The invention relates to a valve to be placed on a container, especially on a bottle in which pressure has built up. Said valve comprises a valve housing (1) in which at least one valve seat (23, 24) is provided. A valve seat (23, 24) which is independent of the pressure inside the bottle is located between a plunger (28) and the content of the bottle in a manner so as to be linked with the plunger (28). An accumulator (39) whose force can be varied presses against the other end of the plunger (28). The plunger (28) slides in a cylinder compartment (27) in the valve housing (1), said compartment being closed by a spring housing (34) that comprises an axial stepped bore (35) in which particularly the accumulator (39) whose force can be varied is received. Said accumulator (39) encircles an intermediate piece (36) as the helical spring and is supported on a head (37) of the intermediate piece (36) and on the plunger (28). A plunger compartment (26) upstream of the plunger (28) communicates with an outlet via a bore (42) in the intermediate piece (36), said outlet (51) being provided with a check valve (43). |
