In order to generate precise dynamic pressure, we are developing a dynamic pressure generator using a newly rotating valve. This paper describes the principle of the valve and the generator and some experimental results. The generated waveform is square whose amplitude and fundamental frequency can be changed. When the supplied difference pressure was 5kPa and the fundamental frequency was changed from 1 to 100Hz, we measured the waveform by a pressure transducer, and evaluated the amplitude and the mean value of the waveform. As an experiment result, the amplitude and the mean value of the generated pressure were almost constant in the frequency range from 1Hz to 50Hz.
