Abstract

PURPOSE: To obtain the smooth motion of an operating part, and to reduce the size of the motor, by installing each of the hydraulic cam pumps in the pipeline between an antirod-side chamber and a check valve.
CONSTITUTION: Cams 22, 23 (24), 25 (26) are rotated by the driving device, and a hydraulic cam pump 9 is driven by the cam 22 along its curved surface. The working oil in the inside of the pump 9 becomes pressurized and supplied to the antirod-side chamber 1 of an advancing cylinder 1 which is controlled of its stroking speed corresponding to the rotating speed of the cam 22 to advance a feed bar. The cam 22 further rotates and as it comes close to its bottom part, the pressure of the oil in the inside of the antirod-side chamber 1 of the advancing cylinder 1 is lowered. Then the pressure oil in the inside of an accumulator 8 is applied to the rod- side chamber 1 and makes the feed bar return.
