ABSTRACT:
This invention relates to a device comprising a sealing valve carried by a control arm inside a vessel and cooperating with a seat around an opening. The mechanism for operating the valve comprises a hollow rotary support housed about its axis of rotation X in a leaktight bearing on the wall of the vessel and connected to the other end of the control arm by means of a device permitting axial displacement of the valve in relation to its seat. In order to reduce the space required for the movements of the valve, the support of the valve operating mechanism is mounted in such a manner that its axis of rotation X forms an acute angle with the vertical axis of the opening of the vessel.
