A piston (1) incorporates spring means (8) acting, in use, between the pisto n and an associated connecting rod (4) so as to bias the connecting rod away from the crown (2) of the piston. The spring means (8) is constituted by a pair of disc springs (9) whose circumferential edge portions are supported a nd separated by a substantially annular support member (10, 11), the spring mea ns being located substantially in the region of the piston crown (2). A carrier (5) is positioned within the piston (1), the carrier being slidably mounted within the piston for axial movement relative thereto, and being connected t o the connecting rod (4) in such a manner that the spring means (8) permits th e crown (2) to move axially relative to the carrier (5). |
