A hydraulic oscillator is advantageous due to its power amplification ability and strong durability while being placed under strenuous applications. In the previous report, we pres e nted the theoretical characteristics regarding new type hydraulic oscillators-an oscillator with a dead zone restoring force and an oscillator with low-supressed restoring torque with a small vibratory displacement. This paper presents an experimental analysis of these vibratory characteristics. That is, it has been experimentally confirmed that the vibratory characteristics of the oscillator with a quasi-dead zone restoring force agree very well with the theoretical characteristics of the oscillator with a perfect dead zone restoring force on condition that the values of parameter 1/ko are less than 0.15. As regarding the oscillator with a low-suppressed restoring torque, the experimental vibratory characteristics have been compared with the theoretical ones which were obtained from analogue simulations computed by using the restoring torque measured experimentally, and it was shown that the new type oscillator has lower frequency characteristics than the former oscillators.
