Abstract (en)
[origin: WO2019001725A1] Diving gear (1) comprising an air pump (2) having a rigid housing (3) with an interior space (4) and an opening (8) which is closed by a bag-like flexible part (11) in order to form a variable pump volume delimited by the housing (3) and the flexible part (11), wherein the air pump (2) is configured in such a manner that, in the event of a positive pressure caused by surrounding water (22), the flexible part (11) is pressed into the interior space (4), thus reducing the pump volume, and, at least in sections, lies against an inner wall (13) of the housing (3) in a contact portion (12) of the interior space (4), wherein the flexible part (11) can be pulled out of the interior space (4) counter to the positive pressure by muscle force of a diver (17), thus increasing the pump volume. According to the invention, an air duct (20) is provided which is configured in such a manner that, during the suction, the air can flow from the region (10) of an end (7) of the interior space in the direction of a start (6) of the interior space at least into a region (21) of maximum height (18), preferably into the region (9) of the start (6) of the interior space, and into the interior space (4).
