Abstract

MECANISMO INDICADOR PARA SER USADO CON UNA VÁLVULA HIDRÁULICA (14) DE UN DISPOSITIVO INFLADO HIDRÁULICAMENTE (12) PARA EL SOPORTE DE UNA EXCAVACIÓN, QUE ÍNDICA SI DICHO DISPOSITIVO INFLADO HIDRÁULICAMENTE (12) HA SIDO INFLADO SUFICIENTEMENTE SIN OBSTRUIR EL FLUJO DE FLUIDOS A TRAVÉS DE LA VÁLVULA (14), INCLUYENDO DICHO MECANISMO UN CUERPO (18) QUE TIENE UNA PERFORACIÓN (32) A TRAVÉS DE LA CUAL FLUYE UN FLUIDO DESDE UNA FUENTE HASTA UNA PARTE INTERIOR (34) DEL DISPOSITIVO INFLADO HIDRÁULICAMENTE (12), Y QUE ESTÁ CONFIGURADO ARA DEFORMARSE CUANDO UNA PRESIÓN DE FLUIDO DESDE LA FUENTE ALCANZA UN NIVEL PREDETERMINADO.INDICATOR MECHANISM TO BE USED WITH A HYDRAULIC VALVE (14) OF A HYDRAULICALLY INFLATED DEVICE (12) FOR THE SUPPORT OF AN EXCAVATION, WHICH INDICATES IF SUCH A HYDRAULICALLY INFLATED DEVICE (12) HAS BEEN INFLATED WITH ITS FLOWING, WITHOUT ITS FLOWING, WITHOUT ITS FLOWING. THE VALVE (14), INCLUDING SAID MECHANISM A BODY (18) HAVING A PERFORATION (32) THROUGH WHICH A FLUID FLOWS FROM A SOURCE TO AN INTERIOR PART (34) OF THE HYDRAULICALLY INFLATED DEVICE (12), AND WHICH IS SET TO DEFORM WHEN A FLUID PRESSURE FROM THE SOURCE REACHES A DEFAULT LEVEL.
