Disclosed are a nozzle assembly and a vacuum ejector including the same. The nozzle assembly of the vacuum ejector generates a negative pressure in a suction port by discharging gas, which flows in through an inlet port, through a discharge port. According to the present invention, the nozzle assembly includes: a nozzle; and a valve body opening and closing a suction channel. The nozzle includes: an inlet connected to the inlet port, wherein the gas flows inside; an outlet connected to the discharge port, wherein the gas which flows in through the inlet is discharged through the outlet; a suction unit connected to the suction port; a moving channel connecting the inlet and the outlet; and the suction channel connecting the suction unit and the moving channel. The valve body seals the suction channel by being formed in a direction crossing the longitudinal direction of the moving channel. According to the present invention, the valve body is formed in the direction crossing the longitudinal direction (a flowing direction of a driving fluid) of the moving channel. So, a suction fluid can smoothly flow into the moving channel, and resistance caused when the suction fluid flows can be minimized. |
