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.
