Abstract

REFERIDO A UN MECANISMO INDICADOR PARA UNA VALVULA HIDRAULICA DE UN DISPOSITIVO INFLADO HIDRAULICAMENTE QUE INCLUYE UN CUERPO QUE TIENE UNA PERFORACION A TRAVES DE LA CUAL FLUYE UN FLUIDO DESDE UNA FUENTE HASTA UNA PARTE INTERIOR DEL DISPOSITIVO Y QUE ESTA CONFIGURADA PARA DEFORMARSE, CUANDO UNA PRESION DE FLUIDO DESDE LA FUENTE ALCANZA UN NIVEL PREDETERMINADOREFERRED TO AN INDICATOR MECHANISM FOR A HYDRAULIC VALVE OF A HYDRAULICALLY INFLATED DEVICE INCLUDING A BODY HAVING A PERFORATION THROUGH WHICH A FLUID FLOWS FROM A SOURCE TO AN INSIDE PART OF THE DEVICE CONFIGURED AND WHICH IS A DEVICE CONFIGURATION. FLUID FROM THE SOURCE REACHES A DEFAULT LEVEL
