Abstract

The perforations in bush and plug are so arranged that, by rotating the plug in the bush, they can be brought into, or out of, line. The plug may be replaceable with a plug of different shape or with different placing of the perforations. The plug may be provided with a large number of small perforations. The size of the perforations may vary along the periphery of the plug. The plug may be provided with resistance means in the form of a perforated partition positioned inside the hollow space of the plug. The perforations in the plug wall and/or partition may be provided with friction increasing means, e.g. screw thread.
