Abstract: A cushion valve device includes a valve block that includes first, second and first discharge passages. The first passage is disposed between a first supply/discharge passage of an operating valve and a first pilot passage of a switching valve, and includes a first throttle. The second passage is between a second supply/discharge passage of the operating valve and a second pilot passage of the switching valve. The first discharge passage connects to the first passage and a tank. A first check valve is provided on the first discharge passage. The first check valve includes: a poppet valve element configured to be seated on a valve seat portion, thereby closing the first discharge passage; and a piston configured to move the poppet valve element when the pressure of pilot oil in the second supply/discharge passage has become higher than or equal to a predetermined pressure, thereby opening the first discharge passage.
