Abstract

A találmány tárgya szerkezet belső égésű dugattyús motor szelepe (2)löketének változtatására 0-lökettől a névleges löket közötti bármelyértékre, amelynél szelepmozgató bütyköstengely (27) van, amelynek abütyke (28) egykarú szelepemelő (19) érintkező felületével (24) állállandó érintkezésben, az egykarú szelepemelő (19) elmozdulásmentescsapon (23) van ágyazva egyik végénél, a másik, elforduló végénlengőcsap (9) van elrendezve, mely az elmozdulásmentes csappal (23)párhuzamos tengelyű, amelyen lengő emelőkar (6) egyik vége vanágyazva, másik végén a mozgatott szelep (2) szárára (4) felfekvőnyomófelütet (7) van kiképezve. A találmány szerint a lengő emelőkar(6) a lengőcsap (9) körüli elfordítására támasztófetülettel (13) vanellátva, amely elmozdíthatóan ágyazott vezérlőtustkó (32)vezérgörbéjével (35) van folyamatos érintkezésben, amelynekalapállásához a szelep (2) 0-löketű állása másik szélső állásához anévleges löketű állása van rendelve, a közbenső mindenkori álláshoz aközbenső-löketnagyság van rendelve, a vezérlőtuskó (32) aszelepemelést vezérlő motorvezérlő/szabályozó mozgató elemmel állösszeköttetésben.
