Abstract: A valve for adjusting the flow-rate of fluids, servo-controlled by an electric motor having within a hermetic enclosure capsule and supported rotatably with a support for reducing rotary friction, the rotor component of the electric motor with a screw-and-nut coupling with a flow control element restrained to perform only axial translational motions in a valve body provided with intake and discharge ports and fixed coaxially to the capsule. The support is provided by a radial bearing and associated with the rotor component in a position corresponding to the portion of the rotor component inside which the screw-and-nut coupling is provided.

Abstract: An air humidification system for large enclosed spaces, comprising at least one humidification line constituted by at least one humidification module comprising a box-like container with a water flow pipe inside which is functionally connected at its inlet to a water pump and at its outlet to a water discharge space. The pipe has, along its extension, a plurality of nozzles adapted to provide a water aerosol. The nozzles are open onto a first opening provided in the box-like container and are oriented toward the outside of the first opening. A cross-flow impeller is provided within the box-like container along a rotation axis which is parallel to the pipe and is suitable to aspirate air from a second opening of the box-like container and direct it toward the first opening.

Abstract: An airless atomizing nozzle comprises a tubular body including a bore having an inlet and an outlet; a cylindrical member including a face and a cylindrical delivery channel secured at the outlet, the delivery channel having substantially uniform diameter; and a pin including a target area spaced from and directly over the delivery channel outlet. The delivery channel includes a tapered inlet and an outlet terminating at the face. A method for aligning a target on a pin over an orifice in an airless atomizing nozzle body is also disclosed.

Abstract: A flow-rate adjustment valve for fluids, servoactuated by means of an electric motor, comprising a valve body constituted by a tubular cup formed by drawing, which is contoured so as to accommodate a guiding element for a flow control element and so as to engage first intake and discharge tubes formed by drawing at the ports.
