Double lock cylinder, has spacer ring attached to diameter-reduced head section and laid at passage and at stop stage with free point of head section rising into key channel

摘要

The lock cylinder has a core borehole including an internal section with a decreased cross-section under formation of a stop stage. Core pins (6, 16) are comprised of a block section (8) mounted in an outer section of the core borehole, and a diameter-reduced head section (7) is projected into a key channel through the internal section and formed under formation of a passage at the block section. A spacer ring (10) lying at the passage is attached to the head section and laid at the stop stage with a free point (7') of the head section rising into the key channel.
