    • A nozzle chip (3') for ejecting a liquid such as in an electrospray device is built from a substrate chip having grooves (5, 7) on a top surface. A lid (25) is attached to the top surface closing the grooves to form channels one of which has an open outlet end (9). At the outlet end a nozzle is formed at or attached and it has an outlet opening from which the liquid is to be ejected. Alignment recesses (13, 15) are made at edges of the substrate chip and they are accurately positioned in relation to the outlet opening, the alignment recesses allowing an accurate mounting of nozzle chip giving the outlet opening of the nozzle a reproducible position in the device where it is to be used. At the outlet end a recess (17) in the substrate chip can be provided and the nozzle can then be located in the recess to mechanically protect it.
    • 用于喷射诸如电喷雾装置中的液体的喷嘴芯片(3')从在顶表面上具有凹槽(5,7)的衬底芯片构建。 盖(25)附接到顶表面,封闭沟槽以形成通道,其中一个具有开放的出口端(9)。 在出口处,喷嘴形成在或附接并且具有出口,液体从该出口开始喷出。 对准凹槽(13,15)在基片的边缘处形成,并且它们相对于出口开口精确地定位,所述对准凹槽允许精确地安装喷嘴芯片,使得喷嘴的出口开口在装置中是可再现的位置 在哪里使用。 在出口端,可以设置衬底芯片中的凹部(17),然后可以将喷嘴定位在凹部中以机械地保护其。
