Definitions

  • the power is contemporaneously transmitted to two counter rotating crankshafts by two connecting rods and vice versa, eliminating the piston friction that is not possible to eliminate with the normal crank mechanism.
  • the piston pin and the piston run in their stroke along the geometrical axis of the cylinder and consequently it is possible to avoid the friction between the piston and the cylinder that characterize the normal crank mechanism.
  • piston skirt surface has to be very large to avoid excessive specific pressure values.
  • the Fig. 4 shows the piston (a), at the top dead centre, which start its cycle connected to the connecting rods (c, c 1 ) by the piston pin (g).
  • the piston (a) goes in its up stroke from the position in Fig.6, to the position of Fig.4, thanks to the energy transmitted by the counterbalance (k, k 1 ) which are joined with the cranks (d, d 1 ) and so it is possible to transmit their rotational motion to the connecting rods (c,c 1 ) which in their translation and rotation motion, drive the piston (a) connected by the piston pin (g), to the top dead centre, concluding the cycle.
  • the fork small end consents to the small ends of the respective connecting rods to be aligned on the same axis, to be joined by the same piston pin.
  • crank arm (d) and the crank arm (d 1 ), have respectively a clockwise rotation an a anticlockwise rotation.
  • crankshafts axes If required by the design of the engine or compressor, it is possible to change the distance between the crankshafts axes, and the crank radius/connecting rod ratio, without altering the principle of working.
