Abstract

La présente invention concerne un système hydraulique auxiliaire à accumulateur en vue d'augmenter le débit d'une pompe à béton. Le système comprend un circuit de raccordement d'huile pourvu d'un point d'entrée P et d'un point de sortie B entre lesquels est situé un clapet anti-retour. Le système comprend également un accumulateur 10 et une soupape de décharge 12 ainsi qu'un point de sortie T entre le clapet anti-retour 11 et le point P. L'huile sous pression entre par le point P dans l'accumulateur destiné à stocker l'énergie, puis l'accumulateur expulse un autre volume d'huile sous pression via le clapet anti-retour 11. La pression au point B détermine l'état de l'accumulateur 10. La soupape de décharge 12 fixe la pression de décharge et l'huile déchargée retourne au réservoir par le point T. Lorsqu'une vanne de répartition située sur le circuit de fonctionnement est actionnée, l'accumulateur relâche une partie de l'huile sous pression pour répondre à la demande de puissance. Lorsque la vanne de répartition n'est pas actionnée, l'accumulateur fournit également de l'huile sous pression au circuit de fonctionnement. La présente invention offre l'avantage de la stabilité de fonctionnement, notamment de la pompe incorporée au système.
