The hydraulic damper has a fluid section (4) separated from a pneumatic section (5) by an elastic membrane (2) and with the pneumatic section linked to atmosphere via a porous plug (10). The plug is made of porous ceramic and has a concave shape facing the membrane, to support the extended membrane. The plug has a shaped extension (9) to sit in the air duct (6) located in a sealing plug (8) for the damper.
