Abstract: A working machine such as a hydraulic excavator is provided with a working apparatus (6) including a boom (7) pivotally mounted on the body (1, 2) of the working apparatus (6) and a boom-cylinder hydraulic system for the working apparatus (6). The hydraulic system includes an actuator (10) for moving the boom (7) up and down and a directional selecting valve (16). The directional selecting valve (16) is arranged to effect selective switching of the feed of a pressurized working fluid to and the discharge of working fluid from with respect to the rod-side (10A) and the bottom-side hydraulic chamber (10B). The hydraulic system further includes a device (21:51, 53, 55:51, 53, 63:51, 53, 72:101, 102, 104:53, 141, 142:53, 151, 152) for relieving the pressure of the bottom-side hydraulic chamber (10B) of the actuator (10). This release device is connected to the bottom-side hydraulic chamber (10B) of the actuator (10) via a hydraulic circuit (13-16). When the pressure in the bottom-side hydraulic chamber (10B) changes from rise to fall, the pressure is released to a low-pressure side of the hydraulic circuit (13-16), thereby suppressing oscillation of the boom (7).

Abstract: Selon ce procédé, les micro-organismes sont cultivés et se développent sur une trajectoire de mise en contact (1) où l'on introduit les eaux usées à nettoyer et une quantité correspondante d'air (2) de manière à créer les conditions optimales pour ces micro-organismes. Une partie des micro-organismes qui quittent la trajectoire de mise en contact (1) après s'être développés au mieux dans l'eau chargée sont ramenés dans cette trajectoire de mise en contact (6), ce qui permet d'avoir toujours à disposition les micro-organismes qui sont le mieux adaptés à l'eau à purifier et de disposer également de quantités suffisantes de ces micro-organismes sains. On prélève en outre, loin de la trajectoire de mise en contact (1), une petite quantité d'eaux usées servant d'indicateur, que l'on introduit dans la région où les micro-organismes sont cultivés (17); on constitue ainsi un système de prédétection qui permet de préparer à temps le développement des micro-organismes. Grâce à ce procédé et au dispositif pour sa mise en oeuvre, on obtient un degré de purification uniforme. On peut en outre faire varier plusieurs facteurs de modification, séparément ou collectivement, en fonction des conditions changeantes: l'apport en éléments nutritionnels peut en effet être modulé, les micro-organismes sont adaptés au mieux aux conditions et très variés, et l'apport d'oxygène, autrement dit l'efficacité de l'aération, est réglable.
