Abstract: The present invention relates to a galvanic process additivated with nanotechnology, wherein silver nanoparticles are added to the composition of a galvanic bath (10b), capable of forming a nickel layer (101), onto which a chrome layer (102) is deposited to form a material with antibacterial properties, which may be applied in manufacturing the most varied devices or materials.

Abstract: The present invention relates to a bistable-type solenoid valve, composed by a valve assembly including a valve seat and a valve-seat orifice and a solenoid assembly including a coil that houses, at least partly, a valve member displaceable by an electromagnetic force generated by a coil, a magnet and an adjustment element adjacent the magnet. The valve member, upon being displaced, travels a distance in the direction of the valve-seat orifice until said orifice is obstructed, thus causing the valve to close, or in the opposite direction so as to clear said orifice, thus causing the valve to open. The adjustment element of the solenoid assembly adjusts the distance, thus enabling one to compensate the variations of dimensions of the parts that compose the solenoid assembly, so that such variations will not impair the good operation of the valve.
