Suction jet pump
View Patent ↗A suction jet pump has a fuel line, a propulsion jet nozzle, an intake region, a mixing tube, and a diffuser. The propulsion jet nozzle and the mixing tube are oriented rectilinearly with respect to one another. As viewed in the direction of flow, the diffuser has a course which differs from the course of the mixing tube.
1. A suction jet pump comprising:
a propellant line;
a propulsion jet nozzle fluidically downstream of the propellant line;
a suction region;
a mixing pipe arranged fluidically downstream of the suction region and orientated in a linear manner with respect to the propulsion jet nozzle;
a diffuser having an uninterrupted concave surface facing an outlet of the mixing pipe and arranged to surround the mixing pipe in a coaxial manner, wherein the diffuser, when viewed in a flow direction, has a path that deviates from a path of the mixing pipe; and
a plurality of individual webs configured to support the diffuser that extend from an outer periphery of the diffuser into a region of the propulsion jet nozzle.
2. The suction jet pump as claimed in claim 1 , wherein the diffuser has a curved path.
3. The suction jet pump as claimed in claim 1 , wherein the diffuser is substantially funnel shaped and an output of the diffuser is arranged along an axis of the diffuser.
