Lock cylinder with plate tumblers for a cylinder lock, as well as a cylinder lock having a lock cylinder of this type

A lock cylinder for a cylinder lock, in particular for motor vehicles for construction and agriculture machines, comprising:

• a cylinder axis as well as a longitudinal central plane containing the cylinder axis and a transverse central plane perpendicular thereto, likewise containing the cylinder axis,
• a cylinder housing having an axial core receiving cut-out and at least two axially extending blocking grooves that are open to the core receiving cut-out,
• a cylinder core supported inside the core receiving cut-out, having an axial key channel and a plurality of guide slots extending through the cylinder core in a plate-sliding direction perpendicular to the transverse central plane,
• a plurality of strip-shaped plate tumblers, the plate tumblers each having a guide and blocking strip, a single control and counter bearing lug protruding from the guide and blocking strip toward the longitudinal central plane and located adjacent one end of the guide and blocking strip, the plate tumblers being supported in one of the guide slots such that they can be displaced back and forth in the plate sliding direction, wherein the plate tumblers each have a locking position, in which they each engage with one of the blocking grooves such that the cylinder core is connected to the cylinder housing in a non-rotating manner about the cylinder axis, and having a non-locking position, in which they are driven into the cylinder core far enough that they do not engage in the blocking grooves and the cylinder core can rotate about the cylinder axis in the cylinder housing,
• a plurality of spring clamps biasing the plate tumblers in a plate blocking direction and into their locking position,
• wherein, in each case, two of the plate tumblers are connected to a single spring clamp of the plurality of spring clamps and biased in opposite directions into their respective locking positions and are disposed adjacent to one another in the axial direction in the same guide slot, the two plate tumblers disposed in the same guide slot lie with plate surfaces against one another such that they can slide.
