Abstract

PURPOSE: To provide a fluid pressure equipment which is used for the hydraulic operation of a triaxial tester or the like, generates a high fluid pressure corresponding to the regulating pressure of the pressure regulator by using it, and loads the generated fluid pressure at a constant pressure.
CONSTITUTION: When a disk 19 having risen contacts with a limit switch L2, a solenoid valve D is operated to open an air hole 9, and from the other air hole 8 air is supplied into an air cylinder 5 at a pressure set by a pressure regulator, and so an air piston 10, an oil hydraulic piston 11 and a piston shaft 12 lower rotating in a body. Consequently, the internal pressure in an oil hydraulic cylinder 2 is a positive pressure, which causes a switching valve 23 to be closed and the other switching valve 24 to open, and a high fluid pressure corresponding to the pressure set by the pressure regulator is loaded from a connecting port 28. The air pressure is continuously loaded to keep a constant pressure state until the lowering of the air piston 10 is detected by a limit switch L1 at the lowering point.
