ABSTRACT:
A machine has two cylinders with respective pistons slidably supported therein, and has two crankshafts carrying counterweights operatively coupled to the respective pistons. A balance shaft carrying a balance weight is associated with and extends parallel to each crankshaft. The cylinders, crankshafts and balance shafts are parallel to and arranged in mirror-image fashion on opposite sides of a plane of symmetry. The crankshafts rotate synchronously in opposite directions, and each balance shaft rotates in an opposite direction from and at twice the speed of the associated crankshaft. In one embodiment the machine is an internal combustion engine and fuel is supplied to the cylinders through an eddy chamber which communicates with both cylinders through respective ducts. Two machines of the above type, an internal combustion engine and a compressor, can be operationally coupled, each crankshaft and balance shaft of the engine directly driving a respective crankshaft or balance shaft of the compressor.
