A method of discharging a fluid, includes feeding a fluid into a gap defined between two surfaces in a closed space, and relatively oscillating the two surfaces to apply relative oscillation with high frequency to the gap so as to occur a squeeze pressure to the gap, and thus intermittently discharging the fed fluid through a discharge port provided in either one of the two surfaces by using the squeeze pressure.

Un metodo di scaricare un liquido, include inserire un liquido in uno spacco definito fra due superfici in uno spazio chiuso e relativamente oscillare le due superfici per applicare l'oscillazione relativa con frequenza allo spacco in modo da accadere una pressione di compressione allo spacco e così intermittentemente scaricare il liquido del fed attraverso un orificio di scarico fornito in uno una delle due superfici usando la pressione di compressione.
