<p>A valve device comprises an elastic sleeve (1), the interior of which constitutes a part of a liquid passage through the valve device, an annular seating surrounding the liquid passage, a sealing member (6), which abuts sealingly against the annular seating, so that the liquid passage is closed, and an operating member (7), which is rigidly connected to the sealing member (6) and which extends from the latter into the elastic sleeve (1). At bending of the elastic sleeve (1) the operating member (7) is adapted to be affected by the sleeve (1), such that the sealing member (6) is tilted against the annular seating and the liquid passage is opened. The annular seating is formed by one of the ends of the elastic sleeve (1).</p> |
