摘要： PROBLEM TO BE SOLVED: To provide a vibration controlling hydraulic damper that structurally avoids an overall form projecting in the direction perpendicular to a piston axis direction and avoids external exposure of a control valve device. SOLUTION: The vibration controlling hydraulic damper 100 interconnects two working chambers R1 and R2 formed on opposite sides of a piston 31 axially slidable in a cylinder body 10 via passages 12a, 12b, 15a, 14, 16a and 13a, and controls working fluid flowing in the passages by means of the control valve device Vo to damp a vibration of a structure. The two passages 12a and 12b in communication with the two respective working chambers R1 and R2 are opened to one axial end face of the cylinder body 10, the control valve device Vo is mounted detachably, and the passages 12a and 12b are connected to the control valve device Vo. A hollow coupling member 20 is coupled to the one axial end of the cylinder body 10 so as to house the control valve device Vo. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To simplify a constitution for preventing rotation of a spool without applying a special constitution for preventing the rotation to the spool.
SOLUTION: A supply flow passage P to supply a fluid to the inner circumference face of a first enlarged diameter part 5A of a fitting hole 5 for inserting the spool 6 to be slidable in the axial direction is opened, an annular space 7 is formed between the inner circumference face of the first enlarged diameter part 5A and the outer circumference face of the spool 6. A flow control member 81 formed in a cylindrical column shape is provided in the supply flow passage P1. The flow control member 81 has an axial dimension H set so that the flow rate of the fluid flowing into the annular space 7 from the supply flow passage P1 is substantially equal between the flow rate Q1 flowing in one circumferential direction of the annular space 7 and the flow rate Q2 flowing in the other circumferential direction.
