Abstract: A ball and socket joint body for terminals of control cables has a transverse passage with respect to the coupling of the cable with the terminal which forms two reciprocally opposed inlet mouths of freely choosable alternative use, and a central chamber for housing a ball with elastically deformable retaining and seat structure. The retaining and seat structure can comprise a sleeve provided with perimetral projections, or a first shock-absorbing sleeve and a second sleeve provided with coplanar sectoral projections or two "U"-shaped springs or a sleeve and two "U" shaped springs which traverse it.

Abstract: The control cable self-adjusting device has an extended cylindrically shaped hollow base body (5) open at one of its ends (9) and a regulating stem (6) held inside the interior of the base body (5) by a retaining device. The closed end (10) of the base body (5) and the front end (15) of the regulating stem (6) are connected to respective intermediate ends (13,14) of the sheath (4) of a control cable (2). The retaining device (7) includes a saw-toothed threaded section (25) in the interior of the base body (5) and a retaining coil (26) connected to the stem (6) and engaged with the threaded section (25). The control cable length adjustment is made by pulling apart the intermediate ends (14,15) of the sheath (4) to deform the retaining coil (26) and move it from the inside to the outside of the base body (5) or by screwing the base body (5) on the stem (6) in either direction via the retaining coil (26).

Abstract: A check valve for pistons of hydraulic self-adjusting devices comprises a flow body (10) formed by a frustoconical portion linked at the smaller diameter end thereof with a cylindrical portion the free end of which is attached to the inner end of the rod of the device, and by a stopper body coaxial with said rod and which may freely slide on said cylindrical portion. The axial bore of the stopper body has at the end thereof facing the flow body a seal seat of progressively increasing size dimensioned to mate with the sealing gasket of the flow body. The configuration of the seal seat and of the sealing gasket cause progressive closing of the valve when the rod is pulled, which allows during closing the flow of fluid between both half-chambers of the main body.
