Abstract

A találmány egyrészt berendezés virtuális szelepként buborékalkalmazására folyadék (26) kilövellésére szolgáló mikroinjektorban,amely berendezés tartalmaz folyadékot (26) befogadó kamrát (14), akamrával (14) közlekedő kapcsolatban álló, a kamra (14) felettelhelyezett nyílást, a kamra (14) folyadékkal (26) feltöltöttállapotában a kamrában (14) egy első buborékot (30) fejlesztő eszközt,amely első buborékot (30) fejlesztő eszköz a nyílás mellett és a kamra(14) felett van elhelyezve, valamint a kamra (14) folyadékkal (26)feltöltött állapotában az első buborék (30) kifejlesztését követően akamrában (14) egy második buborékot (32) fejlesztő eszközt a kamrából(14) folyadék (26) kilövellésére, amely második buborékot (32)fejlesztő eszköz a nyílás mellett és a kamra (14) felett vanelhelyezve. A találmány másrészt a fenti berendezés azzal akülönbséggel, hogy tartalmaz a kamrával (14) közlekedő kapcsolatbanálló és a kamrát (14) folyadékkal (26) ellátó elosztót (16), és azelső buborékot (30) fejlesztő eszköz és a második buborékot (32)fejlesztő eszköz a kamrán (14) kívül van elhelyezve, ahol a másodikbuborék (32) a kamrában (14) lévő folyadéknak (26) a nyílásonkeresztül történő kilövellődését okozza. A találmány továbbá eljárásnyílással rendelkező mikrocsatornából folyadék (26) kilövellésére,amelynek során a folyadékkal (26) teli mikrocsatornában a nyílásmellett egy első buborékot (30) fejlesztenek, a mikrocsatornában anyílás mellett egy második buborék (32) fejlesztésével amikrocsatornában túlnyomást hoznak létre folyadék (26) kilövellésére,ahol a második buborék (32) fejlesztését az első buborék (30)fejlesztése után végzik, és ahol az első buborék (30) és a másodikbuborék (32) a nyílás mellett helyezkedik el, az első buborékot (30) amikrocsatornába történő folyadékbeáramlást gátoló virtuális szelepkéntmegnövelik a mikrocsatornában, valamint a második buborékot (32)megnövelik a mikrocsatornában, és ezáltal az első buborék (30) és amásodik buborék (32) egymáshoz közelítve hirtelen véget vet a nyílásonát történő folyadékkilövellésnek. A találmány másrészt a fenti eljárásazzal a különbséggel, hogy az első buborékot (30) és a másodikbuborékot (32) összeolvasztják a folyadék (26) nyíláson keresztülikilövellésének hirtelen megszüntetésére.
