The electrically controlled valve (10) comprises * a support structure (12) having, defined internally, a chamber (16) which is able to be passed through by a fluid flow and which has an inlet (18) and a first outlet (20a; 20b); * an obturator (22) movable inside the chamber (16) between a first and second working position, in which it respectively closes off and clears the first outlet (20a; 20b); and * an electrically controlled operating assembly (26) associated with the obturator (22) and able to cause switching of the obturator (22) into the first and second working positions. The operating assembly (26) includes a toggle mechanism (32) which is able to assume two stable positions and is connected to the obturator (22) and which comprises: a rigid member (34) rotatable with respect to the support structure (12) and a resilient member (36) arranged between the rigid member (34) and the support structure (12). The resilient member (36) tends to retain the toggle mechanism (32) in a first or a second configuration corresponding, respectively, to the first and second working position of the obturator (22). The operating assembly (26) also includes first and second actuator members (52, 54) which are able to be activated by means of electric control, are kinematically linked to the rigid member (34) and are able to assume a first/second arrangement, when the first and second actuator members (52/54) are respectively activated/deactivated and deactivated/activated, so as to impart an oscillating movement to the rigid member (34) of the toggle mechanism (32), causing switching thereof into the second/first configuration respectively. |
