- a radial bore wherein a steel ball is placed to stabilize the outer core rotation, as the diameter of the ball is bigger than the width of the additional slot.
- an anti-drilling protection is also realized in case of overcoming the anti-breaking protection, as next to the slot formed in the housing and next to the additional slot formed in the outer core there are mounted additional inserts of a hardened metal in relevant coaxial formed bores in the housing and in the outer core, which are chess-disposed to the basic housing and to the basic core bores.
- additional core bores wherein additional core pins are disposed, and inside the housing there are formed longitudinal channels with a configuration corresponding to the additional core pins configuration.
- the cylinder lock consists of a housing, a cam, in the front part of the housing there is a slot, as an inner and an outer cylinder core are fixed by rings thereto, said cores have a key channel for the key insertion.
- the outer and the inner core have different lengths.
- coaxial basic bores wherein closing pins, springs, housing and core pins are disposed.
- additional slots arranged in the same plane respectively with the slot formed in the front part of the housing and with the second slot formed in the back part of the housing, so that two common slots form respectively in the front and in the back part of the housing providing a weaken cross section wherein plastic holders are mounted closing the common slots so therein springs, housing and core pins are disposed.
