Title:
VALVE MECHANISM, ATTENUATION FORCE GENERATION DEVICE AND SHOCK ABSORBER
Document Type and Number:
Japanese Patent JP2017180608
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To adjust a generating attenuation force with higher accuracy.SOLUTION: A control valve part 60 includes: a valve body 72 having an opening 77 in which an oil circulates; a first vale 71A and a spacer 73 in which the valve body is opposed to a valve seat 63 with a gap of a predetermined dimension; a solenoid actuator which moves a drive valve 61 in a direction approaching the valve seat, and which makes a gap between an inner peripheral part of the valve body and the valve seat variable by elastically deforming the valve body in the direction in which the inner peripheral part approaches the valve seat with respect to an outer peripheral part of the valve body; a cylindrical sleeve 78 provided movably in a valve seat member 50; and a coil spring 79 accommodated in the valve seat member, and for generating an energization force for moving the sleeve when energization of the drive valve by the solenoid actuator is released. When the energization of the drive valve by the solenoid actuator is released, a flow passage cross sectional area of an oil is reduced by the sleeve moving by the energization force of the coil spring, and an attenuation force is exhibited.SELECTED DRAWING: Figure 9
