PURPOSE: A method of obtaining high pressure of air or water using an ejector is intended to provide high-pressure water or compressive air by shooting water or air to an ejector. CONSTITUTION: An ejector(3), a fluid supply unit(a pump or a compressor) and a tank(1) receiving fluid from the ejector are connected by pipes. They are closed except low pressure of a suction unit of the ejector. The driving force of the ejector is supplied by the pump or the compressor and fluid from the ejector flows into the closed tank which stands given pressure. The pump or the compressor operates to suck water or air from the tank, the water or the air is shot to the ejector to suck air through the low-pressure suction unit of the ejector. Pressure in the tank is raised to a desired value, wherein if pressure of the low-pressure suction unit is over atmospheric pressure, the pressure in the tank also becomes over atmospheric pressure. |
