Abstract
The compensator is made separately from the cylinder of the shock absorber, and the two parts are prearranged for the reciprocal coupling with the possibility of articulation around said cylinder and/or around an axis, substantially perpendicular or orthogonal to the axis of the shock absorber itself.
Claims8
Hydraulic shock absorber with a variable volume compensator for a vehicle, comprising:
- a cylinder sealed at one end for connection to a first part of the vehicle, said cylinder including first and second pressure chambers;
- a stem for attachment to a second part of the vehicle including a piston slidably engaged within said cylinder between said first and second pressure chambers
- means for connecting the second pressure chamber with the variable volume compensator for absorbing and releasing the liquid excesses which cannot flow from the second chamber to the first chamber, characterized in that the compensator is separate from the cylinder and reciprocally connected thereto with the possibility of cylindrical articulation such that the compensator can turn around an axis of the cylinder and can be blocked in a desired angular position, and such that the compensator itself can turn around an axis of an extension forming a part of said connecting means connecting the cylinder to the compensator;
- said connecting means including a first and second plurality of ring-shaped recesses, at least one of said first and second recesses having at least one opening forming a duct system that connects the compensator to the second pressure chamber, and sealing means being provided in at least one pair of said first and second recesses to avoid any liquid leakage from the said duct system.

A hydraulic shock absorber for a vehicle, comprising:
- a cylinder sealed at one end for connection to a first part of the vehicle, said cylinder including first and second pressure chambers each filled with a liquid;
- a stem for attachment to a second part of the vehicle including a piston slidably engaged within said cylinder;
- a variable volume compensator for absorbing and releasing any excess liquid flowing from the second chamber;
- means for connecting said variable volume compensator to the cylinder, said connecting means keeping the compensator separate from the cylinder and allowing for rotation about or articulation relative to a central axis thereof, as well as rotation around an extension forming a part of the connecting means;
- said connecting means further including a plurality of ring-shaped recesses, at least one of said recesses having an opening for allowing liquid to pass from the compensator to the cylinder and the remaining recesses each carrying sealing means to prevent any liquid from leaking therefrom.
