PURPOSE: A variable capacity type ejector is provided to improve performance of whole system and stabilize operation by easily coping with fluctuation of load on the system. CONSTITUTION: An ejector includes an intake part(50); a nozzle part(60); a variable area part(70); and a diffuser part(80). The intake part is where intake fluid flows in. The nozzle part is connected with an inside of the intake part to spray high pressure driving fluid to flow the intake fluid. The variable area part is connected with the intake part for the intake fluid and the driving fluid to mix with each other and pass and is formed so that length and area of transection are variable according to fluctuation of load of fluid. The diffuser part is connected with an end of the variable area part to pressurize and discharge mixed fluid. |
