Abstract
Central guide means for the piston rod of apparatus provided with a piston reciprocating in a cylinder and comprising a piston rod centrally journaled proximate its free end between two journaling points of a guide lever, the guide lever being essentially oriented in the axial direction of the cylinder and being journaled at two journaling points on a pair of connecting rods of equal length. Fixed pivoting shafts are disposed parallel to each other and spaced equidistantly on opposite sides of a longitudinal axis of the cylinder, the pivoting shafts being coupled to the connecting rods and separated relative to the longitudinal axis of the cylinder by a distance corresponding to the distance between the journaling points of the guide lever.

In a piston machine having a cylinder with a longitudinal central axis, a piston rod reciprocating within said cylinder and having a free end, and a driving rod, central guide means comprising a journaling point along said longitudinal axis, a guide lever coupled at its center to said free end of said piston rod and to said driving connecting rod at said journaling point, said lever being approximately oriented along said longitudinal central axis, a pair of connecting links of equal length, said lever being journaled at two lever journaling points equidistantly spaced on opposite ends of said lever to said connecting links, means fixing the free end of each of said connecting links to one of a pair of fixed points equidistantly spaced and on opposite sides of said longitudinal central axis, said fixed points being separated in the longitudinal axial direction of said cylinder by a distance equal to the distance between said lever journaling points.
