Device for the sealed transfer between two enclosed volumes, comprising an external control lever

A sealed transfer device between two enclosed volumes, comprising

• a first and a second flange which define a passage opening into the enclosed volumes, it being possible for said first and said second flange to be secured to each other by a first bayonet connection, and
• a first and a second door which close off the passage openings, it being possible for said first and said second door to be secured to each other by a second bayonet connection,
• the first door being hingedly mounted on the first flange by means of a hinge, said hinge comprising a hinge pin and a plate that is fastened to the first door and secured to said hinge pin,
• characterized in that said device includes:
• an external manual control lever secured to a rotary pin which passes through the first flange and is coupled to the hinge pin in such a way that the actuation of the control lever drives the hinge pin, thus opening or closing the first door;
• a second rotational pin coupled by drive means to the rotary pin passing through the first flange and to the hinge pin, wherein the second rotational pin is offset with respect to the rotary pin.
