1. A hinge for closing panels of the access opening of refrigerated cabinets, where said hinge comprises:
a casing that can be fixed to a fixed frame of the access opening, where said casing contains a mechanism configured to allow the rotation of said panel about an axis between a closed position and an open position of the access opening of the refrigerated cabinet,
an elastic return means to allow the return from the open position to the closed position of the panel; and
a braking element configured to interact with the aforesaid mechanism to brake the closing movement of the panel generated by said elastic return means, wherein the mechanism configured to allow the rotation of said panel about the axis comprises a crank configured to be placed in rotation by the opening and closing movement of said panel, said crank being kinematically connected to a connecting rod in turn connected to a piston,
wherein said elastic return means for the return from the open position to the closed position of the panel comprises a spring configured to act on the piston and assuming a maximum compression configuration, when the piston is at a maximum distance position with respect to the axis, and a maximum extension configuration, when the piston is at a minimum distance position with respect to the axis.
