<p>A crank mechanism for an internal combustion engine comprises a cylinder (1), a piston (2) reciprocable within the cylinder, and a rotatable shaft (4). The piston (2) is in drivable connection with the shaft (4) via a connecting rod (3), a slipper (5) and a torque lobe (6). The connecting rod (3) is pivotally fixed to the piston (2), and the slipper (5) is pivotally attached to the free end of the connecting rod (3). The torque lobe (6) is a circular plate eccentrically mounted on the shaft (4) for rotation therewith about the axis thereof. The slipper (5) is slidable along, but restrained to, the rim of the torque lobe (6). The slipper (5) is constrained to move around a closed path, whereby rectalinear movement of the piston (2) is converted to rotary movement of the torque lobe (6) or vice versa.</p> |
