  • METHOD FOR MONITORING A WEAR STATE OF A GAS PATH CONTROL DEVICE, CONTROL DEVICE FOR CARRYING OUT SUCH A METHOD AND ENERGY CONVERSION DEVICE HAVING SUCH A CONTROL DEVICE
    Publication number: 20250020542
    Abstract: A method for monitoring a wear state of a gas path control device of an energy conversion device having a gas path includes the steps of: detecting, in a time-dependent manner, an actuator position of an actuator that is for adjusting an actuating element of the gas path control device; determining at least one wear state parameter based on the actuator position which is detected in a time-dependent manner; and determining the wear state by way of the at least one wear state parameter.

  • 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.
