Abstract
A flat seat valve for the control of flowing media is described, which valve comprises a control membrane, clamped in fixedly in the valve housing as a movable valve member which is actuated by a solenoid and an armature; the membrane, which is mounted between two valve seats, serves as the movable member controlling the flow of the medium past the two valve seats and is so arranged that a change in one sense of the cross-sectional flow area at one of the valve seats leads to a change in the cross-sectional area of flow in the opposite sense at the other valve seat; the valve serves particularly for the control of the flow of liquids which serve as control media for fuel metering devices.
