摘要： PROBLEM TO BE SOLVED: To generate a stable damping force by suppressing a sudden fluctuation in oil pressure, in a damping force adjustable hydraulic shock absorber provided with a pilot type damping valve. SOLUTION: A first piston 3 and a second piston 4, coupled to a piston rod 10 are fitted into a cylinder 2, and an intermediate chamber 2C is formed between the first and second pistons. A contraction-side check valve 13 and an expansion-side check valve 16 are respectively provided at the first piston 3 and the second piston 4. An expansion-side main valve 18 and a contraction-side main valve 23 are disposed in the intermediate chamber 2C, and the downstream side of a damping force adjusting valve 36 is connected to the intermediate chamber 2C. Inner pressures of an expansion-side backpressure chamber 19 and a contraction-side backpressure chamber 24 are adjusted by the damping force adjusting valve 36, thereby controlling valve opening of the expansion-side main valve 18 and the contraction-side main valve 23. After oil downstream of the damping force adjusting valve 36 is temporarily led to flow into the intermediate chamber 2C, oil flows to a cylinder upper chamber 2A or a cylinder lower chamber 2B. Thereby, the stable damping force is generated by suppressing the sudden fluctuation in oil pressure. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a stabilizer device capable of easily performing the relative rotation and the relative rotation regulation of a shaft of a stabilizer.
SOLUTION: A roller 25 is arranged between a circular inner wall 8 of a bottomed member on a first bar 5 side and an octagonal outer wall 20 of a cam on a second bar 6 side. When a steering wheel is turned rapidly while the roller 25 is arranged at a center in the circumferential direction of a flat part of the octagonal outer wall 20 of the cam, a roller holding member 21 (the roller 25) stays at a position by electromagnetic forces generated by solenoids 32a, 32b; and the roller 25 is moved to the corner side of the flat part by the rotation of the second bar 6 and engaged with the bottomed cylindrical member 7 and the cam 12. Torsional rigidity is thereby generated in a stabilizer 4 to suppress a roll behavior.

摘要： PROBLEM TO BE SOLVED: To provide a damper having a simple configuration and capable of adjusting magnitude of damping force by corresponding to a travel position.
SOLUTION: An annular body 8 made of a non-magnetic material is provided between an upper side cylindrical body 7a and a lower side cylindrical body 7b made of a magnetic material, and a piston 16 is stored in a first chamber 3 of a cylinder 2 so as to move vertically. The piston 16 is composed of a guide member 17 forming a flow passage 20 in an outer peripheral part and a piston main body 18 made of a magnetic material, and a clearance 19 constituting a flow passage 21 together with the flow passage 20 is formed between the piston main body 18 and the cylinder 2. A permanent magnet 15 is provided on an outer peripheral side of the cylinder 2 corresponding to the annular body 8. Facing situation of the piston main body 18 for the annular body 8 and the cylindrical body 7 is changed in accordance with travel of the piston 16, and size of magnetic field acting on magnetic fluid 6 is changed. For this reason, viscosity of magnetic fluid 6 is changed, and magnitude of damping force acting on the piston 16 is changed.
