An electric valve device including a hollow body with an inlet and an outlet for a flow of fluid, in particular a liquid, between which, inside said body, there is defined a chamber in which there is provided a valve seat intended to cooperate with an associated closing member for controlling communication between the inlet and the outlet; and a tubular guiding formation which is nominally coaxial with the valve seat and inside which there is mounted, axially displaceably to and from the seat, a core which carries the closing member and the position of which with respect to the seat can be electromagnetically controlled by means of a winding or solenoid arranged around said tubular formation. The hollow body and the tubular guiding formation are made as a single piece of moulded plastic.

Electric valve device, in particular for a device for forming ice in a fridge

A device () includes a support structure (), on which there are mounted a plug (), which is adapted to assume a plurality of operating positions including an opening position and a closing position, in which the plug is adapted to at least partially free and respectively obstruct a passage (), which is meant for a fluid flow. A mechanism () is suited to move and hold the plug () between said operating positions. An opening actuator () and a closing actuator () are suited to separately act upon the mechanism (), so that the mechanism () moves and holds the plug () between said operating positions, namely towards said opening position and towards said closing position, respectively, due to electric current supplied to the opening actuator () and to the closing actuator respectively.

Valve device for controlling a fluid flow, in particular for controlling the cold air flow in a household appliance, such as a refrigerator

The pilot valve () comprises a body () in which there is defined a control chamber () which is intended to communicate with the inlet () of the hydraulic valve () and which, through a restricted outlet passage () associated with a valve seat (), is able to be selectively brought into communication with the outlet () of the hydraulic valve (); at least one core () mounted movably within a portion () of said body () and inside the control chamber () and carrying a closing member () cooperating with the valve seat (); and an actuator (-) including a solenoid or coil () of copper wire, mounted around said portion () of the body (), for selectively controlling the position of the core () and the closing member () with respect to the valve seat () and the communication between the control chamber () and the restricted outlet passage (); and wherein the ratio of the diameter (d) of the restricted outlet passage () to the weight (m) of the solenoid () is between 0.06 and 0.10 mm/g.
