Abstract

Bu buluş, günümüzdeki modern içten yanmalı motorların yakıt püskürtme (enjeksiyon) sistemlerinde yaygın olarak kullanılmakta olan ve önemli bir role sahip enjektör elemanının, spickel bölümü olmaksızın manyetik sübap (3), birincil yay (1) ve ikincil yay (2) sistemi kullanılması ile ortaya çıkan yeni yapısını ve bu yapının mevcut uygulamalara karşı sahip olduğu avantajları içermektedir. Kullanılan yapısal gelişimler sayesinde sızdırma problemi bertaraf edilmiş, aktarma kanalının (4) enjektörün tam ortasından geçmesi suretiyle enjektörün et kalınlığı ile ilgili yaşanan problemler ortadan kaldırılmış, böylece dayanıma bağlı basınç eşik değerinin yükseltilmesi sağlanmıştır.This invention has emerged with the use of magnetic valve (3), primary spring (1) and secondary spring (2) system without the spickel part of the injector element, which is widely used in the fuel injection (injection) systems of today's modern internal combustion engines and has an important role. It includes the new structure that has emerged and the advantages of this structure against existing applications. Thanks to the structural developments used, the leaking problem has been eliminated, and the problems related to the wall thickness of the injector have been eliminated by passing the transfer channel (4) right in the middle of the injector, thus increasing the pressure threshold value depending on the strength.
