When oil flows through a pipeline, and the flow is stopped suddenly, very high pressure is generated. This is called an oil hammer phenomenon. We are developing a device to intensify pressure using an oil hammer. We succeeded in obtaining several times higher pressure than supplied one. When high-pressure is necessary, this device can turn low pressure into high pressure. Therefore, a hydraulic pump can be smaller, and saveenergy. The purpose of this research is to help apply this device to industrial machinery. To apply it to an actual machine, the necessary level of increased pressure by an oil hammer is about 30MPa. We intend to find a suitable pipeline length, diameter, and line shape, in order that low pressure supplied by a pump may be increased to high pressure.
