Abstract
UNA BOQUILLA DE INYECCION DE COMBUSTIBLE DE ELEVACION EN DOS ETAPAS QUE INCLUYE UN SOPORTE DE LA BOQUILLA (10) EN EL QUE HAY DEFINIDA UNA CAMARA (16) QUE ALOJA UN PAR DE RESORTES (15, 24) DISPUESTOS SEGUN UNA RELACION AXIAL. LOS RESORTES PROPORCIONAN UNA FUERZA DE POLARIZACION DE DOS ETAPAS A UN MIEMBRO DE VALVULA (13) QUE SE ENCUENTRA DISPUESTO DE FORMA DESLIZANTE EN UN CUERPO DE LA BOQUILLA (11) QUE SE ENCUENTRA ASEGURADO A UN EXTREMO DEL SOPORTE. EL RESORTE (24) QUE SE ENCUENTRA DISPUESTO ADYACENTE AL CUERPO DE LA BOQUILLA SE ENGANCHA A UN MIEMBRO DE REACCION (26) A MODO DE COMPONENTE ANULAR (30) QUE DEFINE UNAS PATILLAS (31) QUE SE PUEDEN EXTENDER HACIA AFUERA HASTA QUEDAR ACOPLADAS A MODO DE SUJECION A LA PARED DE LA CAMARA MEDIANTE UNA CLAVIJA (32) QUE SE ENCUENTRA ACOPLADA DE MANERA ROSCADA AL COMPONENTE.A TWO STAGE ELEVATION FUEL INJECTION NOZZLE INCLUDING A NOZZLE SUPPORT (10) IN WHICH A CHAMBER (16) HAS BEEN DEFINED ACCOMMODATING A COUPLE OF SPRINGS (15, 24) ARRANGED ACCORDING TO AN AXIAL RELATION. THE SPRINGS PROVIDE A TWO STAGE POLARIZATION FORCE TO A VALVE MEMBER (13) WHICH IS SLIDINGLY ARRANGED IN A NOZZLE BODY (11) WHICH IS SECURED AT ONE END OF THE SUPPORT. THE SPRING (24) WHICH IS FOUND ADJACENT TO THE NOZZLE BODY IS HITCHED TO A REACTION MEMBER (26) AS A NON-COMPONENT (30) WHICH DEFINES A PINS (31) THAT CAN BE EXTENDED OUTWARD UNTIL THEY ARE COUPLED METHOD OF FASTENING TO THE WALL OF THE CHAMBER THROUGH A PIN (32) WHICH IS COUPLED THREADED TO THE COMPONENT.
