Abstract

PURPOSE: To perform driving operation of a vibration generating device at optional frequency of stable oscillation, by interposing a flow control valve in an oil motor discharged oil line.
CONSTITUTION: A feed-discharge controller B for controlling feed and discharge operation of working oil is constituted by oil lines 7, 8, respectively connected to two feed and discharge oil chambers 3, 4 located at a face-to-face position in a double acting hydraulic actuator A, rotary valve 11 interposed between a feed oil line 9 connected to an oil hydraulic power source and a discharge oil line 10, and an oil motor 12 for rotationally driving said rotary valve 11. Then in a stage immediately after the oil motor 12 in an oil motor discharge oil line 14, a flow control valve C is provided. In this way, when an oil hydraulically operated vibration generating device is driven to perform generating operation of vibration, a difference of pressure in the oil lines 7, 8 connected by the rotary valve 11, being in a small level, can suppress a change of rotary speed in the oil motor 12 to a very low range.
