DAMPER |
摘要 |
A damper includes a cylinder, a piston that is inserted into the cylinder, a rod that is connected to the piston, a rod-side chamber and a piston-side chamber that are divided within the cylinder, a tank, an extension-side passage that allows communication between the rod-side chamber and the tank, a compression-side passage that allows communication between the piston-side chamber and the tank, an extension-side damping valve that is provided in the extension-side passage, a first check valve that is provided in the extension-side passage in parallel with the extension-side damping valve, a compression-side damping valve that is provided in the compression-side passage, a second check valve that is provided in the compression-side passage in parallel with the compression-side damping valve, and a center passage that allows communication between the tank and the inside of the cylinder. |

1. A damper comprising:
a cylinder, a piston slidably inserted into the cylinder, a rod that is inserted into the cylinder and connected to the piston, a rod-side chamber and a piston-side chamber that are divided within the cylinder by the piston, a tank, an extension-side passage that allows communication between the rod-side chamber and the tank, a compression-side passage that allows communication between the piston-side chamber and the tank, an extension-side damping valve that is provided in the extension-side passage and applies resistance to a flow of liquid from the rod-side chamber toward the tank, a first check valve that is provided in the extension-side passage in parallel with the extension-side damping valve and allows only passage of liquid from the tank to the rod-side chamber, a compression-side damping valve that is provided in the compression-side passage and applies resistance to a flow of liquid from the piston-side chamber toward the tank, a second check valve that is provided in the compression-side passage in parallel with the compression-side damping valve and allows only passage of liquid from the tank to the piston-side chamber, and a center passage that allows communication between the tank and the inside of the cylinder. |
