    摘要: A check valve arrangement utilizes a disc (15) for a valve member while eliminating the need for a ball. A valve seat in the common sense is unnecessary, too. Instead, a substantially flat surface (13) interacts with the disc (15). In order to allow unidirectional flow only, the disc (15) is biased toward the surface (13) by means of an elastic bias ring (17) which itself is held in place by a retainer (6) extending through the center hole (16) of the disc (15) and thereby axially guiding the disc (15). If desired, the flat surface (13) can be supplemented with an embedded sealing ring 18 to provide optimum sealing properties without precise machining of the surface (13). By designing the disc (15) and the retainer (6) in rotational symmetry, a directional adjustment of the parts is made unnecessary.
