Hydraulic device used for degassing liquid

The invention discloses a hydraulic device used for degassing liquid, especially used for degassing hydraulic oil. The hydraulic device is provided with a pressure source, and the liquid to be degassed flows out of the pressure source through a nozzle, which is connected with a pipe. The hydraulic device is characterized in that the liquid amount flowing through the nozzle is coordinated with the flow cross section of the nozzle, and the supercavitation function of the downstream of the nozzle is used to generate the liquid beam in the pipe, and the liquid beam is enclosed by a continuous area formed by liquid steam and air. 根据本发明，有种用于对液体除气、尤其是对液压油除气的液压装置，所述液压装置具有压力源，有待除气的液体通过喷嘴从所述压力源流出，管子联接到所述喷嘴上，其特征在于，经由所述喷嘴流动的液体量和所述喷嘴的通流横截面彼此协调，使得通过所述喷嘴下游的超空泡作用在所述管子中产生液体射束，所述液体射束被由液体蒸汽和空气构成的连续区域围住。
