ABSTRACT:
An obturator device for a pressurized hydraulic damper tube of the single tube type in which slides a piston having an axial piston rod. The obturator device includes a plug, a seal, a fixing mechanism and a cylindrical guide whose central opening guides axial movement of the piston rod. The guide has a guide base and an axial peripheral wall defining a circular housing for supporting and centering the seal and the plug. The seal and plug can be fully received with the circular housing in one embodiment of the invention. The base has a plurality of perforations arranged along a circular path positioned at the bottom of an annular groove formed in the base's upper side. The plug has a central opening whose diameter is greater than the diameter of the piston rod of the tube to define a radial clearance preventing mechanical contact between the plug and the piston rod during operation of the damper. The plug also has a circular housing around its central opening to receive part of the seal sandwiched between the plug and guide device.
