<p>The machine, for example an internal combustion engine or pump, has at least one cylinder 4 housing two opposed pistons 5 adapted to reciprocate in opposite directions and define a common working chamber 13. A main shaft 1 carries two contoured tracks 3 each having opposed, axially facing, endless, substantially sinusoidal cam surfaces 3 sec . Bearings 8 and 9 mounted on connecting rods 6 abut the cam surfaces 3 sec so that reciprocation of the pistons 5 imparts rotary motion to main shaft 1, or vice versa.</p> |
