Abstract

PURPOSE: To provide possibility to adjust amplitude in an oil pressure oscillator by such a construction that oil-hydraulic piston is to be adjusted rotatingly by excavating an amplitude adjusting inclined groove in the circumferential surface of said oil-hydraulic piston on its constant pressure chamber side and by putting this inclined groove into communication with the constant pressure chamber of the oil-hydraulic piston.
CONSTITUTION: Around oil-hydraulic piston 4 on its constant pressure chamber 9 side, an inclined groove 32 for adjustment of amplitude is formed, and this groove 32 shall work in linkage with an oil supply hole 21 at which a spool actuating oil line 27 is opening to the cylinder's inner surface. Rotary adjustment of the piston 4 by putting this groove 32 into communication with the constant pressure chamber 9 through a communication hole 33 will change the point on groove 32 from which it is in communication with the oil supply hole 21 for the oil line 27 and adjust the timing when the pressure oil in the constant pressure chamber 17 is introduced into alternate pressure chamber 10 in the pilot valve 2 through the communication hole 33, inclined groove 32, oil supply hole 21 and oil line 27. Turning the piston 4, for example, in the direction of A will quicken the timings when the spool 5 begins moving upward and when the piston 4 begins moving downward, and accordingly the piston's sliding stroke, i.e. amplitude, is suppressed.
