<p>PROBLEM TO BE SOLVED: To provide an attenuation force control valve capable of attaining a stable attenuation force even if a flowing-in or flowing-out direction of working fluid is changed over.SOLUTION: This invention relates to an attenuation force control valve 10 in which the inner peripheral surface of a cylinder part 13 is formed with a first port 28 and a second port 29 communicating with a first passage formed at a plunger part 34. Both ends of the plunger part 34 are positioned in an inner space 30 and communicated to each other through a second passage 21 different from the first passage. When the first port 28 and the second port 29 are communicated to each other through the first passage as the plunger part 34 moves, a communicating portion of the first port 28 with the first passage and a communicating portion of the second port 29 with the first passage are generated at the same side in an axial direction of a cylinder part 13, the first port 28, the second port 29 and the first passage are positioned between both ends of the plunger part 34 in an axial direction of the cylinder part 13.</p> |
