Conduit connection assembly with pressure relief

A turbocharger comprising a conduit component being assembled to another conduit component;

• wherein the conduit component has a first mating structure for mating with a second mating structure of the another conduit component;
• wherein the first mating structure further comprises:
• a pressure relief opening for being arranged in communication with an intermediate space between two spaced sealing members of a sealing arrangement for sealing between the first mating structure and the second mating structure;
• wherein the two spaced sealing members define the intermediate space in an assembled state;
• and
• wherein the conduit component is positioned on an upstream side of a turbine in the turbocharger, wherein the turbocharger comprises a fluid line, which at a first end is in communication with the pressure relief opening and at a second end is positioned in an exhaust line on a downstream side of the turbine.

A conduit connection assembly comprising;

• a first conduit component having a first mating structure;
• a second conduit component having a second mating structure being mated with the first mating structure;
• a pressure relief opening:
• a sealing arrangement for sealing between the first mating structure and the second mating structure;
• wherein the sealing arrangement comprises at least two spaced sealing members defining an intermediate space;
• and
• wherein the pressure relief opening is arranged in communication with the intermediate space between the two spaced sealing members;
• a fluid line, which at a first end is in communication with the pressure relief opening and at a second end is in communication with an environment having a pressure being lower than a pressure prevailing on an internal side of the conduit connection assembly during an operational fluid;
• wherein the environment having the pressure being lower than the pressure prevailing on the internal side of the conduit connection assembly, is separate from a main conduit for the operational fluid to be conveyed between the first conduit component and the second conduit component, and
• wherein the environment having the pressure being lower than the pressure prevailing on the internal side of the conduit connection assembly is formed by a space for collection of a fluid.
