ABSTRACT:
A reciprocating-piston machine includes a cylinder; a piston received in the cylinder for reciprocating motion therein; a crankshaft having a crankshaft axis and being torque-transmittingly connected to the piston; a control disk mounted on the crankshaft for rotation therewith in a plane of rotation; an elongated weight-compensating member having opposite ends and extending transversely to the crankshaft axis; a follower roller carried by the weight-compensating member and riding on a cam track of the control disk; a supporting arrangement supporting the weight-compensating member at its ends substantially coplanar with the plane of rotation of the control disk for guiding the weight-compensating member in displacements towards and away from said crankshaft; a spring arrangement included in the support arrangement for urging the weight-compensating member toward the crankshaft to press the follower roller against the cam track with a spring force; and an adjusting device for varying the spring force.
