A synchronizer balancer assembly includes a counterbalancing movable portion 62 and a coupling 63, 64 between the counterbalancing movable portion and the movable assembly for causing reciprocating movement of the counterbalancing movable portion 62 in a direction opposite to the direction of movement of the movable assembly and in synchronization therewith, the synchronizerbalancer coupling being disposed between the power piston and the connection 48. In a modification a control cylinder 55 is positioned adjacent the engine cylinder. The energy absorbing device 14 may be a pump, a generator, a power saw or a double acting compressor. The control cylinder may be dispensed with. Specification 210532 is referred to. |
