  • the introduction of force takes place at one ledge sliding edge 17a, 17b and the support takes place at the other ledge sliding edge 17a, 17b.
  • the platelet tumblers 5a, 5b supported in each case over their entire plate thickness d both in the cylinder housing 2 and in the cylinder core 4.
  • the strip-shaped plate tumblers 5a; 5b have no key receiving groove as the known platelet tumblers, the platelet tumblers 5a; 5b more stable. Because the key receiving groove causes a notch effect, which impairs the strength.
  • the strip-shaped platelet tumblers 5a; 5b is the second ledge sliding edge 17b from the first to the second ledge locking end 16a; 16b formed continuously or unnotched. And the first ingot sliding edge 17a is also formed from the control and abutment nose 19 to the second last locking end 16b through or unnotched.
  • leg springs 35 it was possible to reduce the diameter of the lock cylinder 1. Because the known, radially outwardly disposed compression springs occupy more space in the radial direction than the torsion springs 35 according to the invention.
  • the compression springs take more space in the axial direction, so that the axial length could be reduced in the lock cylinder 1 according to the invention.
  • the security against burglary is increased in the lock cylinder 1 according to the invention.

  • the abutment surfaces 33 and thus also the control and - abutment edges 20 of all platelet tumblers 5a; 5b thus all have the same distance from the transverse center plane 7. Respectively. they are arranged in the axial direction in alignment with each other. In the prior art, however is visible from the outside, that the control levels of the individual platinum tumblers are arranged in different positions.
  • the burglar resistance is also increased by the fact that the two platelet tumblers 5a; 5b are driven with the same leg spring 35 in opposite directions. For when attempted by means of a tool to move the one platelet 5a to its non-blocking position, the leg spring 35 is further tensioned and then the second plate tumbler 5b is pressed with increased force into its blocking position.
  • the platelet tumblers 5a, 5b are each arranged in a separate guide slot. According to the invention, two platelet tumblers 5a, 5b, which are axially adjacent to each other, are then driven in connection with the same leg spring 35.
  • the spring clip may also be a simple U-shaped spring clip, e.g. made of spring wire or sheet metal, act.
