Abstract

A piston device comprising a piston 14, a part spherical projection 20 extending from the piston and a slipper 16 that includes a recess 24 to receive the projection, where a securing insert 40 comprises a part spherical surface to engage the projection and the piston is held captive within the slipper by securing the securing insert within the recess. The insert may be secured to the slipper by welding, press fitting or deformation of part of the slipper. Preferably the insert is comprised of hard tool steel and is of the same material as the projection. The device may also have a spacer 38 and a load element 34 to ensure correct location of the insert relative to the slipper.
