Title:
BUFFER
Document Type and Number:
Japanese Patent JP2017048848
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a buffer which can achieve sufficient damping force effect when compressed by a high frequency vibration input, and can increase a reduction width of a compression side damping force.SOLUTION: A buffer D according to the invention is provided with a first bypass passage B1, a first pressure chamber PR1, a first free piston F1, and a first spring S1 for an extension side damping valve EV which exerts an extension side damping force to allow the extension side damping valve EV to be bypassed, and with a second bypass passage B2, a second pressure chamber PR2, a second free piston F2, and a second spring S2 for a compression side damping valve CV which exerts a compression side damping force to allow a compression side damping valve CV to be bypassed.SELECTED DRAWING: Figure 1
