  • Patent number: 9410653
    Abstract: 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).

  • Patent number: 8960638
    Abstract: A solenoid valve device that includes 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); 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 communicating the control chamber with the outlet (4); and a control solenoid valve (14) including a control solenoid (15) which controls a movable unit (17) including a first core (18) which can interact as a movable plug with the second passage (12, 13).

  • Publication number: 20120175541
    Abstract: A valve assembly including a valve body with inlet and outlet ports, between which there is a main valve seat cooperating with an associated main obturator. The obturator defines together with the valve body, a variable volume control chamber in permanent communication with the inlet port through a first passage having a reduced cross-section. The control chamber is adapted to be brought into communication with the outlet port through a second passage having a larger cross-section. Also provided is a solenoid pilot valve including a control coil and a movable core associated with an auxiliary obturator adapted to open and close the second passage. Between the second passage and the outlet port, is defined a second variable volume control chamber, which is delimited in part by the auxiliary obturator, and the movable core associated with the auxiliary obturator is mounted outside of the flow-path of the fluid.

  • Patent number: 4212589
    Abstract: A pump has a tubular membrane (14) deformed cylindrically by fluid driving pressure to produce an artificial blood circulation. The pump has a feeler (42) which follows the deformation of membrane (14) and operates a switch (102) to close the circuit of an optical signalling device (103) when the deformation of the membrane (14) reaches a predetermined value. A control circuit (104) may be provided for the automatic regulation of the fluid driving pressure acting on the membrane (14) in dependence upon the duration of the closure time of the switch (102). (FIG. 7).
