Abstract (en)
[origin: EP1447499A2] Lock cylinder, especially a double lock cylinder (1), comprises a lock element (27) arranged coaxially between two cylinder cores (9, 10), and a coupling (14) consisting of two coupling elements (16, 17), each having a spring element (18, 19) for rotating connection of the cylinder cores and lock element. A pressure spring (15) arranged between the two coupling elements has a lower spring force than the spring force of the spring elements. Independent claims are also included for alternative lock cylinders. Preferred Features: When no key is inserted, the coupling elements are arranged a distance apart by the pressure spring so that the lock element can freely rotate.
