ABSTRACT:
The present invention relates to a centrifuge with a turbine system for hydraulic control and the like, wherein the system comprises an annular member having a groove mounted to slide in a housing hollowed in the lower face of the bowl 4, this groove member being fast with a support wedged on the conical bearing surface of the shaft. The liquid arrives through the ports in a plate whose ports discharge into the groove. The liquid injected in 14 raises a movable bowl member and uncovers the ports for draining the sludge from the bowl. By overflow, a drain valve is suppled of the groove into another hydraulic path with liquid to open the bowl. The bowl 4 may thus be withdrawn from the shaft by being lifted without dismantling of its lid. The invention is applicable to centrifuges with hydraulic controls.
