DIRECT-CURRENT ELECTRIC ACTUATOR, IN PARTICULAR FOR HOUSEHOLD APPLIANCES

The actuator (10) comprises a body (12) formed by a single strip of ferromagnetic material, U-shaped and including a first and a second lateral branch (14, 16) facing each other and interconnected byan intermediate branch or portion (8). A first lateral branch (14) of the body (12) has a frustoconical formation (30) which extends in the region outside the body (12). A coil (22) is fixed in the body (12), and its axis (A- A) extends in a direction essentially orthogonal to the lateral branches (14, 16) of this body (12). A ferromagnetic core (28) is mounted so as to be translatable inside thecoil (22), from a rest position to a working position, as an effect of the energising of the coil (22). One end (32) of the core (28), facing towards the first branch (14) of said body (12), has a frustoconical shape essentially complementary to the internal shape (30b) of the formation (30). The frustoconical formation (30) of the first branch (14) of said body (12) is blind and has a planar distal bottom wall (30a). 种致动器
