We designed and constructed a proportional 4/3 directional continuous acting spool type sliding valve, a simplified model but still with the shape and working parameters resembling real valves. Our investigations of mentionedwater valve are divided on two different test rigs: real scale hydraulic test rig and tribological test rig. Taking into consideration the body accessible information about water power-control hydraulics (PCH), we constructed a simple, double, water and oil hydraulic test rig. We carried out preliminary tribological tests of different material-pairs lubricated with additive-free distilled water. The results of the preliminary tribological tests of different material pairs are described in this paper</dc:description><dc:description xml:lang="sl">Prispevek uvodoma prikazuje smiselnost in področja uporabe vodne pogonsko-krmilne hidravlike (PKH). Zasnovali smo funkcionalni prototip vodnega proporcionalnega 4/3 potnega drsniskega ventila. Naše raziskave omenjenega novega vodnega ventila so razdeljene na dva dela: realno hidravlično preizkušanje in tribološko preizkušanje. V prispevku je prikazana zasnova in funkcijska shema novega dvojnega preizkuševališča za vodno in oljno pogonsko-krmilno hidravliko. Prikazan je osnutek postopka preizkušanja na realnem hidravličnem preizkusevališču. V zadnjem delu prispevka je tribološko preizkuševališče, "pin-disk" naprava, preizkušeni pari materialov mazani z destilirano vodo, rezultati obrabe in merjenja koeficienta trenja</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-4Q4PNOMG"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-4Q4PNOMG" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-4Q4PNOMG/7be7f799-3808-40e0-812c-1566a9ecc2af/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-4Q4PNOMG/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-4Q4PNOMG" /></ore:Aggregation></rdf:RDF>
