Abstract
An extraction valve for overpressurized gas flowing from a compressed gas reservoir is disclosed. The extraction valve has a valve seat carrier, including a conical valve seat emerging centrally into an outflow chamber. An extraction piston, which is mobile in its axial direction at least indirectly via an electromagnetic coil, includes a valve body cooperating with the valve seat. An inflow chamber for the pressurized gas is designed totally or partially on the circumference of a central axis of the extraction piston and is connected in the axial direction of the extraction piston against a flow direction of the gas when the extraction piston is in the open position, between the valve seat and the valve body via an intermediate connection with an intermediate volume which includes a connection with the region in which the valve seat and the valve body co-operate.
