    • The fluid dynamic bearing system has at least one stationary part, and at least one rotating part that is supported rotatable about a rotational axis with respect to the stationary part. A bearing gap filled with bearing fluid is formed between mutually opposing surfaces of the stationary and of the rotating part. The bearing system includes at least one fluid dynamic radial bearing and at least one fluid dynamic axial bearing that are disposed along sections of the bearing gap. In one aspect of the invention, an annular sealing gap for sealing open ends of the bearing gap has one end connected to the bearing gap and one end connected to an annular reservoir, the outside radius of the reservoir measured from the rotational axis being larger than the outside radius of the sealing gap.

A bearing gap filled with bearing fluid is formed between mutually opposing surfaces of the stationary and of the rotating part. The bearing system comprises at least one fluid dynamic radial bearing and at least one fluid dynamic axial bearing that are disposed along sections of the bearing gap. Moreover, sealing means for sealing the open ends of the bearing gap are provided. According to the invention, one of the sealing means comprises an annular sealing gap that has one end connected to the bearing gap and one end connected to an annular reservoir, the outside radius of the reservoir measured from the rotational axis being larger than the outside radius of the sealing gap.

    • The invention relates to an operating device for a rotatable closing element of a valve such that, a desired angle of rotation can easily be set and maintained. This is achieved in that two guide grooves (2f), which are incorporated diametrically opposite each other, are bounded on all sides by a piston shank (2b), in that their respective courses are precisely or more or less symmetrical at all points, in that in each instance the courses have, in relation to the axis of the piston (2), a greater pitch angle in a central portion (angle b) than in their two portions on the end side (angle a) (a>b), and in that the stroke of the piston (2) is limited on one side by application of the front-end piston shank (2b) to the cover element (4) and on the other side by application of a piston base (2a) to a stop element (9; 20; 20.1) which is mounted in the housing base (1b) of the housing (1)
    • 本发明涉及一种用于阀的可旋转关闭元件的操作装置,使得可以容易地设定和保持期望的旋转角度。 这是通过两个直径相对的导向槽(2f)通过活塞杆(2b)在所有侧面上限定的,因为它们各自的横列在所有点处精确地或更多或更少对称,在 在每种情况下,课程相对于活塞(2)的轴线具有在中心部分(角度b)上比在其端侧(角度a)(a> b)上的两个部分更大的俯仰角, 并且通过将前端活塞杆(2b)施加到盖元件(4)并且另一侧通过施加活塞底座(2a)而限制活塞(2)的冲程, 到安装在壳体(1)的壳体基部(1b)中的止动元件(9; 20; 20.1)
