Abstract:
A locking device in combination with a lock cylinder, said lock cylinder including a rotor (1) and a stator (6), said combination comprising:at least one electronically controlled inhibiting element (2) movable to mutually lock said rotor and said stator, said inhibiting element being movable between a locking position in which said rotor is immovably locked relative to said stator and a free position in which said inhibiting element has no inhibiting effect on said rotor and stator; drive means for exerting a working force (FA) on said at least one electronically controlled inhibiting element to reversibly move said at least one electronically controlled inhibiting element between said locking position and said free position; wherein, guidance means connected to said drive means (9) clearly determine the position of said at least one electronically controlled inhibiting element (2) at least when said electronically controlled inhibiting element is outside said free position; restoring means connected to a support (31) immovable relative to said stator and connected via force transfer means (4) to said at least one electronically controlled inhibiting element for exerting a restoring force urging said at least one electronically controlled inhibiting element away from said free position when said at least one electronically controlled inhibiting element is near said free position but is inhibiting movement of said rotor relative to said stators wherein said at least one electronically controlled inhibiting element is movable to a rest position (xO) in which said restoring means exerts no force onto said inhibiting element and in which said at least one electronically controlled inhibiting element inhibits movement of said rotor relative to said stator; and, wherein said restoring means exerts a restoring force on said at least one electronically controlled inhibiting element directed away from said free position when said at least one electronically controlled inhibiting element is between said free position and said rest position, said at least one electronically controlled inhibiting element inhibits movement of said rotor in said rest position and in positions between said rest position and said free position.
