  • Relief valve
    Patent number: 9624822
    Abstract: A relief valve for turbines of exhaust turbochargers. Hot exhaust gas flows against this type of relief valves and the relief valves heat up significantly. Sensitive components such as the springs or the membrane can be damaged as a result. The relief valves are normally designed so that the membrane and a radiation panel are adjacent to a first chamber. Air is continuously guided through the first chamber in order to specifically cool the membrane and protect the membrane from excessive heating.
