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). |
