摘要: A valve for dispensing a preferably viscous fluid is adapted in connection with the operation to open under action of positive pressure fluid, produced e.g. by means pump (1), and close itself when pressure, thus operation, has ceased. The (2) channel (9) an inlet outlet end (9a; 9b) axial direction flow (10). defined body portion (11) rigid material cover (12) flexible material. formed groove (13) substantially arcuate cross-section. edges extending (10) are sealingly connected (11). Towards (9b), conforms shape (13). prestressed engage wall certain engagement pressure.
