A SUCTION CUP DEVICE

摘要

The present invention relates to a suction cup device (7) in- tended to be attached to a wall surface (35) in a liquid filled space (1 ). The suction cup device (7) comprises at least a suc¬ tion cup (18), which comprises a cup-shaped recess (21 ) and a front surface (22) which defines an opening to the cup-shaped space (21 ), and a vacuum source (28), which is adapted to pro- vide a negative pressure in the cup-shaped recess (21 ) of the suction cup for attaching the suction cup (18) to the wall surface (35). The suction cup device (7) comprises force-generating means (12, 32) adapted to enable a flow of a medium out from the suction cup device (7) in such a direction in the liquid filled space (1 ) such that a reaction force is created which pushes the suction cup (18) against the wall surface (35).
