Abstract
An ejector device (), e.g., for pumping a gas using a liquid motive fluid, has an injector portion (), and a diffuser portion (), the injector portion () being arranged for injecting a flow of motive fluid from a motive fluid inlet () into an inlet section () of the diffuser portion () thereby to draw a suction fluid from a suction fluid inlet () into the inlet section () of the diffuser portion (). The injector portion () includes a flow-modifying arrangement with at least one rotational deflector element (), e.g., three vanes (VVV) each at a desired twist angle, constructed and arranged to deflect motive fluid into a helical path as it moves over or through the rotational deflector element (), and at least one baffle element (), e.g., a baffle plate (), downstream of the rotational deflector element ().
