Lubricant is fed, via ducts 25, to the slidable bearing unit 20 and the seating of the ball-end 12 therein. Alternative sliding bearing units 20 for mounting the ballend 19 of the arm 18 in plain (22) or ball races (30, 32) are illustrated in Figs. 3 to 6 (not shown). The mechanism can be used in a twin-cylinder two or four stroke cycle I.C. engine having the common piston 12 driving through the flywheel 14 to an output shaft 15, which arrangement could alternatively form a pump or compressor with the shaft 15 forming the input.
