<p>The valve has a valve housing (20) inserted into an opening (11) of a fluid container. A lower spring (9) is pre-stressed between a valve piston (30) and a stopper (50). An upper spring (8) is pre-stressed between the valve piston and a shaft body (40). A volume is formed between the shaft body and an upper closure i.e. insertion part (22), of a valve housing (20). Partial volumes (2, 3) are combined with the volume via an inlet channel (42) of the shaft body by actuation of the valve. An outlet channel (44) of a shaft (41) is connected with the volume by further actuation of the valve.</p> |
