Abstract

PURPOSE: To reduce an installation space, by making a vibration applying actuator main body movable for a piston and by providing a vibration stand on this vibration applying actuator.
CONSTITUTION: Pressure oil from crude oil liquid 5 has the direction and the flow rate controlled by servo valve 6 and is supplied to oil rooms 7d and 7e alternately through duct 10 and passage 9. By this oil supply, vibration applying actuator main body 7a reciprocates to apply vibration to vibration stand 1 and drive it. This machine is constituted by providing vibration stand 1 on vibration applying actuator main body 7a in this manner. Consequently, the length in the axial direction can be shortened in comparison with the unit where reciprocation of piston rod 3c of vibration applying actiator 3 is transferred to vibration stand 1 to apply vibration to it, so that the installation space can be reduced.
