Abstract:
An electric valve device (1) for household appliances, includes a hollow body (2) with an inlet (4, 5) and an outlet (5, 4) for a flow of a liquid, between which in the body (2) there is defined a chamber (6) wherein a first valve seat (7) is provided, a (first) obturator (17) moveably mounted in the chamber (6) and cooperating with the first seat (7) for controlling the communication between the inlet (4, 5) and the outlet (5, 4), and a movable member (12) coupled with the obturator (17) and displaceable towards and away from the first valve seat (7) and controlled by means of an electrically operable actuator (10) carried by said body (2). In the body (2) a second valve seat (8) is staggered with respect to the first valve seat (7) along the direction of displacement of the first obturator (7), to which is connected a second obturator (18) displaceable from and towards the second valve seat (8). The arrangement is such that the obturators (17, 18) are jointly displaceable away from and towards the corresponding seats (7, 8), with which they define a first and respectively, second valve, fluidically in series with one another, and both controllable through said electrically operable actuator.
