ABSTRACT:
A diaphragm valve which may serve as an equal pressure valve or as a pressure equalizing valve of a fuel metering and distributing unit for an externally ignited internal combustion engine. The valve has a flexible diaphragm having a clamped diameter and to which a valve plate is connected. The valve plate operatively cooperates with a valve seat of the valve and has a diameter which is as large as possible in relation to the clamped diameter of the diaphragm. The valve also includes a stationary thrust plate which is concentrically disposed relative to the valve seat, which defines a knife-shaped edge which lies in a common plane with the valve seat and which operatively cooperates with the valve plate. The knife-shaped edge has a diameter which is as large as possible in relation to the diameter of the valve plate.
