A piston, (1) incorporates a pair of tear-drop shaped springs (6) acting, in use, between the crown (2) of the piston and an associated connecting rod (4) so as to bias the connecting rod away from the piston crown (2). The springs (6) are supported by support members (7 and 8), the springs 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 to the connecting rod (4) in such a manner that the springs (6) permit the carrier (5) to move axially relative to the piston crown (2). The springs (6) are made of a beta titanium alloy such as gum metal. |
