A self-closing valve arrangement includes a valve housing (1) having an inlet (2) and an outlet (3). Arranged therebetween is a valve (11, 17) which has an inlet (12) and an outlet opening (13) in connection with the outlet. A movable valve body (17) is coupled to a valve operating mechanism (21), which is guided by a lever (26). Arranged downstream of the outlet opening (13) is a passage or line (35-38) which connects the outlet (4) with a cylinder (39), and arranged in the cylinder is a movable thrust body (40) which co-acts with a piston rod (42) to activate the lever, and therewith the valve operating mechanism, to reset the valve to its closing position. |
