A volumetric flow meter, including a casing () fitted into a duct (C;) and including a base body () and a cap () cooperating to define a housing chamber (), the housing chamber () being on opposite sides delimited by a base plane () formed in the base body () and by a cap plane () formed in the cap (). Through the cap () there is formed an inlet passage () communicating with the housing chamber () and extending orthogonally to the base plane (). Through a bottom () of the base body () there is an outlet passage () communicating with the housing chamber () and extending orthogonally to the base plane (). The flow meter has rotors () mounted rotatably within the housing chamber (), a permanent magnet () arranged on board one of the rotors (), and a magnetic sensor ().

A device for measuring the flow rate includes an impeller rotatably mounted in a conduit about an axis, and a detector indicating the angular speed of the impeller. A diffuser has a plurality of passages for dividing the flow into reduced flows which are directed toward the vanes of the impeller to cause rotation. The diffuser forms peripheral passages which extend in planes parallel to the axis and inclined in a same direction about the axis. Each passage has a longitudinal inlet portion, parallel to the axis and a transverse outlet portion laterally facing a first axial portion of the impeller such that in operation, the outlet portions of the passages direct towards the vanes of the impeller corresponding flows or jets of fluid in non-radial directions inclined in a same direction around the axis.

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 ().
