Abstract
The invention relates to an actuating arm (1) for a relief valve (2) of a turbomachine comprising a relief gate (4) intended to be pivoted by the actuating arm between a closed position of a relief air inlet orifice (5) and an open position of said orifice, the orifice being provided in an intermediate housing (6), the relief valve comprising a sealing gasket (7) configured to bear against the relief gate when it is in the closed position, the actuating arm (1) comprising a sensor configured to measure a closed state value of the relief gate (4) when the relief gate (4) is in the closed position and an actuator (17) configured to modify the length of the actuating arm (1) according to the closed state value measured by the sensor.
