Abstract
A damping valve comprises a through-hole forming a passage for a working fluid. A poppet having a center axis is seated on a valve seat around the through-hole. The poppet is housed in a housing so as to be free to slide along the center axis. The poppet is pressed against one wall surface of the housing by a biasing mechanism, that biases the poppet in a direction perpendicular to the center axis, vibration of the poppet is thereby suppressed.
