FIELD: engines and pumps.
SUBSTANCE: invention relates to jet pumps and can be used in oil-producing units. The ejector installed in the tubing string fitted with the packer with a possibility of its removal from a well contains the housing with radial holes, axial to the housing the nozzle, the suction chamber, the mixing chamber with diffuser, the check valve interacting with a seat, the flow distributor comprising axial, peripheral and radial channels, the sliding assembly containing a sliding grip, the thrust bushing fitted with the filter, and the adapter connected with a head for gripping of the ejector with a mounting tool where channels and boring are made. The tube is in addition built-in into the tubing string, and the thrust ring is fixed on the thrust bushing with shear pins.
EFFECT: improvement of reliability of sitting and efficiency of ejector operation.
