Abstract

Inventia se refera la o pompa cu roti dintate cu debit variabil utilizata în actionarile hidraulice ale masinilor si utilajelor. Pompa, conform inventiei, este alcatuita dintr-o carcasa, prevazuta, la interior, cu doua roti dintate având fiecare practicate niste canale radiale corespunzatoare fiecarui gol dintre dinti precum si câte un sertar axial reglabil ca pozitie. Fiecare sertar axial eate prevazut cu mai multe canale circumferentiale de dimensiumi diferite, ambele sertare fiind reglate axial prin niste tije prevazute la capatul dinspre sertar cu câte o bila sertizata. Ambele tije sunt fixate într-un suport prevazut cu o rola pe care apasa o bucsa tronconica, montata pe o tija cu piston, piston aflat în legatura directa cu gura de refulare a pompei, celalalt capat al tijei cu piston fiind apasat de un arc reglabil.The invention relates to a variable displacement gear pump used in the hydraulic drives of machines and machines. According to the invention, the pump consists of a housing provided with two gears on the inside, each of which has radial channels corresponding to each gap between the teeth and an axially adjustable drawer as a position. Each axial drawer is provided with a plurality of circumferential grooves of different dimensions, both of which are axially adjustable by means of some rods provided at the end of the drawer with a serrated ball. Both rods are fixed to a support provided with a roller that presses a truncated bush mounted on a piston rod, a piston directly connected to the pump discharge mouth, the other end of the piston rod being pressed by an adjustable spring .
