Trimming device for e.g. autonomous underwater vehicle, in oil and gas industry, has bellow trimming unit with two bellows, where bellows are formed from wall made of flexible material for changing volumes of bellows

摘要

The device has a bellow trimming unit with two bellows (101, 102) that are connected by a fluid connection. A trimming fluid is exchanged between the bellows by the fluid connection, and has density different than that of water. The bellows are formed from a wall made of flexible material for changing volumes of the bellows, where the wall has a section that is guided using a bellow guide. The trimming unit has a conveying device for conveying the fluid between the bellows over the fluid connection.
