The active utilization of the pressure rise phenomenon of an oil hammer and a new type of hydraulic pressure intensifier using an oil hammer were proposed and developed. In this research, an application of this intensifier to a hydraulic cylinder of a construction machine is studied through experimentation and simulation. High pressure is generated when the fluid flow through the pipeline is shut quickly by the solenoid operated valve at the downstream end. If the fluid is taken out through the check valve when the pressure is high, much higher-pressure fluid than the supply is obtained. Therefore the pressure is intensified. The purpose of this research is to help apply this device to industrial machinery. The necessary level of increased pressure is thought to be around 30MPa to apply it to an actual machine. We intend to find a suitable pipeline length and diameter, in order that low pressure supplied by a pump may be increased to the necessary high pressure by an oil hammer.
