Abstract
EN LAS VALVULAS YA CONOCIDAS DE INYECCION DE COMBUSTIBLE, LAS PARTES DE DESGASTE TALES COMO LA ARMADURA Y EL NUCLEO ESTAN PROVISTAS CON CAPAS RESISTENTES AL DESGASTE, ELABORADAS POR EJEMPLO A PARTIR DE CROMO, MOLIBDENO O NIQUEL. SI LAS PARTES DE LAS VALVULAS DE INYECCION ESTAN RECUBIERTAS DE FORMA GALVANICA, SE CONSIGUE UNA DISTRIBUCION PERFILADA DE CUÑA DESEADA DEL ESPESOR DE LA CAPA, QUE CREA SOLAMENTE UNA PEQUEÑA AREA DE SOPORTE PERO QUE ESTA PREDESTINADA FISICAMENTE Y DE FORMA PRACTICAMENTE IMPOSIBLE A SER INFLUENCIA. LA NUEVA VALVULA DISPONE AL MENOS DE UNA PARTE, POR EJEMPLO LA ARMADURA (27) QUE TIENE UNA SUPERFICIE ESCALONADA ANTES DE QUE SE APLIQUE LA CAPA RESISTENTE AL DESGASTE. LA SUPERFICIE ESCALONADA PUEDE SER ELABORADA EN UNA MANERA VARIABLE DEPENDIENDO DE LAS PROPIEDADES DESEADAS MAGNETICAS E HIDRAULICAS OPTIMAS. LA SECCION (69) SOPORTE EN PERFIL DE ANILLO FORMADA POR MEDIO DEL ESCALON DISPONE DE UNA SUPERFICIE DE SOPORTE DEFINIDA O UNA ANCHURA (B) DE CONTACTO QUE PERMANECE CONSTANTE DURANTE LA VIDA COMPLETA DE SERVICIO DEL COMPONENTE, COMO SUPERFICIE DE DESGASTE O DE SOPORTE EN LAS CONDICIONES DE SERVICIO CONTINUO, QUE NO ORIGINAN EL INCREMENTO DE LA ANCHURA DE CONTACTO. ESTA VALVULA ES PARTICULARMENTE ADECUADA PARA SU UTILIZACION EN SISTEMAS DE INYECCION DE COMBUSTIBLE O CON PRESION DE MEZCLAS, EN MOTORES DE COMBUSTION INTERNA CON ENCENDIDO POR BUJIA.IN ALREADY KNOWN FUEL INJECTION VALVES, WEAR PARTS SUCH AS ARMOR AND NUCLEUM ARE PROVIDED WITH WEAR RESISTANT LAYERS, MADE BY EXAMPLE FROM CHROME, MOLDED OR NICKEL. IF THE PARTS OF THE INJECTION VALVES ARE COVERED GALVANICALLY, A PROFILED DISTRIBUTION OF THE DESIRED WEDGE OF THE LAYER THICKNESS IS CREATED, WHICH ONLY CREATES A SMALL SUPPORT AREA, BUT IT IS FOREIGNLY FORWARD AND FORWARD. THE NEW VALVE HAS AT LEAST ONE PART, FOR EXAMPLE THE REINFORCEMENT (27) WHICH HAS A STEPPED SURFACE BEFORE WEAR RESISTANT COAT IS APPLIED. THE STEPPED SURFACE CAN BE ELABORATED IN A VARIABLE WAY DEPENDING ON THE DESIRED OPTIMAL MAGNETIC AND HYDRAULIC PROPERTIES. SECTION (69) RING PROFILE SUPPORT FORMED BY THE STAGE HAS A DEFINED SUPPORT SURFACE OR A CONTACT WIDTH (B) THAT REMAINS CONSTANT DURING THE COMPLETE SERVICE LIFE OF THE COMPONENT, AS WEAR AND SUPPORT SURFACE THE CONDITIONS OF CONTINUOUS SERVICE, WHICH DO NOT ORIGINATE THE INCREASE IN THE CONTACT WIDTH. THIS VALVE IS PARTICULARLY SUITABLE FOR USE IN FUEL INJECTION SYSTEMS OR WITH MIXTURE PRESSURE, IN INTERNAL COMBUSTION ENGINES WITH SPARK PLUG IGNITION.
