Intake conduit element and compressor arrangement therefrom

摘要

Intake manifold element (1) having a tubular section (3) through which a first fluid (A) can flow in a proposed flow direction (A′) via a flow channel (4) from an inlet (4a) to an outlet (4b) of the same, said tubular section being provided for arrangement on a compressor inlet (11a) of a turbocharger, characterized in that the flow channel (4) has a nozzle-shaped design, wherein its cross-section which the fluid can flow through is tapered in the flow direction (A′), wherein the tubular section (3) forms a chamber (6) adjacent to the nozzle-shaped flow channel (4) which serves as flow path from an inlet (6a) to an outlet (6b) for the aspiration of a second fluid (B), the pressure level of said chamber on the inlet (6a) being dependent on the pressure level of the first fluid (A) on the outlet (4b) of the flow channel (4) via communicating outlets (6b, 4b) of the chamber (6) and the flow channel (4).

1. An intake manifold element having a tubular section through which a first fluid can flow in a proposed flow direction via a flow channel from an inlet to an outlet of the same, said tubular section being provided for arrangement on a compressor inlet of a turbocharger, wherein the flow channel has a nozzle-shaped design, wherein its cross-section which the fluid can flow through said cross section is tapered in the flow direction, said tubular section forming a chamber adjacent to the nozzle-shaped flow channel which serves as flow path from an inlet to an outlet for the aspiration of a second fluid, the pressure level of said chamber on the inlet being dependent on the pressure level of the first fluid on the outlet of the flow channel via communicating outlets of the chamber and the flow channel;
wherein the chamber is an annular chamber having an outlet that concentrically surrounds the outlet of the nozzle-shaped flow channel; wherein the compressor inlet includes a first inlet opening and a second inlet opening that concentrically surrounds the first inlet opening; wherein the outlet of the annular chamber and the first inlet opening of the compressor have a respective one of two diameters that are equal to one another; wherein the outlet of the annular chamber and the first inlet opening of the compressor are disposed along a common middle axis of symmetry.
