Abstract

Distributeur hydraulique à temporisation. Lorsque le tiroir 16 est déplacé d'une position neutre à une position extrême, il y a un écoulement de liquide temporisé d'une des deux chambres 29 et 30 à l'autre chambre par l'intermédiaire du passage 39 où l'un des deux clapets 40 et 41 est fermé. Au retour vers la position neutre, les tiges 44 peuvent être attaquées plus ou moins tôt par les disques 33 et 36 ce qui permet soit l'absence de temporisation, soit la présence d'une temporisation totale ou partielle. Applications : distributeurs hydrauliques.
