Abstract
A találmány tárgya befecskendezőszelep, főleg belső égésű motorhozvaló befecskendezőszelep. A befecskendezőszelep magában foglallegalább egy fúvókamodult (3), ami befecskendezőfúvókával és tápnyomásalatt álló közeg számára tápvezetékkel rendelkezik, valamint egyszelepvezérlő modult (2), ami a fúvókamodullal (3) működtetőkapcsolatban áll, és legalább egy szelepzáró tagot (16), amire atápnyomás hat, és piezoelektromos működtetővel (12) rendelkezik, ami aszelepzáró tag (16) működtetésére szolgál, és rugóval (21) aszelepzáró taggal (16) ellentétes irányban elő van feszítve; apiezoelektromos működtető (12) kivezérlése szelepvezérlő egységgeltörténik, ami megszab egy kivezérlési gradienst. A kivezérlésigradiens a tápnyomástól függő mennyiség. Ó
