The regulating device () comprises a body () including a hub () which has a first end () connected to a surrounding ring (), such as to define therebetween at least one passage () for the fluid, between the upstream and downstream regions, and the other or second end () of which protrudes with respect to the ring (). The ring () has, on a surface thereof, an annular distribution of projections (). On the second end () of the hub () there is mounted a flexible, ring-shaped, regulating member () facing and spaced from the tops of said projections () and capable during use of resiliently flexing towards them as a result of and depending on the difference in pressure between the upstream and downstream regions. The ring () is further provided with a plurality of restricted holes () having a fluid flow parallel to the at least one passage (). These restricted holes () are formed essentially in the same radial portion (C) of the ring () in which the projections () are provided such that the holes () are circumferentially and radially comprised each between a pair of projections ().

Hydraulic flow-rate regulating device

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.

Solenoid pilot valve for a hydraulic valve, in particular for household appliances

An electric valve device including a body having an inlet and an outlet, and a main valve seat through which the fluid can flow from the inlet to the outlet, a main shutter movable with respect to the valve seat; a control chamber; first and second communication passages between the inlet and the control chamber and between the control chamber and the outlet, respectively; a fixed structure arranged in the control chamber and in which there is defined an auxiliary valve seat, which is coaxial with the main valve seat (8) and which communicates with said second passage; and a solenoid control valve including a control solenoid coaxial with the valve seats for controlling an auxiliary shutter mounted movably in the control chamber and cooperating with the auxiliary valve seat for controlling the communication between the control chamber and the second passage.

Electric valve device

A solenoid valve device that includes a body () with an inlet () and an outlet () for the fluid, and with a main valve seat () through which the fluid can flow from the inlet () to the outlet (); a main plug (); a control chamber () partially delimited by the main plug (); a first passage (,,) for communication between the inlet () and the control chamber (); a second passage () for communicating the control chamber with the outlet (); and a control solenoid valve () including a control solenoid () which controls a movable unit () including a first core () which can interact as a movable plug with the second passage (). Activation of solenoid () causes attraction of first core () towards a second core () and the opening of the second passage ().
