摘要： The object of the present invention is hence an electro-actuator (1) for gas cooktops or the like, piloted by actuating means, comprising at least one safety electromagnet (4) forming part of a pilotstat, at least one cut-off means (2) of the fuel gas, substantially a sleeve provided with an outlet channel (22) and a conduit (23) of the fuel gas, of at least one safety shutter (20) whereon a pushing/pulling force (FF) acts that operates the safety closing of said outlet channel (22), at least a service shutter (20), and a support structure (10) provided with a cavity (100) within which a stem (21) is placed sliding, whereto at least one ferromagnetic element (32) cooperating with said safety electromagnet (4) and said shutter (20) cooperating with the cut-off means (2) of the fuel gas are constrained, where said safety shutter (20) and said service shutter (20) coincide in a same shutter (20); said ferromagnetic element (32) being anchored to said safety electromagnet (4) through an anchoring force (FP) of mutual attraction that arises when said safety electromagnet (4) is electrically powered, in particular through the flame sensor of pilotstat,characterised in that: said pressing/pulling force (FF) is of magnetic nature and susceptible to be won by the command forces (FS) exerted for the opening of said outlet channel (22) and by said anchoring force (FP).

摘要： The object of the present invention is an atmospheric gas burner (300) for cooking tops (400), in particular household cooking tops (400), where the air-gas mixture is obtained by the effect of the gas supply pressure using the principle of the tube ejector (10; 310) of Venturi that has a sufficient quantity Z≥1 of ejectors (310) to supply, globally, the maximum power (Wb) provided for the same burner (300).
Each of said ejectors (310) develops on a horizontal plane, has the axis of its diffuser (315) which in the first stretch (322) is substantially rectilinear and tangential to a circle with centre on the central axis (324) of said burner (300) while in the second stretch (323) gradually bends substantially as a spiral towards the same central axis (324), leads, downstream of said diffuser (315), to a converging channel (327) which gradually bends vertically upwards and which, in turn, leads to one or more diffusion chambers (328) to which one or more flame spreading caps (318) act as a cover.-

摘要： The object of the present invention is a ventilated hob (400) comprising a motor-driven fan (V) adapted to provide high pressure air to two or more burners (BRNi) thereof, each of said two or more burners (BRNi) at least comprising means (VG, 211; 211.a, 211.b) for supplying and regulating the flow of fuel gas (QGAS) in input into each of said two or more burners (BRNi), means (VP; 101; UG) for supplying the flow of combustion air (QAIR) in input into each of said two or more burners (BRNi), able to mix with said fuel gas, shut-off valves of the flow of said combustion air, an electronic unit (CMD) for controlling said air flow (QAIR).The air flow (QAIR) varies as a function of said flow of fuel gas (QGAS) in input into each of said two or more burners (BRNi) so as to ensure a gas-air mixture with a stoichiometric or substantially stoichiometric ratio without the need of input of secondary air from the outside, said variation of air flow (QAIR) being obtained by varying the pressure of the combustion air in said sealed circuit (CA1, 405, 407) inside said hob (400).Said pressure is intermediate to the single pressures that each active burner (BRNi) should have.
