Abstract
Le dispositif de commande est précédé d'un régulateur de pression soumis d'une part à la pression en amont de l'étranglement 15, 115, réglable par le levier 14 et d'autre part à la pression en aval de l'étranglement et à l'action d'un ressort 38, 138. Une soupape d'inversion 19 relie à la canalisation 20 celle des canalisations 18, 118 qui correspond à l'utilisateur dont la pression de charge est la plus forte. Une soupape de dérivation 21 soumise à l'action de la pression dans la canalisation d'alimentation 3 et à l'action combinée de la pression dans la canalisation 20 et d'un ressort 23 détermine de combien la pression fournie par la pompe doit être supérieure à la pression de charge la plus forte. Alimentation de dispositifs hydrauliques, notamment de servo-moteurs.The control device is preceded by a pressure regulator subjected on the one hand to the pressure upstream of the constriction 15, 115, adjustable by the lever 14 and on the other hand to the pressure downstream of the constriction and to the action of a spring 38, 138. A reversing valve 19 connects to the pipe 20 that of the pipes 18, 118 which corresponds to the user whose load pressure is the highest. A bypass valve 21 subjected to the action of the pressure in the supply line 3 and the combined action of the pressure in the line 20 and a spring 23 determines how much pressure supplied by the pump should be. greater than the highest charging pressure. Supply of hydraulic devices, in particular servo-motors.
