Abstract

LA PRESENTE INVENCION SE REFIERE A UNA VALVULA QUE RECIBE UN FLUIDO A PRESION EN UNA ENTRADA (5A) Y DESTINADA A LIBERAR, EN UNA SALIDA (6A) EL FLUIDO BAJO UNA PRESION DIFERENTE RESPECTO DE LA PRESION DE ENTRADA, COMPRENDIENDO ESTA VALVULA, EN UN CUERPO (1), UN PISTON (2), UNA CHAPALETA (3) Y UN EMPUJADOR (4). EL EMPUJADOR (4) ESTA MONTADO DE FORMA RETRACTIL EN EL CUERPO Y ABRE LA CHAPALETA (3) EN LA POSICION DE REPOSO DE LA VALVULA, PARA ASI ELIMINAR CUALQUIER DIFERENCIA ENTRE LAS PRESIONES DE ENTRADA Y DE SALIDA ANTE LA CERCANIA DE BAJAS PRESIONES.
