Abstract

The door closure device comprises a damping unit (12) with fluid passages (21,22) which only some allow fluid to pass in a direction corresp. to that of opening of the door panel (15), in order to limit resistance to the opening action. A closure mechanism (7) comprises a cylinder (9) and a piston (8), and a vacuum acting as a spring is formed in a chamber of the piston (8) when the door panel (15) is opened.
