Fluid inlet for introducing a hot fluid into a hollow structure
First Claim
1. A fluid inlet for introducing a hot fluid into a hollow structure, comprising:
- a hollow structure for conducting a stream of a fluid;
an inlet feed connection to introduce a hot fluid into the hollow structure; and
an insert mounted inside the hollow structure having a wall surrounding the inlet feed connection to shield the hollow structure from hot fluid introduced through the inlet connection;
wherein the inlet connection has a higher thermal stability than the hollow structure and is heat-resistant relative to said hot fluid, and wherein the insert shields interior walls of the hollow structure against the introduced hot fluid, and the walls of the insert are at least substantially aligned in the flow direction of the introduced fluid.

Abstract
A fluid inlet suitable for introducing a hot exhaust gas into the air intake tract of an internal combustion engine. The exhaust gas is conducted through an inlet pipe (15) and a deflector (18) into the intake pipe or tract (13). A preferably tubular insert (23) is disposed in the intake tract (13). The insert has walls (22) which are oriented in the direction of flow of the aspirated exhaust gas. The fluid inlet reduces the thermal stress on the walls of the intake tract (13) to a minimum and makes high exhaust recovery or recirculation rates possible. In order to additionally support cooling of the insert, the insert may be provided with apertures (26) through which a secondary air current of the intake air which flows through an intermediate chamber (25) can shift to the interior of the tube in order to achieve film cooling of the insert (23).
