Abstract

PURPOSE: To prevent a striking action between the fluid fed from the pump and the fluid discharged from the power cylinder by a method wherein the valves are constructed such that the orifices formed in the servo valve are closed in sequence.
CONSTITUTION: First concave groove 31 is formed at an inner circumferential surface of the sleeve valve member 21, and the feeding port 33 is opened at the groove. Concave groove 38 is formed at an intermediate part of said groove 31. The lands 34, 35 for use in opening the distribution parts 36, 37 are formed at both sides of the groove 38. First land 39 and second land 41 are formed at an outer circumference part of the spool valve member 22. First orifices 50a, 50b are formed by the first land 39 and the land portions 34, 35, and the second orifices 60a, 60b are formed by the second land part 41 and the land portions 35, 34. Said orifice is provided with land portions so as to close the second orifices after the first orifice is closed.
