Ejector

An ejector comprising:

• a nozzle that is adapted to depressurize and inject fluid, which is supplied to the nozzle;
• and
• a body that includes:
• a fluid suction opening that is adapted to draw fluid by an action of the injected fluid, which is injected at a high velocity from the nozzle;
• and
• a pressurizing portion that is adapted to mix the injected fluid, which is injected from the nozzle, and the drawn fluid, which is drawn through the fluid suction opening, such that a mixture of the injected fluid and the drawn fluid is pressurized through the pressurizing portion, wherein:
• at least one of the nozzle and the body is formed by press working;
• the at least one of the nozzle and the body, which is formed by the press working, has a rib that extends in an axial direction of the nozzle and projects radially outward;
• and
• in a predetermined cross section of the at least one of the nozzle and the body, which is perpendicular to the axial direction and includes the rib, the at least one of the nozzle and the body is formed seamlessly as a continuous single piece member.
