    • The invention relates to a cylinder lock with a cylinder housing (1) and, rotatably mounted therein, a cylinder plug (2) comprising a key passage extending in its axial direction, with a lock bit (5) coupled to the cylinder plug and rotatably mounted in the cylinder housing (1), there being provided in the cylinder housing and in the cylinder plug a plurality of mutually aligned bores which extend into the passage and in which there are, by a spring force in the direction of the passage, plug pins which are of different lengths and housing pins which are preferably of the same length, there being formed between the cylinder housing and the cylinder plug a first separating joint traversed by the housing pins when the key is not inserted into the lock, the ends of the plug pins so co-operating with the locking notches of the key that when the key is inserted the pins are displaced in their axial direction into a position in which the bearing ends of all plug and housing pins are located in the first separating joint and so allow a rotation of the cylinder plug and of the lock bit. The invention envisages disposing in the cylinder housing (1) a displaceable barrier element (9) which locks the lock bit (5) as soon as the cylinder plug (2) is removed from the cylinder housing (1). This ensures that even if the cylinder plug is removed from the cylinder housing by force, which results in a shearing of the plug pins, the lock bit cannot be rotated.
    • 本发明涉及一种具有气缸壳体(1)并且可旋转地安装在其中的气缸塞(2),其包括沿其轴向方向延伸的键通道,锁定位(5)联接到气缸塞并且可旋转 安装在气缸壳体(1)中,在气缸壳体和气缸塞中设置有多个相互对准的孔,其延伸到通道中,并且通过沿通道的方向的弹簧力将塞子 具有不同长度的销和壳体销优选地具有相同的长度,在气缸壳体和气缸塞之间形成有当钥匙未插入锁中时由壳体销横穿的第一分离接头, 所述插头销与所述键的锁定凹口配合,当所述键被插入时,所述销在其轴向方向上移位到所有插头和壳体销的轴承端所在的位置 在第一分离接头中,因此允许气缸塞和锁定位的旋转。 本发明设想在气缸壳体(1)中设置可移动的阻挡元件(9),一旦汽缸塞(2)从气缸壳体(1)移除,其就锁定锁定位(5)。 这确保即使气缸塞通过力从气缸壳体移除,这导致插头销的剪切,锁定位不能旋转。
