Title:
DAMPING VALVE AND SHOCK ABSORBER
Document Type and Number:
WIPO Patent Application WO/2016/195008
Kind Code:
A1
Abstract:
[Problem] To provide a damping valve that can reliably block the flow channel at a desired pressure and a shock absorber. [Solution] A damping valve comprises: a piston (10) that has a valve hole (H) by which an extension side chamber (L1) and a compression side chamber (L2) communicate; a valve body (6) that has a sliding shaft (60a) inserted into the valve hole (H) so as to be able to slide; a step (10e) that regulates motion of the valve body (6) toward the compression side chamber (L2); a coil spring (8) that biases the valve body (6) toward the compression side chamber (L2); and a flow channel (62), one end of which opens to the side of the sliding shaft (60a) and the other end of which opens further toward the extension side chamber (L1) side than the sliding shaft (60a) of the valve body (6). The flow channel (62) is blocked when the valve body (6) moves to the extension side chamber (L1) side and the one end opening (o1) of the flow channel (62) faces the wall face of the valve hole H that is in sliding contact with the outer circumference of the sliding shaft (60a).
