Abstract
An ejector has an interior nozzle, an exterior nozzle, a suction part, a mixing part and a diffuser part. The interior nozzle and the exterior nozzle are arranged coaxially with each other. A driving fluid is supplied to the interior nozzle and/or the exterior nozzle. The suction part is arranged on an outer periphery of the exterior nozzle and sucks a suction fluid by a driving fluid jet ejected from the interior nozzle and/or the exterior nozzle. A mixing part mixes the driving fluid jet with the suction fluid, and supplies a mixture fluid. The diffuser part reduces a flow speed of the mixture fluid and ejects the mixture fluid outside. An outlet part of the interior nozzle is arranged at an upstream side of the ejector more than an outlet part of the exterior nozzle along the axial direction of the ejector.
