| 摘要 |
<p>The invention concerns a device (1) comprising two components (2, 3) connected to each other with possible displacement of one component relative to the other, sealing means (4) arranged between said two components (2, 3), and flow rate adjusting means (23, 56) actuated by displacement of one component (2, 3) relative to the other. The invention is characterized in that the device (1) comprises positioning means (15, 35a to 35d, 36a to 36c) for placing the two components (2, 3) in two different positions, namely a first so-called sterilizing position, wherein said two components (2, 3) do not, or hardly exert, any stresses on the sealing means (4), and second so-called operating position, wherein said two components (2, 3) stress the sealing means (4) to provide the required sealing conditions.</p> |
