Summary:An ejector 80 for a heat recovery or work recovery system, and a heat recovery or work recovery system comprising said ejector 80 are disclosed. The ejector 80 includes: a high-pressure fluid passage 1 including a high-pressure fluid inlet 11 and a high-pressure fluid nozzle 16; a low-pressure fluid passage 2 including a low-pressure fluid inlet 21 and a suction chamber 22 surrounding the high-pressure fluid nozzle 16; a mixing chamber 3 in fluid communication with the high-pressure fluid passage 1 and the low-pressure fluid passage 2 respectively; and a diffusion chamber 4 downstream of the mixing chamber 3; wherein the high-pressure fluid nozzle 16 includes a constricted segment 13, a throat portion 14, and a diffusion segment 15 in sequence, a distal end of the diffusion segment 15 defines a high-pressure fluid outlet, and a peripheral wall of the diffusion segment 15 has a convex arc shape in a longitudinal section. The ejector 80 has higher efficiency as compared to known ejectors.
