Abstract
A találmány tárgya üzemanyag-befecskendező szerkezet (1) belső égésűmotorokhoz, nagynyomású üzemanyag-forrásból (8) üzemanyaggal elláthatóbefecskendező fúvókával és azt vezérlési térbeli (6) nyomástól függőennyitó és záró működtetőelemmel (9), a vezérlési térbe (6) torkollóelső nagynyomású vezetékkel (7), és a vezérlési tértől (6) kiindulólefolyócsatornával (10), amely szeleptag (3) záróelemével (13)lezárható, továbbá a fúvókatérbe vezető nagynyomású odavezetéssel (19,20, 21, 22), amely a szeleptag (3) első szelepülékével (4) lezárható,miközben a szeleptag (3) működtető egység segítségével meghatározottemelkedési úttal mozoghat, amelynek függvényében a záróelem (13)zárási állás és a vezérlési teret (6) tehermentesítő ésbefecskendezést megengedő nyitási állás között mozoghat.
