Abstract

PURPOSE: To improve the driving efficiency of a vibrator, by using spools solidly equipped with hydraulic vibrators and pilots and connecting an alternative passage of a pilot with a pilot chamber on both sides of another spool.
CONSTITUTION: When spools 7, 8 are in a state as shown in the figure, pressure oil from a pump 9 reaches a port 22b of a vibrating cylinder 21 through alternative passages 13, 17, while the other pressure oil from a pump 10 reaches pilot chambers 8a, 7a to move the spool 8 rightward. As the spool 8 shifts right, the pressure oil from the pump 9 reaches the port 22a of vibrating cylinder 21 through passages 13, 17 while that from the pump 10 reaches 8a, 7b to shift the spool 7 leftward. The driving efficiency of the vibrating cylinder 21 is greatly improbed because it is vibrated by the spools 7, 8 combined with the hydraulic oscillators and pilots.
