Since piezoelectric actuators, especially the bender type, have become low-cost, easy to use, faster and more reliable in operation, they have also attracted a lot of attention in pneumatic control-valve applications. The presented study reports on the experimental development of a pilot-stage valve with two bending piezo-elements attached to a standard pneumatic valve of size ISO 3, 5/2. The most important characteristics of piezo-actuators and the possibilities for their use in pneumatic control valves are discussed, and the features of the developed pilot-stage piezo-actuator valve are presented</dc:description><dc:description xml:lang="sl">Zaradi vse večjih zahtev po boljsih dinamičnih lastnostih in manjši porabi energije pnevmatičnih ventilov, je treba nenehno izboljševati sedanje elektromagnetne aktuatorje, obenem pa raziskati možnosti uporabe alternativnih aktuatorjev. Odkar so piezoelektrična premikala, predvsem upogibna, pridobila na preprostosti oz. cenenosti, hitrosti delovanja in zanesljivosti, so v zadnjih letih pritegnila veliko pozornosti tudi za uporabo pri krmiljenju pnevmatičnih ventilov. V okviru predstavljene raziskave je bil razvit predkrmilni ventil z dvema upogibnima piezoelementoma ter prigrajen standardnemu pnevmatičnemu ventilu velikosti ISO 3, 5/2. V prispevku so prikazane bistvene značilnosti piezoelementov, moznosti uporabe le-teh za krmiljeneje pnevmatičnih ventilov in na koncu analiza ventila s predkrmilnim piezoelementom</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-55GLQJMQ"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-55GLQJMQ" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-55GLQJMQ/03844ee1-c824-498f-b74d-8a99087952e8/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za strojništvo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-55GLQJMQ/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-55GLQJMQ" /></ore:Aggregation></rdf:RDF>
