Abstract

Provided is a valve device and a shock absorber that can prevent them from being in a failure state at the normal time and can freely set a passive valve even when both pressure control and passage opening/closing are performed by a solenoid valve. For this reason, the valve device includes a first passage and a second passage connected downstream of the pressure introducing passage, a solenoid valve that opens the first passage to control the upstream pressure and closes the second passage when energized, and that closes the first passage and opens the second passage when not energized, and a passive valve provided downstream of the solenoid valve in the second passage.
