    摘要： The invention relates to a valve, especially a ball valve, comprising a base body (7) provided with a through-opening (8), a mobile valve body (3) for closing and freeing the through-opening (8), and an actuating mechanism which is used to displace the valve body (3) in order to free the through-opening (8). Said actuating mechanism comprises at least two wire-shaped elements (2) consisting of a shape memory alloy, said elements being fixed to the base body (7) or to a carrier body (1) connected thereto, and shortening alternately on each side when the temperature increases above a threshold temperature. Said elements are actively connected to the valve body (3) such that, if one element (2) is shortened on one side, the valve body can be displaced from a stable position on the through-opening (8) to a stable position close to the through-opening (3), and if the other element (2) is shortened on one side, the valve body can be moved back to the stable position on the through-opening (8). The actuating mechanism of the valve can be embodied in a compact manner and requires only a minimum amount of energy when in operation.

    摘要： The invention relates to an adjustable hydrocephalus valve, which can be locked in the respective selected valve position and unlocked for modifying the valve position. According to the invention, signals are provided for a treating physician in the event that an unlocking and another locking occur.

    摘要翻译： 一种可调节的脑积水阀，用于脑积水患者头颅脑脊液压力均衡。 阀门可调，以改变阀门的开启和关闭压力。 阀壳体具有可以被压下的盖部分，从而使锁定装置脱离以允许阀的调节。 盖部分向外凸出，但在压下时向内凸出。 当在向外凸起和向内凸起之间移动时，盖部分卡扣，从而产生指示盖部分已经从向外凸起切换到向内凸起的音频和/或视觉信号，反之亦然。

    摘要： The invention relates to an adjustable hydrocephalus valve comprising a mechanical brake. Said brake can be decoupled by pressing the valve housing percutaneously and allows in this state to adjust the opening characteristics of the valve by rotating externally disposed magnets. In order to detect the adjusted pressure or in order to adjust the pressure, specific adjustment or measuring pin principles are presented which simplify and at the same time improve the respective functions of measuring and adjusting.
