Abstract

Una bomba de vacío de pistón en especial una bomba de depresión expuesta a elevadas fluctaciones de temperatura en vehículos caracterizada poruqe el diámetro del pistón está escalonado en una superficie frontal porque en la zona de ranura más profunda y más próxima a la superficie frontal está insertado un anillo tórico elástico cuyo diámetro exterior es mayor que el diámetro de la zona más plana de la ranura está colocado un anillo de material sintético de sección rectangular que está asegurado contra desplazamiento axial por un disco que corresponde al diámetro del pistón.
