PCT No. PCT/GB91/00087 Sec. 371 Date Jul. 16, 1992 Sec. 102(e) Date Jul. 16, 1992 PCT Filed Jan. 21, 1991 PCT Pub. No. WO91/10848 PCT Pub. Date Jul. 25, 1991.A crank mechanism for an internal combustion engine comprises a cylinder, a piston reciprocalable within the cylinder, and a rotatable shaft. The piston is in drivable in connection with the shaft via a connecting rod, a slipper, and a torque lob. The connecting rod is pivotally fixed to the piston, and the slipper is pivotally attached to the free end of the connecting rod. The torque lob is a circular plate eccentrically mounted on the shaft for rotation therewith about the axis thereof. The slipper is slidable along but restrained to the rim of the torque lob. The slipper is constrained to move around a close path, whereby rectilinear movement of the piston is converted to rotary movement of the torque lob or vice versa.
