LIQUID PRESSURE PUMP FOR ELECTRIC DISCHARGE PROCESSING MACHINE OF FINE DEEP HOLE

摘要

PURPOSE: A liquid pressure pump is provided to minutely process and to economically operate the machine without the output loss. CONSTITUTION: The liquid pressure pump is composed of:a piston(1); a cylinder(2); a body(3) having compressed air channels(32)(32') connected with the inside of the cylinder(2), formed inside of the bodies(3)(3') and having moving channels(31)(31') moved by being inserted near the inside of piston rods(11)(11'), formed by penetrating in its center; a flange(4); and a master valve(5) for controlling the input and the exhaust of the compressed air fed through an inlet(53) of the compressed air on its front edge by sensors(S1)(S2) for sensing the movement limit of the piston(1).
