Abstract
Prezenta inventie se refera la un dispozitiv de comanda pentru roti directoare care este constituit, în principal, dintr-un element de comanda care sesizeaza variatiile în mers ale sistemului principal de directie ale vehiculului. Prezenta inventie are un cilindru hidraulic care prezinta în zona liniei centrale un tronson în care pistonul nu mai este etans si permite fluidului din fata si din spatele pistonului sa fie transvazat printr-o conducta de derivatie într-un rezervor pentru orice deplasare a pistonului în zona tronsonului cu diametru mai mare, într-o prima varianta constructiva, cilindrul hidraulic include o carcasa cilindrica cu un tronson cu diametru mai mare în care se deplaseaza un piston cu miscare alternativa, conducta de derivatie fiind situata pe linia centrala a cilindrului la mijlocul tronsonului cu diametru mai mare în care pistonul nu mai ghideaza etans, în a doua varianta constructiva într-un cilindru hidraulic cu dubla actiune se deplaseaza un ansamblu piston format dintr-un corp de piston care prezinta un canal circular cu sectiune în forma de pîlnie, astfel încît sa formeze o camera inelara care comunica cu cele doua fete opuse ale pistonului prin intermediul unor canale care pot fi închise de catre un disc supapa aflate sub actiunea cîte unui arc elicoidal, miscarea discurilor supapa fiind limitata de catre un element elastic opritor, în cilindru, în dreptul canalului inelar, în zona liniei centrale fiind amplasata o conducta de derivatie care conduce fluidul deversat la un rezervor.
