| 摘要 |
The invention relates to a relief valve (1) for turbines of exhaust turbochargers. Hot exhaust gas flows against said type of relief valves (1) and said relief valves heat up significantly. Sensitive components such as the springs (12) or the membrane (17) can be damaged as a result. Said type of relief valves (1) are normally designed so that the membrane (17) and a radiation panel (19) are adjacent to a first chamber (23). The aim of the invention is to continuously guide air through said first chamber (23) in order to specifically cool the membrane (17) and protect same from excessive heating. |
