<p>The valve has a check valve with a band (9) formed of a closed ring (7), which is supported on an inner side of a central guide in a freely rotating manner. The ring is an opening-free band, which closes passage openings to the guide during drop of the setback pressure. The ring is made up of a spring steel, where the steel forms the ring by an overlap (31) of a section of the bands at about 180 degree. The passage openings are asymmetrically distributed on a section of the central guide.</p> |
