Abstract
A lock device comprises a housing (2) which includes an opening (4) and a core (10) which is rotatably disposed in the opening and which includes a key way (12) for reception of a key. A latching element (20) co-acts between the housing (2) and the core (10) and is movable between a release position in which the core is rotatable relative to the housing, and a latching position in which rotation of the core relative to the housing is blocked. An electronically controllable actuator (30) is disposed in the core and is rotatable between an opening-registering-position in which the latching element is movable to the release position, and a latching position in which movement of the latching element to said release position is blocked. A spring (46) abuts an abutment portion (30c) of the actuator. Since the spring is provided with two mutually parallel leg portions (46d, 46e), which abut radially opposite surfaces of the abutment portion of the actuator, several advantages are obtained. Firstly, the damping spring is easily assembled without any fixation in the core. Furthermore, the balancing ensures that a predetermined force is exerted on the neck portion, which increases the accura…
