FIELD: oil and gas industry.

SUBSTANCE: invention relates to equipment for cleaning inner cavity of tanks, in particular, railway cisterns from viscous oil deposits. Ejector device is made in form of hydraulic monitor and comprises at least one hollow bar having at its end and ejector adapter. Nozzle comprises a housing with a cover, which includes inner cavity and outer annular chamber communicated via feed holes, at least three support disc with branch pipes, equipped with nozzles. Inner cavity of housing is communicated with hollow rod. Support discs are equipped with guide holes. Pipes are arranged on support discs at an angle to normal of outer annular chamber of housing. Guide holes in discs are arranged to normal of outer annular chamber of housing at an angle, value of which is greater than value of installation angle of pipes. Nozzles have outlets with an ellipse-like section and are installed on pipes through rotating discs coaxially with nozzles to rotate about a common axis. Hydraulic monitor is mounted on rod, on which there is a chain gear and is installed with possibility of longitudinal movement of carriage. On upper end of rod is fixed a wheel for movement of chain transmission, and on lower end of rod there is a bar pivotally installed with possibility of adusting angular position, said bar being connected by means of lever with carriage.
