Abstract
The invention relates to a jet pump collector comprising a convergent duct extending along the longitudinal axis (AX) and comprising an intake opening for a fluid to be withdrawn, this convergent duct having a restriction shape terminated by a reduced end having a smaller cross-section than its intake opening. This convergent duct is equipped with a tube (17) orientated perpendicular to the longitudinal axis longitudinal (AX), this tube (17) comprising an outer portion extending outside of the convergent duct and being terminated by an intake opening (31) for a propulsion fluid, and an inner portion extending in the convergent duct and comprising a plurality of distribution openings (18, 19) for the propulsion fluid which are orientated towards the reduced end.
