| 摘要 |
The invention relates to an actuation device for a seal of those comprising a lower part rotating about a longitudinal axis between two positions, the first of which is a essentially vertical downward position and the second of which is an obliquely raised position, the device comprising elastic means acting on the lower part of the seal, tending to maintain it in the mentioned second obliquely raised position, as well as closing means suitable for exerting a force opposite to the action of the elastic means and for forcing the lower part of the seal to adopt the first, essentially vertical, position only when the door incorporating the seal is in its closed position. |
