Abstract: The device comprises: a solenoid valve of the bistable type controlled by means of an operating winding; a control circuit coupled for operation to a power supply source and capable of supplying to the operating winding of the solenoid valve a first and a second current pulse, for opening and closing the solenoid valve respectively; and a detecting and operating device associated with the said solenoid valve, capable of detecting a predetermined dangerous operating condition thereof, and of causing, in such a case, the automatic reclosing of the valve for cutting off the flow of the fluid.

Abstract: The device (1) comprises a support structure (2) in which at least a first opening (8, 9) is defined, a shutter (13) which is mounted for piloting in that structure (2) and which is adapted to take up a least a first and a second angular position, in which it closes and opens at least partially the first opening (8, 9) of the structure (2), respectively, and an actuator device (25) which is capable of bringing about a controlled angular movement of the shutter (13) relative to the support structure (2).

Abstract: The device comprises a tubular stator intended to be fixed in a pipe, so as to be traversed, in use, by said stream of fluid, and in which there is axially mounted a rotor which has a central hub from which extends a plurality of blades and which is capable of being operated in rotation by said stream, like a turbine, at a velocity variable according to the flow rate, and at least one permanent magnet integral with the rotor, disposed eccentrically with respect to the axis of rotation of said rotor. Fixed to the hub of the rotor is a shaped support bush mounted rotatable about a fixed pin or shaft which extends, projecting in the opposite direction to the operational direction of flow of the stream, from a central support integral with the axial outlet portion of the stator. The magnet is held in a housing defined between the support bush and the rotor.

Abstract: The device comprises a shaped body to be fixed to the door of a dishwasher. The body comprises two half-shells of moulded plastics material, that is, a front half-shell and a rear half-shell, respectively, which are shaped in a manner such as to define between them at least one region or chamber suitable for housing a quantity of a liquid washing or rinsing agent. The front half-shell is opaque and has, in a wall of the chamber, a level-indicating aperture or window which is closed by an at least partially transparent element and which, in use, when the door of the machine is open, provides a visual indication of the quantity of agent contained in the chamber. The at least partially transparent element is formed by a wall moulding formed integrally with the rear half-shell and welded in a liquid-tight manner to the wall of the front half-shell in the vicinity of the said opening or window.

Abstract: The actuator comprises: an actuator member which is moveable relative to the structure and can perform an actuation movement in one direction and a return movement in the opposite direction, an electric motor including a rotor portion which can translate from a first, rest axial position to a second, working axial position as a result of an energization of the stator and against the action of a spring, a gear transmission which is coupled to the actuator member and can be coupled for rotation with the rotor portion when the latter is in the working axial position in order to bring about an actuator movement of the actuator member, and a stop device with a retaining member which can adopt an inactive condition and an active condition and an active condition in which it permits and prevent a return movement of the actuator member, respectively.
