Abstract

Prezenta inventie se refera la un mecanism-motor utilizat în special la motoarele cu ardere interna, pentru varierea cursei pistonului prin modificarea razei manivelei, în vederea modificarii ciclice a volumului camerei de ardere, în concordanta cu cerintele proceselor ciclului motor. Pentru solutionarea acestei cerinte s-au montat niste excentrice pe fusurile manetoane, care, prin intermediul unui lant cinematic din angrenaje, care asigura sensul si raportul de transmitere a miscarii, sunt rotite cu jumatate din viteza unghiulara a arborelui cotit, ceea ce asigura varierea ciclica a razei constructive a manivelei cu valoarea excentricitatii. Dispozitivul permite si varierea raportului de comprimare sau defazare a proceselor prin lantul cinematic de comanda care poate imprima excentricelor o anumita pozitie unghiulara necesara pentru toti cilindrii, fara a mai avea o variatie ciclica. Dipozitivul poate fi aplicat atît la motoarele cu aprindere prin scînteie, cît si la cele cu aprindere prin comprimare, atît de conceptie nou, cît si la cele din fabricatie curenta.
