Abstract

LA INVENCION SE REFIERE A UNA VALVULA PIEZOELECTRICA PARA CONTROLAR EL FLUJO DE UN FLUIDO, Y MAS PARTICULARMENTE A UNA VALVULA QUE NO ES SOLENOIDE NI SERVOASISTIDA. EN LA INVENCION CUANDO SE HACE REFERENCIA A FLUIDOS SE INCLUYEN TANTO LIQUIDOS COMO GASES. UNA FORMA PARTICULAR DE UNA VALVULA PIEZOELECTRICA PARA CONTROLAR EL FLUJO DE FLUIDOS COMPRENDE UN ALOJAMIENTO, UNA CAVIDAD DENTRO DEL ALOJAMIENTO, UN ELEMENTO EN FORMA DE DISCO DE UNA VALVULA PIEZOELECTRICA Y UN ASIENTO DE VALVULA, UN CONDUCTO DE ENTRADA Y UN CONDUCTO DE SALIDA PARA DIRIGIR EL FLUIDO AL INTERIOR Y AL EXTERIOR DE LA CAVIDAD Y QUE SE ENCUENTRAN DISPUESTOS EN LOS LADOS OPUESTOS DEL ELEMENTO DE LA VALVULA EN FORMA DE DISCO Y MEDIOS PARA SUJETAR EL ELEMENTO DE LA VALVULA EN FORMA DE DISCO EN UNA ZONA CENTRAL DEL ELEMENTO CON LA ZONA PERIFERICA DEL DISCO DISPUESTA PARA SU COOPERACION CON EL ASIENTO DE LA VALVULA DE FORMA QUE DESPUES DEL ACCIONAMIENTO DEL ELEMENTO MEDIANTE LA TENSION ELECTRICA APLICADA AL MISMO, LA PERIFERIA DELDISCO SE DESPLAZA Y AL MENOS UNA PARTE DE LA ZONA PERIFERICA DEL DISCO SIRVE PARA CONTROLAR EL FLUJO DEL FLUIDO ENTRE LOS CONDUCTOS DE ENTRADA Y DE SALIDA.
