    • The invention relates to a piston (4) for a positioning device that can be operated by means of fluid, which piston has a one-piece piston body (16), in which an annular accommodating groove (25) is formed, which is coaxial to the longitudinal axis (5) of the piston (4) and which has two lateral groove flanks (33a, 33b) that face each other. A permanent magnet assembly (24) is arranged in the accommodating groove (25). The permanent magnet assembly consists of an elastic permanently magnetic magnet strip (35), which is bent into a ring structure and which has two strip end segments (35a, 35b) that face each other. The magnet strip (35) has a smaller width than the accommodating groove (25), wherein each of the two strip end segments (35a, 35b) of the magnet strip is firmly clamped in the accommodating groove (25). At least one clamping protrusion (46a, 47a; 46b, 47b) protruding from one of the groove flanks (33a, 33b) is responsible for the clamping.
    • 本发明涉及一种用于可借助流体操作的定位装置的活塞(4),该活塞具有单件式活塞体(16),其中形成有环形容纳槽(25),该环形容纳槽 到活塞(4)的纵向轴线(5)并且具有彼此面对的两个侧向凹槽侧面(33a,33b)。 永磁体组件(24)布置在容纳槽(25)中。 永磁体组件由弹性的永磁磁体条(35)组成,该磁体条(35)弯曲成环形结构并且具有彼此面对的两个条端部分(35a,35b)。 磁条(35)的宽度小于容纳槽(25)的宽度,其中磁条的两个条端部分(35a,35b)中的每一个被牢固地夹持在容纳槽(25)中。 至少一个从凹槽侧面(33a,33b)之一突出的夹紧突起(46a,47a; 46b,47b)负责夹紧。

    • The invention relates to a piston (4) for a control device that can be operated by means of fluid, which piston has a piston body (16), which has, in the region of the radial outer perimeter of the piston body, an annular holding recess (23) coaxial to the longitudinal axis (5) of the piston (4). The holding recess (23) has two lateral recess flanks (28a, 28b), which face each other and each of which has an undercut profile when viewed in cross-section, wherein each recess flank has an annular holding protrusion (38a, 38b) at a radial distance from the recess base (27). A guide band (22) having an annular structure sits in the holding recess (23). The guide band is held in that the holding protrusions (38a, 38b) interlockingly engage with the lateral edges (37a, 37b) of the guide band.
    • 用于控制装置的活塞(4)技术领域本发明涉及一种用于控制装置的活塞(4),该控制装置能够通过流体操作,该活塞具有活塞体(16),该活塞体在活塞体的径向外周的区域内具有环形 保持与活塞(4)的纵向轴线(5)同轴的凹部(23)。 所述保持凹部(23)具有两个彼此面对的侧凹部侧面(28a,28b),并且每个侧面在横截面上具有底切轮廓,其中每个凹部侧面具有环形保持突起(38a,38b) 在离开凹座(27)的径向距离处。 具有环形结构的导向带(22)位于保持凹槽(23)中。 导向带被保持为:保持凸起(38a,38b)与导向带的侧向边缘(37a,37b)互锁地接合。
