The invention relates to a jet pump type ejector (36) for a turbomachine, including a duct (40) through which a secondary ventilation air flow passes, and a first end of which forms an air intake (42) and a second end of which forms an air outlet (44), the two nozzles (38) for spraying a primary air flow being mounted in the duct which defines a mixer (46) and a diffuser (48) downstream from the nozzle, said two nozzles being parallel and adjacent to one another, the mixer including two substantially planar longitudinal walls, bottom (52) and top (54) respectively, connected to one another by two side walls (56) having a semi-circular cross-section, in which the radius of curvature R2 is centred on the axis of a nozzle, the centre-to-centre distance (1) of the nozzles (38) being substantially equal to π/2.R2.
