Abstract: The method is for discharging water through a faucet. The nozzle is attachable to a faucet and switchable between a spray-mode and a mist-mode. An inner cavity has filters and a water rotating device. The housing has an opening defined therein in fluid communication with the inner cavity and grooves and an orifice at a bottom portion thereof. The second filter is disposed below the opening. When in the spray-mode, water flows out through the opening and through grooves and is discharged as spray and mist at a bottom of nozzle. When switched to the mist mode, water only flow through the second filter but not through the opening. Water flows through the water rotating device to create a rotation of the water and the rotating water is discharged through the orifice as mist.

Abstract: A fountain for creating a vortex includes a base housing with a lower reservoir therein.

Abstract: The disclosure relates to a fuel injection valve that includes a valve needle, a closing spring applying a spring force to the valve needle, which spring force loads the valve needle in the direction of a closing position, and an actuator assembly. A coil of the actuator assembly produces a magnetic force on a magnet armature of the actuator assembly such that, as the magnet armature travels toward a pole piece of the actuator assembly, the magnet armature covers an idle stroke to a stop element of the valve needle and then carries the valve needle toward the pole piece. A spring constant of the closing spring and the magnetic force are matched such that the magnitude of the resultant force of the spring force and the magnetic force decreases with increasing distance of the valve needle from the closing position and remains the same with increasing the distance.
