Title: Motor gravitatorio por presión de líquido
Inventor: TUSET CLADELLAS JORDI
IPC: F03G3/00
Filed: 2015-07-07
Granted: 2017-10-19
Abstract: Motor gravitatorio por presión de líquido. Constituido por un depósito sumergido en líquido y lleno de aire, dentro de dicho depósito hay instalada una transmisión vertical portadora de recipientes, guiada entre dos ejes principales. En la transmisión hay instalados unos recipientes que se llenan de líquido del exterior en la parte alta de la transmisión, y lo vacían en la parte inferior. Mediante un sistema de bombeo de líquido a presión, el líquido desechado es expulsado al exterior del depósito principal. Los recipientes descienden dando un sentido de giro a los ejes y a la transmisión que los sujeta. Este giro será acelerado mediante un multiplicador de velocidad con el fin de alimentar un sistema de bombeo de presión de líquido y un generador eléctrico de cualquier tipo convencional.
