ABSTRACT:
A cylinder lock includes a rotor rotatably mounted in a bore of a stationary casing. A key passage in the rotor is blocked by a biased shutter which is caused to pivot against the action of a spring when a key is introduced into the key passage. The rotor includes a plurality of separated, spring-urged tumblers which engage with the key in the key passage. A soft-elastic wiper for removing water from the key is positioned in a lateral slot between the entrance of the key passage and a first tumbler. Flaps of the wiper form a normally closed slit which is openable by the force of the key when the key is advanced towards an operational position.
