A hinge (1) for a door opening over a horizontal axis, of the type comprising first and second supports (2, 3) that can be fixed to a compartment structure and to a door, at least rotatably constrained to each other through a pin (10). The hinge (1) comprises a fluidic cylinder-piston damper (9) of the type with internal flow leakage of the fluid contained therein. The damper (9) has a piston (18, 19) with a through-hole (20). The piston (18, 19) can have an appendix (19) that non-sealingly engages a chamber (17) when the door is closed, to increase the dampening. The hinge (1) has elastic means (7) such as a spring, to counteract the falling movement of the door when it is opened. The hinge (1) can be of the cam type, with a cam (4) and an abutment (5).

1. A hinge for a door at least partially covering a compartment, comprising: first and second supports that are fixed to a compartment structure and to a door, respectively, said first and second supports being at least rotatably constrained to each other;an elastic means counteracting a movement of said first support relative to said second support;at least one cylinder-piston fluidic damper comprising a piston configured to be constrained to said first support or said compartment structure, and a cylinder configured to be constrained to said second support or said door;wherein said at least one damper allows internal flow leakage of the fluid contained therein, said cylinder comprising a chamber of reduced section placed at one end thereof and defining a higher-resistance region, wherein a higher resistance is offered against relative movement, at least in one direction, of said piston, relative to other inner regions of said cylinder and said piston;said piston comprising a cylindrical body, sliding within said cylinder, and having, on a first side of a base thereof, at least one cylindrical appendix of reduced section, which is configured to be non-sealingly engaged within said chamber of reduced section of the cylinder, and said piston is sealingly sliding within said cylinder and comprises a through hole for internal flow leakage of said fluid having an inlet port located on a side wall of said cylindrical reduced-section appendix and an outlet port formed on a second side of the base of said cylindrical body opposite to the first side of the base from which said appendix projects. 2. The hinge according to claim 1, wherein it comprises movement guide means having at least one moving arm being engaged with a respective abutment, which are functionally connected to said first and second supports, respectively, and at least one moving element connected to said movement guide means, which is moving relative to said second support during the movement of said door, said at least one moving element being constrained to a rod of said piston of said at least one fluidic cylinder- piston damper, and said cylinder being fixed to said second support. 3. The hinge according to claim 1, wherein in said higher-resistance region of the at least one damper, said cylinder and said piston are configured to define a variation of fluid flow section at least in one direction of travel of said piston. 4. The hinge according to claim 2, wherein said inner higher-resistance region is located at an end of said cylinder towards which said piston moves when said at least one moving element moves relative to said second support during a movement of said door to at least partially close said compartment. 5. The hinge according to claim 2, wherein between said at least one moving element and said second support said elastic means are interposed which counteract a sliding movement, at least in one direction, of said at least one moving element. 6. The hinge according to claim 2, wherein said elastic means counteract a sliding movement of said at least one moving element relative to said second support at least while said door is moving to at least partially open said compartment. 7. The hinge according to claim 2, wherein said at least one moving element coincides with an end of said at least one moving arm with which said movement guide means are provided. 8. The hinge according to claim 2, wherein said at least one moving element is constrained to said at least one moving arm with which said movement guide means are provided. 9. The hinge according to claim 2, wherein said at least one moving arm of said movement guide means comprises at least one portion acting as a cam and said respective abutment comprises at least one follower for said portion acting as a cam. 10. An oven door comprising the hinge of claim 1. 11. A cabinet door comprising the hinge of claim 1.
