Abstract
Perfeccionamientos en motores hidráulicos de movimiento alternativo, caracterizado porque se dota a cada motor de un pistón y un cilindro que tiene una cara de pistón expuesta a la presión en una cámara de comprensión que se conecta de lumbreras controladas por el pistón a una fuente de presión de suministro en una parte extrema de su carrera, mientras que entre estas partes de los extremos de las carreras existe un recorrido de comprensión/expansión durante el cual la cámara de comprensión de cierra y el líquido en su interior se expande alternativamente sobre una gama de presión más elevada y se comprime sobre una gama de presión inferior.
