    • A centrifugal pump comprising a pump body (1) housing an impeller (3) keyed onto a motor shaft (4) and provided with a suction mouth (7) and a discharge mouth (8) capable of being made to communicate with, respectively, a suction pipe (9) and a discharge pipe (10). Between the suction mouth (7) and the suction pipe (9) there is provided a chamber (22) that communicates with a tank (11) situated at a level higher than the level of the pump, said tank being interposed between the discharge mouth (8) and the discharge pipe (10) and in communication with both of them and communicating also with the chamber (22) through a recirculation duct (28) having a section smaller than the section of the suction pipe (9). Between the tank (11) and the chamber (22) there is also provided means (13) for cutting off the flow that are controlled by the pressure existing in the tank to automatically cause the liquid to be recirculated in the tank to automatically cause the liquid to be recirculated through the chamber 822) and into the pump whenever the pressure in the tank drops below a predetermined value.
    • 一种离心泵,其包括容纳键入电动机轴(4)并设置有吸嘴(7)和排出口(8)的叶轮(3)的泵体(1),所述吸嘴能够分别与所述泵体 吸入管(9)和排出管(10)。 在吸嘴(7)和抽吸管(9)之间设有一个与位于高于泵水平高度的罐(11)连通的腔室(22),所述罐体位于排出口 (8)和排放管(10)连通并且与它们连通并且通过具有小于吸入管(9)的部分的部分的再循环管道(28)与腔室(22)连通。 在罐(11)和室(22)之间,还设置有用于切断由存在于罐中的压力控制的流动的装置(13),以自动地使液体在罐中再循环,以自动地引起 每当罐中的压力下降到预定值以下时,进入泵中。

    • A system for the controlled administration of a substance by means of an infusion device implanted in the human body comprising an implantable unit (200) for detecting a shortage or an excess of such substance or a physiological parameter correlatable to the shortage or excess of such substance, an infusion group of this substance (100) implantable in the peritoneal cavity and comprising a central control unit (105) for processing data received from the detection unit (200) in order to generate command signals for the release of the substance in the intraperitoneal cavity, energy storage means (106) to power said infusion group (100). The system also comprises a carrier of said substance (500) adapted to be ingested in order to passively reach the duodenal lumen, made of perforable material resistant to gastric acids and with parts in magnetizable metal, and a refilling device (103) for refilling the infusion group (100) with said substance, comprising a magnetic reversible docking group (113) for said carrier (500), facing the duodenal lumen and actuable when said carrier reaches a predetermined distance therefrom, and means (120) for drawing the substance from said carrier communicating with suction means (110) of said infusion group (100).
