<p>A mechanical regulator suitable for application on armchairs, easychairs, shutters and similar items, furniture generally speaking, consisting of a tubular casing (I4) with central area housing a sealed cell (I0) or a tubular body (5I) containing a viscous fluid like oil or grease, in which the end area (20) or ( 5) having a protruding annular body (2I) or gasket (54) of a coaxial item such as a central rod (I8) provided with several concave annular seats (I9) or external sleeve (29) or other similar members, is left free to slide. The inferior extremity of the aforesaid internal tubular casing (I4) is constrained or linked with a piston (I6) provided of a trunk-conic flare (I7) on its top, matching the trunk-conic flare of the lower end of a second piston (24) also coaxial with the above mentioned rod (I8), linked with the sliding sleeve (29). The superior piston (24) is provided of radial holes (26) housing some spheres (27), pushed inside the concave annular seats (I9) on the central rod (I8), when the trunk-conic flares (I7), (25) are matching together.</p> |
