Abstract

Purgeur pour une installation hydraulique qui s'ouvre automatiquement lors de la mise en pression initiale pour permettre à l'air et aux autres gaz de s'échapper et qui se referme automatiquement après que l'air a éte expulsé quand l'huile hydraulique afflue, du fait de la viscosite de ce dernier est beaucoup plus grande que celle de l'air ou des gaz. Le cylindre hydraulique 10 comporte un alésage ou un canal 12 qui débouche dans cavité 11 et qui est adapté à recevoir le purgeur, désigné en son entier par 13. A l'extérieur de l'alésage 12, on voit un siège conique 14, un contre-perçage taraudé 16 et une face d'extrémité 17 conçue pour ménager un intervalle de ventilation pour le purgeur quand celui-ci est monté. Application à toutes les installations et à tous les circuits hydrauliques devant être purgés pour les débarrasser de l'air.Drain valve for a hydraulic installation that opens automatically upon initial pressurization to allow air and other gases to escape and which closes automatically after air has been expelled when hydraulic oil flows , due to the viscosity of the latter is much greater than that of air or gases. The hydraulic cylinder 10 comprises a bore or a channel 12 which opens into cavity 11 and which is adapted to receive the bleeder, designated in its entirety by 13. Outside the bore 12, there is a conical seat 14, a threaded counterbore 16 and an end face 17 designed to provide a ventilation gap for the trap when the latter is mounted. Application to all installations and to all hydraulic circuits which have to be purged in order to free them of air.
