Indicator for Indicating the Occurrence of a Pressurized Fluid Leak in a Vent Chamber of a Pressurized Fluid Apparatus

An indicator, for indicating an occurrence of a leak of pressurized fluid in a vent chamber of a pressurized fluid apparatus, the indicator comprising:

• a support tube, comprising:
• a connection opening, configured to be fluidically connected to the vent chamber of the pressurized fluid apparatus;
• and
• an external opening, configured to open out to an outside of the pressurized fluid apparatus;
• and
• a poppet, arranged in the support tube and movable with respect to the support tube, between an initial position and a signaling position, under the effect of an overpressure occurring at the connection opening, compared with the external opening, the poppet being positioned further away from the connection opening in the signaling position than in the initial position, to indicate the occurrence of the leak of pressurized fluid into the vent chamber when the poppet is in the signaling position.
