Zusammenfassung:	The solution applies to the double non-return valve with the logical function "or" for the regulation of the flow direction. The goal of the solution is to simplify the mount of the valve, to reduce the flow losses, weight and dimensions. The merits of the solution concerns the fact that a guiding gasket of the controller with radial holes is placed among the seal seats. The holes lead into a recess that is made on the outer surface of the guiding gasket. The radial output holes are arranged against the recess of the guiding gasket and are created on the surface of the extension of one of the closure members. A space, placed against the radial output holes all over the surface, is created between the inner face of the first closure member and the shoulder of the second closure member. The space is connected to the third passage hole in the valve casing.
