<p>The invention relates to a crank mechanism for enabling a crankpin to follow other than a circular path centred on the cranking axis. The mechanism comprises a crankshaft skeleton (10) defining at least one main bearing section (12) and one web (14) extending radially from the main bearing section (12). A housing (20) is mounted for sliding movement along the web (14) has a crankpin (32) secured thereto. Slidable guiding means (40, 46) are provided to cause the housing (20) to slide along the web (14) in synchronism with the rotation of the skeleton (10), such that the distance of the centre of the crankpin (32) from the centre of the main bearing section (12) varies as a function of the cranking angle.</p> |
