Abstract

Dans l'installation représentée, la source de pression comporte deux pompes volumétriques 24, 53 dont la pression est reliée en permanence avec une conduite principale 21, tandis que la pompe 53 est une pompe auxiliaire dont le refoulement 56 peut retourner à la bâche 23, par l'effet du distributeur 57 lorsque le débit de la pompe principale 24 couvre en totalité la demande de fluide. Le régulateur 27 assure une alimentation sous haute pression des organes de commande hydraulique 19; le surplus de débit alimente un circuit de lubrification 50 et le convertisseur de couple 12, sous une pression qui par la conduite 46 règle le débit des pompes 24, 53.In the installation shown, the pressure source comprises two positive displacement pumps 24, 53, the pressure of which is permanently connected to a main pipe 21, while the pump 53 is an auxiliary pump whose discharge 56 can return to the tank 23, by the effect of the distributor 57 when the flow rate of the main pump 24 completely covers the demand for fluid. The regulator 27 provides a high pressure supply to the hydraulic control members 19; the excess flow feeds a lubrication circuit 50 and the torque converter 12, under a pressure which, via the pipe 46, regulates the flow of the pumps 24, 53.
