摘要： The valve assembly (1) comprises a valve body (3-5) with an inlet port (6) and an outlet port (7) for the fluid, between which there is defined a main valve seat (9) intended to cooperate with an associated main obturator (10). The main obturator (10) defines together with the valve body (3-5), a variable volume control chamber (13) which is in permanent communication with the inlet port (6) through a first passage (11) having a reduced cross- section. The control chamber (13) is adapted to be brought into communication with the outlet port (7) through a second passage (24) having a larger cross-section. The valve assembly (1) also comprises a solenoid pilot valve (17) including a control coil (18) and a movable core (19) associated with an auxiliary obturator (21) which is adapted to open and close the second passage (24). In the valve body (3-5), between the second passage (24) and the outlet port (7), there is defined a second variable volume control chamber (22), which is delimited in part by the auxiliary obturator (21), and the movable core (19) associated with the auxiliary obturator (21) is mounted outside of the flow-path of the fluid, in particular outside of the second variable- volume control chamber (22).

摘要： The regulating device (1) comprises a body (2) including a hub (3) which has a first end (3a) connected to a surrounding ring (4), such as to define therebetween at least one passage (6) for the fluid, between the upstream and downstream regions, and the other or second end (3b) of which protrudes with respect to the ring (4). The ring (4) has, on a surface thereof, an annular distribution of projections (7). On the second end (3b) of the hub (3) there is mounted a flexible, ring-shaped, regulating member (8) facing and spaced from the tops of said projections (7) 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 (4) is further provided with a plurality of restricted holes (10) having a fluid flow parallel to the at least one passage (6). These restricted holes (10) are formed essentially in the same radial portion (C) of the ring (4) in which the projections (7) are provided such that the holes (10) are circumferentially and radially comprised each between a pair of projections (7).

摘要： A valve assembly includes a valve body, having an inlet duct, an outlet duct and an intermediate portion. An electrovalve is located proximal to the intermediate portion. A measurement device is directly connected to the valve body. The measurement device includes a sensor for taking a measurement for determining a physical characteristic of the fluid that can flow in the valve assembly. The electrovalve includes a first electronic circuit for conducting an electric control signal from a control unit to the electrovalve. The measurement device includes a second electronic circuit for conducting the electric signals exchanged between the control unit and the sensor. The first electronic circuit and the second electronic circuit are implemented on a single header or printed circuit board. The electrovalve and the measurement device are mechanically connected directly to the single header or printed circuit board.

摘要： The device (1) comprises: - a body (2, 7) with an inlet (3) and an outlet (4) for the fluid, and with a main valve seat (6) through which the fluid can flow from the inlet (3) to the outlet (4), - a main plug (8, 9) associated with this main seat (6), - a control chamber (11) partially delimited by the main plug (8); - a first passage (8d, 9b, 9c) for communication between the inlet (3) and the control chamber (11); - a second passage (12, 13) for putting the control chamber (11) into communication with the outlet (4); and - a control solenoid valve (14) including a control solenoid (15) which controls a movable unit (17) comprising a first core (18) which can interact as a movable plug with the second passage (12, 13). The movable unit (17) comprises a second movable ferromagnetic core (21), adjacent to the first core (18). A spacer element (19) extends between the main plug (8, 9) and the second core (21). One or more springs (20, 22) push the second core (21) towards the main plug (8, 9). The second core (21) is permanently fixed to the main plug (8, 9) and, when the solenoid (15) is inactive, the first core (18) is kept in the closed position of the second passage (12, 13), and the second core (21) is in a predetermined position with respect to the first core (18) such that the cores (18, 21) are separated by a gap (24). The activation of the solenoid (15) causes an attraction of the first core (18) towards the second core (21) and the opening of the second passage (12, 13).
