    Patent number: 6029541
    Abstract: In a reciprocating machine having piston/cylinder units arranged in line, a cam member having diametrically opposed cams is fixed to a crankshaft with the cam member arranged in a central transverse plane. A balancing mass is in contact with the cam member by way of a cam roller. The cam roller is maintained in permanent contact with the cam member by a compression spring which is seated against the machine. The cams are identical and neutralize second order free inertial forces.
