A pressure drop hose valve comprises a valve body (1) having an inlet (4) and an outlet (5) as well as a throughflow passageway (6) which connects the inlet and the outlet and in which a valve cone (7) is axially movable. The portion of the valve cone (7) facing the outlet (5) is formed with a seat surface (10) for cooperation with a seat (9) provided in the passage of the valve body and normally located at a distance from said valve cone seat surface (10). A spring (13) strives to displace the valve cone (7) towards the inlet (4), the seat surface of the valve cone and the valve seat of the body being designed such that the valve cone, during its displacement towards the outlet (5) after activation of the valve following a pressure drop in the hose, is constantly held or wedged in the seat. |
