摘要
The object of the invention is a device for automatic closure of the holes of passage of air in a cylinder, in particular for the support cylinders (10) of the sleeves and for the sleeves (22), which is characterized in that it comprises, inserted in the thickness of the wall of this cylinder, a support (32), a seat (34) with an internal passage (40) and a valve (36) which is movable in translation in the support and can assume two positions, the first in which the valve comes into leaktight contact with said seat and the other, in which it is recessed so as to leave a passage.
