 01
