Abstract
A hinge for doors of appliances includes a movable arm connected to a door of the appliance, pivoted on a frame to rotate about an axis to make the door movable relative to the frame between closed and open positions. A control shaft extends longitudinally parallel to the axis and is connected to the frame. A sleeve attached to the movable arm extends parallel to the axis. An elastic element is contained inside the sleeve to generate an elastic force for closing the door. A mechanism drives the elastic element to determine the deformation and transmit to the movable arm the closing force. The mechanism includes two cylindrical cam operating units housed inside the sleeve, having first and second cylindrical cams operatively facing one another such that rotation of one about the axis determines translation of the other along the same axis and vice versa,
