Abstract

Dispositif comportant une pompe à fonctionnement intermittent, dont l'arrêt est commandé par un piston. La pompe 1 comporte un piston 2 poussé par un ressort 3 et entraîné par l'arbre à cames 4. Sachambre 8 est reliée à la tubulure d'aspiration 9 et à la tubulure de refoulement 11. Celle-ci mène à un accumulateur de pression 13 et, par la tubulure 14, à la chambre 15 du tiroir 16. La tubulure 14 est surveillée par la soupape d'inversion 17 comportant un piston 18 et une soupape 19. Le tiroir 16, qui deux profils de commande 20 et 21, est maintenu normalement gauche par le ressort 22. Le profil 20 surveille la liaison 23 avec le réservoir 24, et le profil 21 se trouve dans la liaison 25 avec l'aspiration, liaison entre la chambre 26 du piston 27 et le régulateur de pression 28. Le piston 27 peut, par sa tige 29 et son extrémité 30, soustraire le piston 2 à l'action de l'arbre 4 et arrêter ainsi la pompe.Device comprising an intermittent operating pump, the stopping of which is controlled by a piston. The pump 1 comprises a piston 2 pushed by a spring 3 and driven by the camshaft 4. The chamber 8 is connected to the suction pipe 9 and to the discharge pipe 11. This leads to a pressure accumulator 13 and, by the pipe 14, to the chamber 15 of the drawer 16. The pipe 14 is monitored by the reversing valve 17 comprising a piston 18 and a valve 19. The slide 16, which two control profiles 20 and 21, is maintained normally left by the spring 22. The profile 20 monitors the connection 23 with the reservoir 24, and the profile 21 is in the connection 25 with the suction, connection between the chamber 26 of the piston 27 and the pressure regulator 28 The piston 27 can, by its rod 29 and its end 30, withdraw the piston 2 from the action of the shaft 4 and thus stop the pump.
