The invention provides an adjustable ejector. The adjustable ejector comprises a regulator, sub-ejectors, a first ejection gas fluid inlet and a first ejected gas fluid inlet, wherein the sub-ejectorsare arranged in an annular array mode; the sub-ejectors are connected with the regulator respectively; the first ejection gas fluid inlet and the first ejected gas fluid inlet are both communicated with the sub-ejectors; and outlets are formed in the end parts, far away from the regulator, of the sub-ejectors. According to the adjustable ejector provided by the invention, the whole ejector can keep higher ejection efficiency, and the adaptability of the whole ejector under different ejection fluid flow and pressure conditions and the adaptability of the whole ejector under working condition change conditions are improved. 本发明提供一种可调引射器，包括调节器、子引射器、第一引射气流体进口和第一被引射气流体进口。其中，子引射器呈环形阵列的方式布置。子引射器分别与调节器连接。第一引射气流体进口和第一被引射气流体进口均与子引射器连通。子引射器上远离调节器的端部设有出口。本发明提供的可调引射器，能够使得整个引射器保持较好的引射效率和提高整个引射器在不同引射流体流量和压力条件下得适应性以及工况变化条件下的适应性。
