Abstract
The invention relates to an ejector arrangement (1, 40) comprising a housing (11) and at least two ejectors (2, 3, 41, 42) arranged in said housing (11) along a common axis (13). Each ejector (2, 3, 41, 42) has a motive inlet (4, 5), a suction inlet (6, 7), an outlet (8, 9) and a valve element (23, 24, 43, 44). The task of the invention is to provide an ejector arrangement that allows for a good control of the mass flow of fluid through the ejector arrangement while keeping the construction simple. According to the invention the above task is solved in that the ejector arrangement (1, 40) comprises a common actuator (25, 55), that is arranged to engage at least two of the valve elements (23, 24, 43, 44) to open the motive inlets (4, 5).
