VENTILELEMENT ZUR VERWENDUNG IN EINEM TINTENSTRAHLDRUCKKOPF. |
摘要 |
<p>A micro-mechanical valve element has a valve member formed by a plate member (11), and a tongue (12). A fine slit (13) separates the tongue (12) from said plate member (11) at three sides so that tongue (12) is movable. The valve element also includes a valve seat formed by a flat plate portion (21), with an opening (22) and stop members (23). The stop members (23) project into the opening (22) and face the tongue (12) of the valve member. the valve element is formed by a process of laying layers of metal on a substrate (31) of glass, forming resist pattern on selected ones of the metal layers, and subsequently removing the substrate, unwanted portions of the metal layers, and the resist patterns by etching methods.</p> |
