PURPOSE: An ejector is provided to minimize impact by inertia which is delivered to a target object, impact caused by colliding with the inner surface of an suction chamber, and impact caused by a contact with fluid, thereby preventing damage to the target object. CONSTITUTION: An ejector comprises a body(100), a suction tube(200), and a sealing unit(400). The body of a pipe shape includes a coupling pipe unit(120), which is communicated to an inner suction chamber in a longitudinal direction, and a discharging pipe unit. A fluid supply pipe(140) is formed in a lateral side of the body. The suction tube is screw-joined to the coupling pipe unit so that one end of the suction tube is closely adhered to an inlet of the discharging pipe unit while a position changing is possible. The sealing unit includes a cover(410) and a sealing member(420). A stepped portion(122) is formed in an inlet side of the coupling pipe unit. Through-holes are formed in the center of the cover so that the suction tube is inserted. The sealing member is formed of an elastic material and press-interposed between the stepped portion and the cover, thereby improving airtightness. |
