    • A master cylinder for the clutch or brake of a motor vehicle has a housing for a reciprocable piston one end of which receives the spherical head of a reciprocable piston rod. The head is held in a desired position relative to the piston by a one-piece or composite coupling device having a first section exerting a pull or bearing upon the head of the piston rod and a second section which is confined in or surrounds the end of the piston and urges the first section in a direction to hold the piston rod against axial movements relative to the piston. The coupling device and/or the piston are or can be made of a plastic material, and the connection between such parts is or can be established by snap action.

    • An electromagnetic drive mechanism (1) for the periodic movement of at least one valve (2) for gas exchange of an internal combustion engine is provided. The valve (2) includes a disc-type rotor (9) located at an end (8) of its shaft (5). The rotor (9) is surrounded by a stator (12), a small gap (22) located between the rotor and the stator. The rotor (9) and stator (12) have ring windings (10, 13). When the stator (12) is supplies with electric voltage from a voltage converter (13a) with a microprocessor (14), the rotor (9) with the valve (2) is moved axially by the magnetic field which forms. The drive mechanism (1) operates selectively as a synchronous motor, reluctance motor, or asynchronous motor, and is provided with mechanisms (21) for current regeneration so that after the electric drive mechanism (1) is turned off immediately before reaching an excursion limit of the valve (2), the electric power gained in this way can be stored intermediately and supplied for the next lifting travel to the drive mechanism (1).
    • 提供了用于内燃机的气体交换的至少一个阀(2)的周期性运动的电磁驱动机构(1)。 阀(2)包括位于其轴(5)的端部(8)处的盘形转子(9)。 转子(9)由定子(12),位于转子和定子之间的小间隙(22)包围。 转子(9)和定子(12)具有环形绕组(10,13)。 当定子(12)从具有微处理器(14)的电压转换器(13a)供应电压时,具有阀(2)的转子(9)由形成的磁场轴向移动。 驱动机构(1)选择性地作为同步电动机,磁阻电动机或异步电动机工作,并且设置有用于当前再生的机构(21),使得在电动驱动机构(1)在达到偏移极限之前立即关闭 (2)中,以这种方式获得的电力可以被中间存储并提供给下一个提升行程到驱动机构(1)。

    • In a belt or chain tensioner a sliding bearing ring is arranged between an element rigidly connected to the housing and an element rigidly connected to the tension arm. In order to achieve an improved damping, the sliding bearing ring is provided at one place with a through-slot into which engages a projection on one of the two elements. In addition, the sliding bearing ring is preferably provided with at least two, and preferably more, axially oriented grooves which define narrow and flexible lamellae formed between them. The lamellae are inclined with respect to and bear against a facing peripheral surface of one of the two elements in order to obtain a direction-dependent damping, since the lamellae are easily pushed aside in one direction of rotation but are entrained and pushed up into an upright position in the opposite direction of rotation.
    • 在带或链条张紧器中,滑动轴承环布置在刚性地连接到壳体的元件和刚性地连接到张力臂的元件之间。 为了实现改进的阻尼,滑动轴承环在一个位置处设置有通孔,其中两个元件之一上的突起接合在该通孔中。 此外,滑动轴承环优选地设置有至少两个,优选地更多的轴向定向的凹槽,其限定在它们之间形成的窄且柔性的薄片。 薄片相对于两个元件之一的相对的外周表面倾斜并且抵靠在两个元件中的一个元件的相对的周向表面上,以便获得方向依赖的阻尼,因为薄片容易地沿一个旋转方向被推开,但被夹带并被推入 直立位置在相反的旋转方向。
