Abstract

L'invention se rapporte aux relais de pression hydraulique. Le relais comporte un corps 1 dans lequel se déplace un plongeur 3 soumis à l'action d'un ressort 6. Le plongeur comporte une partie rétrécie 10 située dans une chambre de travail 13 dans laquelle débouchent un conduit d'arrivée de pression principale et un conduit de retour 8. Un conduit 14 de pression à contrôler relie la chambre 13 à une enceinte 2 située sous le plongeur. Application : machines-outils à commande hydraulique.
